(3) Example circuit 3 - Motor power shutdown
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 M 24V and EMG terminal of the power supply
plug.
(Circuit example: The figure below shows the stopped state.)
Warning
(1) Relay contacts should be made between the 24 VDC controller power supply and the M 24V 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 (M 24V) is
disconnected. The controller cannot recognize the correct origin point if a return to origin instruction
is made with the motor drive power (M 24V) 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 (M 24V), 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 (M 24V) externally.
Because the BK RLS terminal is connected with M 24V in the controller, 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.
