External Input/Output Circuit

②

（1）EMG-IN (Emergency Stop Input) (CN1 : Pin1, Pin9)

When the E800Z is shipped from the factory, a shorting pin is installed

between pins 1 & 9.

Before the Emergency Stop Input can be used the shorting pin must

be removed.

When the circuit between Pins 1 and 9 is completed, the safety relay is

closed and power is supplied to the motor. When the circuit between

Pins1 and 9 is open, the relay contacts are opened and the power

supply to the motor is interrupted.

disconnected power can

relay contacts are not closed.

When the Emergency Stop Signal system is to be connected to a

machine

s interlock safety system remove the shorting pin shown in

and connect this line to the interlock safety switch.

（2）CON ERR (Motor Cord Disconnect Output) (CN1:Pin2, Pin10)

When the motor cord is disconnected or the AC Power Source is

disconnected or shut off, the Transistor Output of the Photo Coupler is

OFF. When the motor cord is connected and the AC Power Source is

connected and the Power Switch is ON, the Transistor Output is ON.

the motor is disconnected.

When there is continuity between PIN3 and PIN11 ON(Closed) Safety Relay is

When AUTO mode is being used,output transistor is ON(closed).

When incoming power supply is active, output transistor is ON(closed).
