② 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.

③ Safety Relay Signal
CAUTION
If the Emergency Stop Function is not installed, the Emergency Stop Signal (EMG - IN) will not function.
If enabling the Emergency Stop Function, it is necessary to set parameter
Selection of Emergency Stop Function " section.)
Pin No. 3 - 1 1 , 4 - 1 2
・ The Safety Relay will be ON or OFF depending on the state of the " Emergency Stop (Pin No.
EMG - INA - Pin No. 9 : EMG - INB) ".
・ When there is continuity between Pin No.
No. 4 (SAFE - 2 A) and Pin No. 12 (SAFE - 2 B) the motor is off. If there is no continuity between these
pairs of pins then the system is operating normally.
・ If the Emergency Stop Signal is ' OFF (Open) ' the Safety Relay will be ' OFF (Open) ' and the motor
power will be interrupted and the motor will stop.
・ If the (NO) Normally Open contacts of the Safety Relay are welded together by an over load or short
circuit the (NC) Normally Closed contacts separation are maintained with more than 0 . 5 mm spacing
by the relay's recoil mechanism.
・ The voltage / current speci cations of Pin No.
Applied Voltage (V) ≦ DC+ 30 V
