• During decelerating at momentary power failure "IPF2"
This parameter turns ON when Power Interruption Restart Mode Selection (F14) is 2 or 3, and the
Main Circuit DC Voltage falls below Continuous Running Voltage Level (H15) and the continuous
running state is established. This parameter turns OFF when power restores and the Main Circuit
DC Voltage becomes "the voltage set in H15 +10 V or higher."
This parameter turns ON even when Power Interruption Restart Mode Selection (F14) is 4 or 5 and
the Main Circuit DC Voltage falls below the undervoltage level. This parameter turns OFF when the
DC link bus voltage reaches "the undervoltage level +10 V or higher."
Parameter No.
