<Setting>
●
Set the frequency to switch inverter operation to bypass operation. Inverter operation is performed
from a start until P.249
is reached, and when the output frequency is at or above P.249, inverter
operation is automatically switched to bypass operation. If set 99999 to P.249, without automatic
switchover.
●
If the value of P.250 is not 99999, valid during automatic switchover operation
(Pr.249
≠
99999)
.
When the frequency command decreases below (Pr.249 - Pr.250) 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.
●
If the value of P.250 is 99999, valid during automatic switchover operation (Pr.249
≠
99999).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.
