6-13
Pr-77 Low Level Sensor Trip Time 6-14
Er-05 (Arm Short Trip-tASH )
Cause
ㆍ
In case acceleration/deceleration time is excessively short comparing to load inertia
ㆍ
Up/Down short circuit of IGBT
ㆍ
Output short circuit
ㆍ
Motor damage from fire and insulation defect
Reaction
ㆍ
Expand rising time (dr-22).
ㆍ
Check motor damage from fire and insulation fault.
ㆍ
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.

6-18 Rising Time dr-22
Er-06 ( H/W Over Current Trip-tOC )
Cause
ㆍ
In case acceleration/deceleration time is excessively short comparing to load inertia
ㆍ
When drive restarts during free run of motor
ㆍ
Drive damage from fire
Reaction
ㆍ
Adjust the acceleration/deceleration time.
ㆍ
Check if the drive capacity is suitable for motor capacity.
ㆍ
Start the pump after the motor stopped.
ㆍ
Check load, motor, and output wiring.
ㆍ
If the same alarm occurs, please contact A/S center.
