SECTION 8: TROUBLESHOOTING
WARNING
Motors connected to this drive can develop high torque and
large amounts of mechanical energy.
Keep clear of the motor shaft, and all parts mechanically linked
to the motor shaft.
Turn off the power to the drive before performing work on
parts mechanically coupled to the motor.
If installation and operation instructions have been followed care-
fully, this unit should perform correctly. If motor fails to step properly,
the following checklist will be helpful.
In General:
• Check all installation wiring carefully for wiring errors or poor con-
nections.
• Check to see that the proper DC voltage level is being supplied to
the unit.
• Be sure the motor is compatible for use with this unit.
8.1 IF MOTOR DIRECTION (CW, CCW) IS REVERSED, CHECK:
Connections to the J2 Motor Connector are reversed.
8.2 IF THE MOTOR MOTION IS ERRATIC, Check:
Low filter capacitor
Input pulses not of proper level or width.
Supply voltage out of tolerance.
Motion parameters (base speed, high speed, acceleratin/decel-
eration) may need adjustment.
8.3 IF TORQUE IS LOW, Check:
AWO (All Windings Off) active or REDUCED CURRENT active.
Improper supply voltage.
If a malfunction occurs that cannot be corrected by making these
correction, contact Superior Electric.
