Introduction
Connecting the DC buses of frequency converters together results in energy savings
and in some cases simplifies the connection to the main supply. With common DC
the braking energy of one converter can be used for the other converters and
motors.
Unequal current distribution and different charging methods cause difficulties to
common DC systems:
• Unequal current distribution is influenced by input cables, AC or DC chokes and
input bridges’ forward characteristics. If the voltage reduction over the supply
components mentioned is not the same with all converters, more current will flow
through the converter which has a lower voltage reduction. Factors which
influence the current distribution include temperature, tolerances of components
and in DC choke cases the input cable’s cross-sectional area and length.
• Charging methods vary depending on the converter size. Because of this in some
installations, the supplies of the frame sizes R2-R4 should be disconnected when
they are connected parallel with frame sizes R5-R8.
Note: The drive compliance with the EMC Directive on low voltage networks is
specified in the appropriate Hardware Manual. However, please notice that different
common DC configurations have not been tested according to the EMC
requirements of conducted and radiated emissions.

Figure 2. Common DC connections. Cases c, d1 and d2.
Cases b, c and d can be used when the total power taken from the main supply,
Pout.tot, is smaller than the drive power rating, Pcont.max, of the biggest converter.
Possible main supply connections
9
Case a)
The most common set-up, where all converters are connected to the main supply.
When the charging circuits of the converters are different, this connection is not
always allowed. Table 1 shows when the connection cannot be used.
Case b)
Converters are identical and only one converter is connected directly to the main
supply.
Case c)
Converters are not identical and only the biggest converter is connected directly to
the main supply. The AC cables to the other converters are protected by
drive-specific fuses.
Case d1)
Converters are identical and only one converter is connected directly to the main
supply. The charging circuit of the connected converter is capable of charging the
whole DC bus.
Case d2)
Converters are not identical and only the biggest converter is connected to the main
supply. Charging circuit of the connected converter is capable of charging the whole
DC bus.
Note: If the charging circuit in case d1/d2 is not capable of charging the DC bus,
connection presented in case b/c must be used.
Note: With frame sizes R5...R8 the charging circuit in case d1/d2 might not be able
to withstand the three times larger charging energies. In this case the main supply
cable is wired to all of the input rectifiers as presented in case b/c.
Note: With ACS800-11 only connection presented in case d1/d2 is allowed.
Note: With ACS800-11 220 V units, the voltage drop over the charging resistor
during charging can generate a permanent undervoltage fault. Contact your local
ABB representative for help on designing the common DC configuration!
To determine whether it is possible to leave some converters unconnected to the
main supply see Appendix A Charging circuit capacity.
Possible main supply connections
10
Step by step guide
1) Select the converters and preselect the main supply connection. See Possible
main supply connections and Appendix A Charging circuit capacity.
2) Check from Table 1 that the connection is possible.
3) Check by using equation 1 that the load does not exceed the total power limit
Pout.tot of the system. See Power limit.
4) Select the fuses, cables and possible contactors for the DC side. See Fuses,
Cables and Contactors, DC bus and brake circuit.
5) Calculate the braking power and determine whether the braking cycle can be
performed and whether an internal or an external brake chopper is needed. See
Allowed braking power and need for a brake resistor.
6) If resistor braking is needed, select the internal or external brake chopper, the
resistor and the contactor. See Internal brake chopper, External brake chopper and
Contactors, DC bus and brake circuit.
7) Set up the common DC system according to the wiring instructions. See Wiring.
8) If the input terminals of frame sizes R7 and R8 are left unconnected, make sure
that the AC fans are powered separately. See Appendix B Powering the AC fans of
R7 and R8.
9) Set the common DC system related parameter values. See Start-up.
Step by step guide

Design
Power limit
Total output power limit of the common DC system can be calculated with
equation 1.
(equation 1)
P out.tot = P 1cont.max + k ⋅ P 2cont.max + k ⋅ P n.cont.max
Pout.tot is the instantaneous power limit of the installation. P1cont.max is the lowest
and Pn.cont.max the highest drive power rating of the converters.
Only converters, which are connected to the main supply, are used for the power
limit calculations.
The power correction factor, k, for each combination can be found from Table 1.
When several converters are connected to the main supply, the least efficient power
correction factor is chosen from table 1, i.e. the smallest factor. See Example1 and
Example2.

