Fault tracing
107
A2026 INPUT PHASE
LOSS
(programmable
fault function 3016)
Intermediate circuit DC voltage is
oscillating due to missing input
power line phase or blown fuse.
Alarm is generated when DC
voltage ripple exceeds 14% of
nominal DC voltage.
Check input power line fuses.
Check for input power supply imbalance.
Check fault function parameter setting.
CODE CAUSE WHAT TO DO
A5011 Drive is controlled from another source. Change drive control to local control mode.
A5012 Direction of rotation is locked. Enable change of direction. See parameter 1003
DIRECTION.
A5013 Panel control is disabled because start inhibit is active. Deactivate start inhibit and retry. See parameter 2108
START INHIBIT.
A5014 Panel control is disabled because of drive fault. Reset drive fault and retry.
A5015 Panel control is disabled because local control mode
lock is active.
Deactivate local control mode lock and retry. See
parameter 1606 LOCAL LOCK.
A5019 Writing non-zero parameter value is prohibited. Only parameter reset is allowed.
A5022 Parameter is write protected. Parameter value is read-only and cannot be changed.
A5023 Parameter change is not allowed, when drive is running. Stop drive and change parameter value.
A5024 Drive is executing task. Wait until task is completed.
A5026 Value is at or below minimum limit. Contact your local ABB representative.
A5027 Value is at or above maximum limit. Contact your local ABB representative.
A5028 Invalid value Contact your local ABB representative.
A5029 Memory is not ready. Retry.
A5030 Invalid request Contact your local ABB representative.
A5031 Drive is not ready for operation, e.g due to low DC
voltage.
Check input power supply.
A5032 Parameter error Contact your local ABB representative.
