data
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 off, 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 over-
current, restart is performed from the pull-
in frequency. Select the pull-in frequency at
Starting Frequency Selection at Frequency
Pull-in Restart (301FHex-35Hex).
During recovery from overvoltage or over-
current, auto search is performed, the mo-
tor speed is estimated, and restart is per-
formed from the frequency.
*1. With auto search is Enable auto search for idling motor speed at starting “STM” is ON, or
3008Hex-0AHex(3014Hex-44Hex) = 1 or 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.
