Frequency setting by external terminals
REMARKS
During Jog operation or PID control operation, the remote setting function is invalid.
Setting frequency is "0"
Even when
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
frequency in
frequency cleared state if power is
reapplied after one minute has
elapsed since turn OFF (ON) of
both the RH and RM signals.
When selecting this function, re-set the maximum frequency according to the machine.