Explanations of Table 1:
NO: The supply of the smaller converter MUST NOT be connected, because the
converters have different input chokes. Frame sizes R2...R3 have DC chokes and
frame sizes R4...R8 AC chokes.
C: If both converters are connected to the main supply, the DC links MUST be
connected together via contactor because the converters have different charging
circuits. In R2...R4 the charging resistors are in series with the DC capacitors and in
R5...R8 the charging resistor is in parallel with the input bridge. The DC contactors
are switched on after all of the DC links are charged and the converters are in the
READY state.
Note: The Pout.tot value is higher if the smallest converter is not connected to the
main supply.
Design

Example1
The DC buses of three converters ACS800-0004-5, 2.2 kW, R2; ACS800-0025-5,
18.5 kW, R3 and ACS800-0025-5, 18.5 kW, R3 are connected together. The input
terminals of the 2.2 kW converter are left unconnected. According to Table 1, k = 0.5
when two R3´s are connected to the main supply, therefore Pout.tot is
P out.tot = 18.5kW + 0.5 ⋅ 18.5kW = 27.75kW
Example2
The DC buses of three converters ACS800-0050-5, 37 kW, R5; ACS800-0140-5,
110 kW, R6 and ACS800-0320-5, 250 kW, R8 are connected together. All three
converters are connected to the main supply. According to Table 1, k = 0.7 when R5
and R6 are connected to the main supply and k = 0.6 when R6 and R8 are
connected to the main supply. The worst case is chosen for the calculations, i.e.
k = 0.6, therefore Pout.tot is
Pout.tot = 37kW + 0.6 ⋅ 110kW + 0.6 ⋅ 250kW = 253kW
Design
13
Fuses
Use fuses listed in the appropriate drive Hardware Manual for input cable protection.
The recommendations for obligatory DC side semiconductor fuses, aR fuses, are
listed in Table 2. Use 690 VAC rated fuses for 230...500 V converters and 1250 VAC
rated fuses for 690 V converters. The aR fuses protect the converter against short
circuits in other converters. Because of the complicated fault current paths the
selectivity of the fuses cannot be guaranteed in all conditions.
aR fuses must be installed on both DC wires.

Cables
• Select the input power cables as described in the appropriate drive Hardware
Manual. The cross-sectional area of the DC cables must be the same as the
cross-sectional area of the AC side cables.
• If screened DC cables are used, ground the screen at the other end only.
• The lengths of the supply cables must not differ more than 15%. This applies
especially to converters equipped with DC chokes.
• Maximum length of the DC cables between two converters is 50 m.
• If the system consists of more than two converters, the DC links must be
connected in an external terminal box. Do not use the terminals of one of the
converters for this purpose.

Allowed braking power and need for a brake resistor
1. For each drive check that the braking power does not exceed the allowed braking
power. See Calculation of the allowed braking power below.
2. For the common DC system check whether it needs to be equipped with an
additional brake chopper and resistor. This is the case if the total power of the
common DC system is negative at any point of the duty cycle [i.e. braking motor(s)
regenerate more power to DC link that can be consumed by other motors]. See the
figure below which shows the duty cycles of three drives and the sum, the common
DC duty cycle. A brake chopper and a resistor is needed to dissipate the surplus
braking energy (the shaded areas).

Calculation of the allowed braking power
If drive is not connected to the main supply, ensure that the braking power meets
condition 1 below.
If drive is connected to the main supply, ensure the braking power meets condition 1
AND condition 2 below.
Condition 1
The drive braking power may not exceed the drive power rating.
P br ≤ P cont.max
Pbr
= braking power
Pcont.max = drive power rating
Condition 2
The power flowing through the converter's DC bus terminals to the other drives may
not exceed the drive power rating. This might happen when drive brakes and takes
power from the main supply at the same time. The power rating of the terminals is
not exceeded when the following condition is valid, i.e. the sum of the drive input
power and the drive braking power has to be equal or smaller than the drive power
rating.

