Operation details
Without auto search
With auto search
*1
0: Trip An alarm is output when an overvoltage or overcurrent is detected, the inverter
output is cut of
f, and the motor falls in a free-run state.
4: Restart based on pull-in
frequency
If an overvoltage or overcurrent is detected, the inverter output is cut off, and the
motor falls in a free-run state.
During recovery from overvoltage or
overcurrent, restart is performed from
the pull-in frequency. Select the pull-in
frequency in E152.
During recovery from overvoltage or
overcurrent, auto search is performed,
the motor speed is estimated, and re-
start is performed from the frequency.
*1. With auto search is selected when Enable auto search for idling motor speed at starting “STM” is ON, or
H09 (d67) = 2.
When a motor control method with speed sensor is selected, restart is performed from the motor speed de-
tected by the speed sensor. In the case of a motor control method without speed sensor, restart is per-
formed from the estimated speed.
Additional Information
When using vector control without speed sensor, do not use restarting from the pull-in frequen-
cy (Starting Frequency Selection at Frequency Pull-in Restart (E152)). If you select starting
from pull-in frequency, normal start may not be performed, or the device may be damaged.
Use the retry function to recover from overvoltage or overcurrent.
