7.3 Allen-Bradley/Electro-Craft Drives with GS/X Actuator (M Connector Option) SYSTEM OVERVIEW GS Series Actuator Status J5 + DC Bus - J2 100-120 VAC 50/60 Hz L2/N OR J5 (Same Connections) J5 J2 J1 L1 Allen-Bradley or Electro-Craft RS-232 Cable 9101-1372-xxx R J1 S Motor T R S T J2 AC Power J1 9101-1366-XXX BC1-AC-XXX (Brake or Limit Switch) Allen-Bradley or Electro-Craft 9101-1391 24 VDC Supply Clamp exposed motor cable shield to the chassis Ground terminal PC6-MC-XXX (GS20 & 30), PC7-MC-XXX (GS40/45) or PC3-AC-XXX (GS60) Controller (Optional) Dangerous voltages exist so use extreme caution when operating this equipment. Sufficient energy remains in the DDM-XXX to cause motion even with the power removed. To verify that the equipment is safe, insure that the voltage across the DC+ and DC- terminals is at 0VDC. At startup, reduce the positive and negative current to below the rated current, such that accelerating torque is limited, until proper control is verified. SETTING UP THE DDM-XXX DRIVE TO RUN EXLAR GS/X SERIES ACTUATORS In order to program the drive to run the Exlar actuators, the motor parameter files provided by Exlar must be loaded into the motor directory, which by default is named “c:\brudrive\motordir”. Once the motor files are loaded, the following steps will set up the DDM-XXX drives to run the Exlar actuators: 1. 2. 3. 4. 5. 6. 7. 8. Connect the serial cable from the PC to J5 of the DDM-XXX. With the motor power cable disconnected from the motor, apply power to the DDM-XXX. Double click on the Ultra Master or BRU Master icon to start the program. Following the upload of drive information, click on the Drive Setup icon. Click on the down arrow for the motor model and select the appropriate Exlar actuator model number. The warnings generated after changing the motor are normal. The motor parameters are now downloaded into the drive and configuration for the motor is complete. Power down the drive and reconnect the motor cable. GS/X Manual.doc PN: 10278 Rev.

Changes to motor parameters require the advanced option for BRU Master or Ultra Master. Add /a to the command line of shortcut for the BRU Master or Ultra Master software to enable the advanced option. These Parameters and others specific to each motor winding are included in the motor file listed in the table in section 7.0. (2) Set to “yes” if TS+ and TS- from the motor cable are connected to J2 pins 19 and 20. (3) Voltage is 0 – peak of sinusoid, measured phase-to-phase (4) Current is 0 – peak of sinusoid CABLES FOR A-B / E-C DDM-XXX DRIVE AND GS/X SERIES ACTUATORS (M CONNECTOR OPTION) Refer to the diagram at the beginning of Section 7.4. The required cables are identified in the table below. An Exlar cable must be used for the brake/limit switch option and motor power on the GS/X Series actuators. AllenBradley / Electro-Craft does not offer a version of this cable.
