INDICATION
POSSIBLE CAUSE
CORRECTIVE ACTION
Motor has wrong
response to
Speed Command
Input common mode voltage may
be excessive.
Connect control input source common to control common to minimize
common mode voltage. Maximum common mode voltage at terminals
J1A-4 and J1A-5 is
±
15VDC referenced to chassis common.
Motor Will Not
Start
Not enough starting torque.
Increase Current Limit setting.
Start
Motor overloaded.
Check for proper motor loading.
Check couplings for binding.
Verify proper sizing of control and motor.
Control not in local mode of
operation.
Place control in local mode.
Incorrect Command Select
parameter.
Change Command Select parameter to match wiring at J1A and J1B.
Incorrect speed command.
Verify control is receiving proper command signal at J1A and J1B.
Motor Will Not
Reach Maximum
Speed
Max Output Speed parameter set
too low.
Adjust MAX Output Speed parameter value.
Speed
Motor overloaded.
Check for mechanical overload. If unloaded motor shaft does not rotate
freely, check motor bearings.
Improper speed command.
Verify control is receiving proper command signal at input terminals.
Verify control is set to proper operating mode to receive speed command.
Speed potentiometer failure.
Replace potentiometer.
Motor Will Not
Stop Rotation
MIN Output Speed parameter value
set too high.
Reduce MIN Output Speed parameter value.
Improper speed command.
Verify control is receiving proper command signal at input terminals.
Verify control is set to receive speed command.
