How to Calculate Accelerating and Decelerating Time (Example)
Question : Wish to accelerate and decelerate the actuator in between 5 L/min. and 25 L/min. in the use of
proportional flow control valve model EFG-02-30-31 .
In such case, what are the maximum and minimum time adjustable for the acceleration and deceleration?
※
※
Answer : The input current for EFG-02-30-31 at the flow rate of 5 L/min. and 25 L/min. can be obtained
respectively from the chart below. The chart shows :
Input current at 5 L/min.
300mA
Input current at 25 L/min.
520mA
Then, the difference between the above two can be obtained with the following formula :
520 mA -300 mA = 220 mA
While, the specification for the model AME-T-S shows the amplifier’s gradient for acceleration or
deceleration as being between 0.05 s/100 mA and 1.0 s/100 mA (which means that the minimum time is
0.05 seconds and the maximum time is 1.0 second for every 100 mA variation).
Therefore, the minimum and maximum adjustable time can be obtained as follows :
220 mA x 0.05 seconds = 0.11 (Minimum)
100 mA
220 mA x 1.0 seconds = 2.2 second (Maximum)
100 mA
The result above are as illustrated on the below :

Power Amplifiers For 10Ω - 10Ω Series Control Valves
These power amplifiers can drive two solenoid of 10Ω load simultaneously
or separately, and the control can be done in the same way even though the
object is separated by pressure system and flow rate system. Although the
display of control unit on the front panel is PRESS and FLOW , they are
exactly the same circuit, so there is no direction between the two system
when used.

For High Response Type Directional Flow Control Valves
The power amplifiers are used to drive the high
response type proportional electro-hydraulic
directional and flow control valves.
A compact AMN-L modl and a euro card type
AMB-EL model are available.
The single height [ 3U: 100x160 mm]
is employed for the euro card
size of the AMB-EL model.
