Troubleshooting

Name
Description
Possible Causes & Corrective Action
MAX FLT
RETRIES
(alarm)
[F89]
The drive has reached the maximum
allowable automatic drive resets.
Check Parameter Setting
Check that Fault Reset SRC (C1) is set
correctly
Check that the Flt Reset / Hour (A1) and
Flt Reset Delay (A1) are set correctly.
Increase the amount of allowable Flt
Resets / Hour (A1) .
Shut Down Problem
Resolve the issue(s) that is /are causing
the drive to fault.
Look in the FAULT HISTORY (F2) to
figure out which faults are causing the
drive to trip on a fault
MOTOR PHASE
FAULT
(PM)
[F61]
Speed feedback is backwards during
an Open-Loop Alignment
Phasing Problem
If the motor was running smoothly
immediately before the drive declared an
MOTOR PHASE FAULT
, Swap two
motor leads (e.g. U and W) to establish
proper phasing between absolute
position data (EnDat, serial) and motor.
Note: Swapping encoder leads is NOT
the same as swapping motor wiring. Do
not swap both motor phase leads and
encoder inputs at the same time.
Rotor is Not Moving when Open Loop
Alignment Commanded
Verify that the brake is picked and that
the car is properly balanced.
Verify that the motor contactor is closed
during the alignment.
Verify motor parameters in A5 menu.
Increase OL Align Scale (A5) to
overcome excessive static friction that
may exist in the elevator.
Rotor is rotating rough or jerky during
Open Loop Alignment
Increase the value for OL ALIGN SCALE
(A5) until the motor rotates smoothly
Run command was removed during Open
Loop Alignment
Verify the run command stayed active
while alignment was occurring
Note: This is only true when BEGIN
ALIGNMENT? = ON RUN
Encoder Problem
Encoder failure (replace encoder and
REALIGN the rotor).
Motor Parameter Problems
Verify values in Motor (A5) menu are
correct
