3. Function Explanation
Motor operation can be switched from 50Hz commercial power
operation to inverter operation without stopping the motor by
switching the external digital input signal.
Motor operation can be switched from 60Hz commercial power
operation to inverter operation without stopping the motor by
switching the external digital input signal.
Switching operation between line and inverter(50Hz) [SW50] :15
This function allows the data to be changed only when an
external signal is being input, thereby making it difficult to
change the data.
NOTE:
If a terminal is set to value 19, the data becomes unable to be
changed. To change the data, turn on the terminal and change the
terminal setting to another number.
The PID control can be disabled by an external digital input
signal.
The analog input (terminals 12 and C1) can be switched
between normal and inverse operations by an external digital
input signal.
When a magnetic contactor is installed on the output side of
the inverter, the contactor opens at the time of a momentary
power failure, which hinders the reduction of the DC circuit
voltage and may prevent the detection of a power failure and
the correct restart operation when power is recovered. The
restart operation at momentary power failure can be per-
formed effectively with power failure information provided by
an external digital input signal.

When the digital input signal goes off, 50 or 60 Hz is output according
to the set value input signal after the restart waiting time following a
momentary power failure (function code H13). The motor is then
directed to inverter operation.
When an operation command is input (on), the output fre-
quency can be increased or decreased by an external digital
input signal.
The change ranges from 0 to maximum frequency. Operation
in the opposite direction of the operation command is not
allowed.
