Nine types of functions can be selected for the multi-function input terminals
No. 7, 8, 9 (SW1, SW2, SW3). Refer to the following explanation and use
these functions effectively.
1. Multi-speed SW function (Parameters: P19, P20, P21/Data setting value: 0)
Eight types of frequencies can be selected, changed and controlled with the three
switch signals SW1, 2 and 3.
(Speed 1: Parameter P09 setting signal, Speeds 2 to 8: Parameter P32 to P38 set
frequency)

∗
When using one switch input for this function, there will be two speeds, and when
two switches are used, there will be four speeds. (Example: When only SW1 is used,
the speeds will change between speed 1 and speed 2. When SW1 and SW2 are
used, the speeds will change between speeds 1 and 4.)
∗
If "000" is set for the speeds 2 to 8 frequency (parameters P32 to P38), the inverter
will stop (0V stop) when that multi-speed frequency is selected.
2. Reset input function (Parameters: P19, P20, P21/Data setting value: 1)
This function resets the fault stop state from an external device when the inverter trips
(stops) with a fault.

When starting/stopping with the operation
panel, operation is restarted with the
panel after resetting. The operation will
not resume just by resetting.

The fault trip can also be reset by turning
the run signal OFF (stopping).
