Valid during automatic switchover
operation (Pr. 139 ≠ 9999)
When the frequency command decreases
below (Pr. 139 - Pr. 159) after operation is
switched from inverter operation to bypass
operation, the inverter automatically
0 to 10Hz
switches operation to inverter operation
and operates at the frequency of frequency
command.
When the inverter start command (STF/
0.01Hz
9999
STR) is turned off, operation is switched to
inverter operation also.
Valid during automatic switchover
operation (Pr. 139 ≠ 9999)
When the inverter start command (STF/
STR) is turned off after operation is
9999
switched from inverter operation to bypass
operation, operation is switched to inverter
operation and the motor decelerates to
stop.
