Frequency setting by external terminals Parameter
6 - 58
During jog operation or PID control operation, the remote setting function is invalid.
Set frequency = 0Hz
●
Even when the remotely-set frequency is cleared by turning on the RL (clear) signal after
turn off (on) of both the RH and RM signals, the inverter operates at the remotely-set
frequency stored in the last operation if power is reapplied before one minute has elapsed
since turn off (on) of both the RH and RM signals.
●
When the remotely-set frequency is cleared by turning on the RL (clear) signal after turn off
(on) of both the RH and RM signals, the inverter operates at the frequency in the remotely-
set frequency cleared state if power is reapplied after one minute has elapsed since turn off
(on) of both the RH and RM signals.

CAUTION:
When Pr. 59 is set to "1" the motor will restart automatically after a power failure if
there is an active rotation direction signal.
