2.6.5 Safety stop function
 Function description
The terminals related to the safety stop function are as follows.
*1 In the initial status, terminals S1 and PC and terminals S2 and PC are respectively shorted with shorting wires.) To use the safety stop function,
remove all the shorting wires, and then connect to the safety relay module as shown in the connection diagram.
*2 When any fault listed on the next page occurs in the internal safety circuit, the corresponding indication is shown on the operation panel.
NOTE
• Terminal SO can be used to display a fault indication and to prevent restarting of the inverter. The signal output from terminal
SO cannot be used to input a safety stop signal to other devices.
 Connection diagram
To prevent restart at fault occurrence, connect terminals SO and SOC to the reset button, which are the feedback input
terminals of the safety relay module.
*1 To avoid an electric shock hazard, install a magnetic contactor (MC) at the input side of the inverter.
