SECTION 6: SYSTEM CHECKING
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 all power to the drive before performing work on parts mechanically
coupled to the motor.
If installation and operating instructions have been carefully followed, this unit should
perform correctly. If the motor fails to step properly, the following checklist will be
helpful in locating and correcting the problem.
In General
Check all installation wiring carefully for wiring errors or poor connections.
Ensure that the proper voltage levels are being supplied to the unit.
Be sure that the motor is a correct model for use with this unit.
Specifically
IF MOTOR DIRECTION (CW, CCW) IS REVERSED, Check For:
Reversed connections to the Motor Connector. Reversing the phase A or the phase B
connections reverses the direction of motor rotation.
IF THE MOTOR MOTION IS ERRATIC, Check For:
Supply voltage out of tolerance.
Proper motion parameters (low speed, acceleration/deceleration, jog speed, home
speed and feed rate). Set parameters on controller supplying pulse input to drive.
Filter capacitor missing or too low in value.
IF TORQUE IS LOW, Check For:
All Windings Off active
Correct current setting.
Improper supply voltage.
IF "FAULT" INDICATOR IS NOT LIT, Check For:
Improper motor wiring.
Grounded or shorted wiring to the motor or shorted motor.
Improper motor type or incorrect Current Select switch setting
If a malfunction occurs that cannot be corrected by making the preceding checks, contact
