This function switches the torque limit value set in
function codes F40 and F41, and E16 and E17 by an
external digital input signal.

Motor operation can be switched from 50Hz commercial
power operation to inverter operation without stopping the
motor by switching the external digital input signal.

Line operation to inverter operation (60Hz)
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.
WARNING
- After the LU(Low Voltage) trip is occurred and reset it,
the inverter will automatically restart because the
operation command is kept by internal sequence.
Accident may result.
When an operation command is input (on), the output
frequency 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.

Function selected
(when operation command is on)

Holds the output frequency.
off on
Increases the output frequency
according to the acceleration time.
on off
Decreases the output frequency
according to the deceleration time.
on on
Holds the output frequency.
There are the two types of UP/DOWN operations as
shown below. Set the desired type by setting the
frequency (F01 or C30).
The data "8: UP/DOWN 1" is valid only when the Motor

This function allows the data to be changed only when an
external signal is being input, thereby making it difficult to
change the data.

Allow data changes.
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.
