Caution
For driver input power supply (24 VDC) use a power supply with a capacity not less than the
“momentary maximum power” of the electric actuator spedfications. Do not use “inrush current
restraining type” power supply.
(2) Wiring of the stop switch
By connecting 24V to EMG, motor becomes operable. Without connect the 24V to EMG, motor does not
move. Stop switch must be installed by the user to stop the electric actuator in abnormal situations.
Please refer to
“5.4 Stop circuits”
for examples of how to wire stop switches.
Caution
The Servo is not ON unless a voltage of 24 VDC is applied to the EMG terminal.
(3) Wiring of the lock release
Install an unlocking switch for adjustment or recovery during an emergency of the electric actuator with
lock. The switch (24 VDC, Contact capacity: 0.5A or more) should be obtained separately.
One terminal of the lock release switch should be connected to the 24 VDC power supply and the other
should be connected to the BK RLS terminal. When this is switched on, the lock will be released forcibly.
Power supply plug Lock release switch
Caution
If the electric actuator is a non-lock type, it is not necessary to wire the BK RLS terminal.
Do not supply power to the BK RLS (lock release) during normal operation.
The 24 VDC supply to the BK RLS (lock release) is only required for the adjustment and the
recovery in the emergency.
After the wiring of the power supply plug is completed, connect it to the CN1 connector of the driver.
Please refer to
“5.3 Wiring of power supply plug”
for how to wire the power supply plug.
