When the frequency command decreases
below (
Pr. 139 - Pr. 159
) after operation is
switched from inverter operation to bypass
operation, the inverter automatically
switches operation to inverter operation
and operates at the frequency of frequency
command.
When the inverter start command (STF/
STR) is turned off, operation is switched to
inverter operation also.

When the inverter start command (STF/
STR) is turned off after operation is
switched from inverter operation to bypass
operation, operation is switched to inverter
operation and the motor decelerates to
stop.
