(3) Example circuit 3 - Motor power shutdown (relay contact (2))
If there is a
necessity to have circuit to shutdown the motor power externally, relay contacts should be
made between the 24VDC controller power supply and the M24V and EMG terminal of the power supply
plug.
The relay must be a safety relay or monitored by a safety relay.
Warning
1. Relay contacts should be made between the 24VDC controller power supply and the M24V and
EMG terminal of the power supply plug. The 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. Do not energize to the BK R LS terminal when there is a necessity to shutdown the motor drive
power (M24V) externally.
Because the BK RLS terminal is connected with M24V in the controller, the actuator may do
unexpected operation. Please turn off the EMG terminal when energizing to the BK RLS terminal at
motor drive power is OFF.
