■ Restart with frequency matching ([b001] = 02)
Detection of an instantaneous power failure or undervoltage error shuts off the inverter output,
and the motor runs free. After the power returns, the inverter performs an active frequency
matching restart at the frequency of the previous output interruption after the retry wait time set
in [b003]. At this time, no "Alarm [AL]" is output.
For details, refer to "9.7.3 Starting with Frequency Matching".
■ Decelerate and stop with frequency matching and then trip ([b001] = 03)
Detection of an instantaneous power failure or undervoltage error shuts off the inverter output,
and the motor runs free. After the power returns, the inverter performs an active frequency
matching restart at the frequency of the previous output interruption after the retry wait time set
in [b003], then decelerates the motor to stop and outputs an "Alarm [AL]".
For details, refer to "9.7.3 Starting with Frequency Matching".
■ Active Frequency matching restart ([b001] = 04)
Detection of an instantaneous power failure or undervoltage error shuts off the inverter output,
and the motor runs free. After the power returns, the inverter performs an active frequency
matching restart after the retry wait time set in [b003]. At this time, no "Alarm [AL]" is output.
For details on active frequency matching restart, refer to "9.7.4 Starting with Active Frequency
Matching".
The inverter decelerates the motor
to stop after active frequency
matching is performed, and
"Undervoltage error [E09]" occurs
