Terminal function description
For input of safety stop channel 1
Between S1 and PC
OFF: In safety stop mode
ON: Other than the safety stop mode
For input of safety stop channel 2
Between S2 and PC
OFF: In safety stop mode
ON: Other than the safety stop mode
-
Used for internal safety circuit failure detection and
alarm (open collector output).
Between SO and SOC
OFF: Internal safety circuit failure or alarm detected
ON: No internal safety circuit failure
Note: Terminal SO cannot be used for safety signals in a
safety system. Use terminal SO to output a fault
and to prevent restarting of the inverter.
Common terminal for terminal SO
