Operation
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.
