Safety stop function
The terminals related to the safety stop function are shown below.
In the initial status, terminals S1 and PC, S2 and PC, and SIC and SD are respectively shorted with
shorting wires. To use the safety stop function, remove all the shortening wires, and then connect
to the safety relay module as shown in the following connection diagram.
At an internal safety circuit failure, the operation panel displays one of the faults shown on page
Use the terminal SO to output a fault and to prevent restarting of the inverter. The signal cannot
be used as safety stop input terminal to other devices.
