Example circuit 3 - Motor power shutdown (Relay contact (2))
If there is a necessity to have circuit to shut down the motor power externally, relay contacts should be made
between the 24 VDC controller power supply and the M24V and EMG terminal of the power supply plug.
Warning
(1) Relay contacts should be made between the 24 VDC controller power supply and the M24V and EMG
terminal of the power supply plug. The electric actuator may make unexpected movement.
(2) When at the same time to OFF EMG and the power, For the inertia of the load, you might have to take
time until the motor stops.
(3) Do not perform return to origin (SETUP input ON) when motor drive power (M24V) is disconnected.
The controller cannot recognize the correct origin point if a return to origin instruction is made with the
motor drive power (M24V) disconnected.
(4) If the electric actuator with lock is used vertically, delay in response of the brake may occur when
shutting off the motor power supply (M24V), and the moving part of the electric actuator may drop due
to the weight of the electric actuator itself.
(5) Do not energize to the BK R LS terminal when there is a necessity to shut down the motor drive power
(M24V) externally.
Because the LK RLS terminal is connected with M24V in the controller, the electric actuator may do
unexpected operation. Please turn off the EMG terminal when energizing to the LK RLS terminal at
motor drive power is OFF.
