Emergency Stop Signal Input
Pin No. 1 - 9
This signal is a switched DC+24V output.
Please use a separate power source that is capable of applying DC+24V
±
10%,
50mA. Refer to Fig. 40 below for connections.
Normal Operation circuit is ' ON (Closed) ' Emergency Stop circuit is ' OFF (Open) '.
If the Emergency Stop Signal is ' OFF (Open) ' the Safety Relay is OFF and the power supply to the motor is
interrupted and the motor stops.
