Before applying power (all models)

ATTENTION: If the motor or drive does not perform

as described, disconnect the AC line voltage

immediately. Refer to the Troubleshooting section,

page 67, for further assistance.

• Set LINE VOLTAGE SELECT switches SW501 and

SW502 to either 115V or 230V to match the AC line

voltage.

• Set ARMATURE VOLTAGE SELECT switch SW503 to

either 90V or 180V to match the maximum armature

voltage.

• Set SIGNAL SELECT switch SW504 to CURR if using

a 4-20 mADC current signal; set it to VOLT if using a

0-10 VDC voltage signal or the speed adjust

potentiometer.

• Verify that no conductive material is present on the

printed circuit board.

• If using a 90 VDC or 130 VDC motor with 230 VAC

line voltage, derate the nameplate motor speed and

torque by at least 30%. The form factor will increase

beyond the typical value, causing increased motor

heating. Contact the factory for details.
