Automatic switchover
frequency range
0~10.00Hz: When the inverter start reference (STF/STR) is
turned off after the operation is changed from inverter opera-
tion to commercial power supply operation, the operation will
be changed to the inverter operation.
99999
99999: When the inverter start reference (STF/STR) is turned
off after the operation is changed from inverter
operation to commercial power supply operation, the
operation will be changed to the inverter operation
and the motor will decelerate until it stops.

1: No undervoltage avoidance (Ifan undervoltage or power
failureoccurs, the motordecelerates to a stop.)
2: No undervoltage avoidance (If an undervoltage or power
failure occurs, the motor decelerates to a stop. Motor
re-accelerates if the power restores during the decelera-
tion to stop.)
11: Undervoltage avoidance (If an undervoltage or power
failure occurs, the motor decelerates to a stop.)
12: Undervoltage avoidance (If an undervoltage or power
failure occurs, the motor decelerates to a stop. Motor
re-accelerates if the power restores during the decelera-