Need for a brake resistor
The total power of the common DC system is negative during phase interval t3...t4,
therefore a brake chopper and a brake resistor are needed.
Design
18
Internal brake chopper
• Only one internal brake chopper is allowed to be active.
• If an internal chopper is used, it must be in the biggest converter.
• The maximum braking power of the brake chopper or the inverter must not be
exceeded.
• A contactor must be used in the resistor circuit for protection against brake
chopper faults and against the overtemperature of the resistor.
External brake chopper
• An external brake chopper can be used but not at the same time with an internal
brake chopper.
• The external chopper must be installed close, < 5 m, to the biggest braking
converter.
• The external chopper can be selected according to the braking power demand.
For more information, see the appropriate drive Hardware Manual.
• A contactor must be used for protection against brake chopper faults.
Contactors, DC bus and brake circuit
If converters with different charging circuits are connected directly to the main
supply, the DC links must be connected together via contactors. See Table 1.
With an external or an internal brake chopper a contactor must be used for
protection against brake chopper faults.
• Contactors must be capable of cutting off the DC current. The maximum
operational voltage over the contactor is the DC voltage during the braking, i.e.
1.21 · 1.35 · U1.
• DC current rating for the DC contactor can be calculated by using equation 4.
P DC
I DC = ---------U DC
P DC ≈ P cont.max
(equation 4)
U DC = 1.35 ⋅ U 1
Pcont.max is the drive power rating of the biggest converter and U1 is the supply
voltage of the converter.
Design
19
Peak current through the contactor in brake resistor circuit can be calculated with
equation 5.
1.21 ⋅ U DC
Î = ------------------------R brake
(equation 5)
The rms current during the braking can be calculated with equation 6.

(equation 6)
Rbrake is the brake resistor‘s resistance. Pbr is the applied braking power.

Wiring
Supply
Use the same supply connection point. All converters must be fed from the same
transformer. The supply impedance is an important parameter, which influences the
current distribution. All converters must have equal supply impedance.
Powering the AC fans in R7 and R8
See Appendix B Powering the AC fans of R7 and R8 for more information.
Brake resistor circuit
Figure 3 presents an example of a three converter system. Both internal and
external brake choppers are shown.
Only one brake chopper is allowed to be used.
When an internal chopper is used, contactor K1 disconnects both poles of the brake
resistor when a fault is detected. An auxiliary contactor of the contactor K1 is used to
trip the drive on a START INHIBIT fault when the brake resistor overheats.
When an external chopper is used, contactor K3 disconnects both poles of the brake
resistor when a fault is detected. When the brake resistor is disconnected the whole
system will trip on a OVERVOLTAGE fault.
Connecting the contactor of the resistor circuit
• Wire an output relay of the RMIO board to control the contactor. The default value
is that the contactor is closed during normal operation and when the power is off.
• Set the output relay to open when drive trips on a FAULT or BC SHORT CIRCUIT.
See appropriate drive parameter from parameter group 14.
Warning! Application macro change resets the settings. Restore the settings to
correct values after the macro change.

Wiring

Phase loss guard
It is recommended to use phase loss guard in the input supplies of all of the
converters. If phase loss guard is not used and the fuse of one of the input supply
phases blows, the semiconductors of the converters may be overloaded and
damaged.
READY signals
To ensure that all of the DC links have been charged before the system is started,
the READY signals of the converters must be wired together. If this is neglected, the
charging resistor can be damaged.
Wiring the READY signals
• Wire together the READY signals of all the converters connected to the main
supply and the START INTERLOCK signals of all of the converters not connected
to the main supply. An example is presented in figure 4 below.
Wiring
23

Wiring
24
Start-up
• It is recommended to set parameter 99.04 MOTOR CTRL MODE to DTC and to
adjust parameters 20.11 P MOTORING LIM and 20.12 P GENERATING LIM to
limit the maximum power. The braking power given by equation 3 can also be
used as the parameter value of 20.12 P GENERATING LIM.
• When brake chopper is used, set parameter 27.08 BC CTRL MODE to COMMON
DC. This activates the chopper when the DC voltage is high. Also the parameter
20.05 OVERVOLTAGE CONTROL must be disabled from all of the converters
separately.
• All converters must be in the READY state before starting. See section READY
signals for instuctions on how to connect the READY signals.
• Switch on the possible DC contactors based on Table 1 after all of the DC links
are charged and the converters are in the READY state, i.e. when the power is on
and no faults appear.
Note: The parameter settings mentioned above apply to ACS800 Standard
Application Program.
Note: With ACS800-11, line-side converter parameter 16.15 I/O START MODE must
be set to DI2 LEVEL (= IGBT supply unit starts modulating always when the RMIO
control board is powered). If parameter 16.15 setting is other than DI2 LEVEL,
the charging resistor can be damaged.
Always check the setting of parameter 16.15 I/O START MODE after software
update, macro change or control board replacement!
See ACS800-11 Hardware Manual for information on how to change the line-side
converter parameters with control panel.

