Frequency setting by external terminals

PARAMETERS
REMARKS
During Jog operation or PID control operation, the remote setting function is invalid.
⋅ 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 selecting this function, re-set the maximum frequency according to the machine.
