Wiring for Emergency Shutoff Function

Slide Switch (SW1) Setting
The built-in slide switch is used to enable or disable the emergency shutoff function.
This function is disabled by factory default.
For the location of the slide switch, refer to the figure below.
For how to remove the control circuit terminal block, refer to Removing Control Circuit Terminal Block on
page 2-12.
Emergency Shutoff Function
This function is intended to shut off the inverter output (stop switching the main element) via only the
multi-function input terminal of the hardware circuit without use of the built-in CPU software.
To enable this function, set the slide switch SW1 lever in the inverter to ON. By factory default, slide
switch SW1 is OFF (function disabled).
When this function is enabled, the multi-function input terminals S1 and S3 are dedicated for this
function. No other function can be allocated to these terminals. If another function is allocated, it is
automatically disabled, and terminals S1 and S3 are changed to the emergency shutoff terminals.
