Er-05 (Arm Short Trip-tASH )
Cause
In case acceleration/deceleration time is excessively short comparing to load inertia
Up/Down short circuit of IGBT
Output short circuit
Motor damage from fire and insulation defect
Reaction
Expand rising time (dr-22).
Check motor damage from fire and insulation fault.
Conduct test run by separating motor line from the drive. If the same alarm occurs, it would be
an up/down short circuit of IGBT. For that case, please contact A/S center.