Appendix A Charging circuit capacity
The total power of the common DC system Pout.tot is higher if the smallest converter
is not connected directly to the main supply. To determine whether it is possible to
leave some converters unconnected, the total charging energy of the DC capacitors
and associated inrush currents must be analysed.
Frame sizes R...R4
In frame sizes R2...R4 the charging resistor is in series with the DC capacitors and
all DC buses are charged via their own resistors despite of the main supply
connection. The inrush current remains at an acceptable level, if the maximum
number of unconnected converters per one connected converter is five.
Note: Always connect the biggest converter to the main supply.
Frame sizes R5...R8
In frame sizes R5...R8 the charging circuit is in parallel with the input bridge. The
charging resistor of the connected converter limits the number of the unconnected
converters. The charging circuit of the connected converter must be able to
withstand the total charging energy Etot, i.e.
equation 7
E rconnected > Etot
Erconnected = charging resistor’s energy pulse withstand of the connected
converter
The charging energy of the DC link capacitors of a single converter can be
calculated with equation 8.

The total charging energy of the system Etot is calculated by summing the energies
of single converters.

Note: Always connect the biggest converter to the main supply. If the charging circuit
of the biggest converter is not capable of delivering the demanded charging energy,
connect also the next biggest converter to the main supply.
Example 4
The DC buses of three converters ACS800-0060-3 (R5), ACS800-0120-3 (R6) and
ACS800-0170-3 (R7) are connected together. The main supply voltage is 400 V. The
total charging energy of the capacitors is

E tot = --- ⋅ ( 2400uF + 4700uF + 5700uF ) ⋅ ( 1.35 ⋅ 400V ) ⋅ 10 = 1866J
2
The charging resistor of the ACS800-0170-3 (R7) is able to withstand the whole
charging energy, Etot = 1866 J < Er = 5600 J.
Example 5
The DC buses of converters ACS800-0120-5 (R6), ACS800-0260-5 (R7) and
ACS800-0400-5 (R8) are connected together. The main supply voltage is 500 V. The
total charging energy of the capacitors is

–6
E tot = --- ⋅ ( 4700uF + 5700uF + 10800uF ) ⋅ ( 1.35 ⋅ 500V ) ⋅ 10 = 4829J
2
Even if the charging resistor of the ACS800-0260-5 (R7) is able to withstand the
whole charging energy, Etot = 4829 J < Er = 5600 J, the biggest converter
ACS800-0400-5 (R8) is connected to the main supply.

Example 6
The DC buses of two ACS800-0120-5 (R6) and four ACS800-0260-5 (R7) are
connected together. The main supply voltage is 500 V. The total charging energy of
the DC link capacitors is

–6
E tot = --- ⋅ ( 2 ⋅ 4700uF + 4 ⋅ 5700uF ) ⋅ ( 1.35 ⋅ 500V ) ⋅ 10 = 7335J
2
Etot exceeds the energy pulse withstand of the ACS800-0260-5 (R7) charging circuit.
Charging resistors of two ACS800-0260-5 (R7) are able to withstand the charging
energy, Etot = 7335 J < Er = 2 ⋅ 5600 J.

Appendix B Powering the AC fans of R7 and R8
If the supply of frame size R7 or R8 is not connected to the main supply, the AC fan
must be powered separately.
Feed the primary of the fan circuit transformer with the converter’s nominal main
supply voltage, V- and W-phases, via the built-in fan circuit. The original cables
between the busbars and the fuses have to be removed. The feeding cable must be
protected against short circuits despite of the used built-in fuses.
The fuse locations are shown in the following picture.
