Slide Switch (SW1) Settings
The built-in slide switch is used to enable or disable the emergency shutoff function. (Factory
Default: Disabled)
* For the location of the slide switch, refer to (page 2-12).
Emergency Shutoff Function (Factory Default: Disabled)
• This function is intended to turn off the Inverter output (stop switching the main element) via only
the multi-function input terminal of the hardware circuit without going through the CPU software.
* This function stops switching of the main element.The circuit is not electrically turned off. While the
power supply is ON, do not touch the Inverter terminals and power cable (e.g. motor cable). Doing
so may result in electric shock, injury or ground fault.
• When this function is enabled, the multi-function input terminals S1 and S3 are exclusively used
for this function. No other function can be allocated to these terminals. If another function has been
allocated, it will automatically be disabled, and terminals S1 and S3 are changed to the emergency
shutoff terminals.
Function of multi-function input terminal S1
Reset signal (RS) / NO contact (Fixed)
This signal is used to reset the Inverter, and to reset the emergency shutoff trip [ E37.* ].
Function of multi-function input terminal S3
Emergency shutoff signal (EMR) / NC contact (Fixed)
This signal is used to turn off the Inverter output without using the built-in CPU.
With this signal input, the Inverter activates an emergency shutoff trip [ E37. * ].
