(3) Example circuit 3 Motor power shutdown(Stop 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 driver power supply and the M24V and EMG terminal of the power supply plug.
(Circuit example) The figure below shows the stopped state.

(The 3
rd
driver)
Warning
(1) Relay contacts should be made between the 24 VDC driver 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 driver 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 RLS terminal when there is a necessity to shut down the motor drive
power (M24V) externally.
Because the BK RLS terminal is connected with M24V in the driver, the electric actuator may do
unexpected operation. Please turn off the EMG terminal when energizing to the BK RLS terminal
at motor drive power is OFF.
