[3] Power Supply and Emergency Stop Release
(1) MEC Mode 1 (CP, MP, EMG)·························[Refer to 3.4.3 Circuit Diagram]
1) Supply the control power (CP, CP_GND), first.
2) Secondly, turn ON the motor power source (MP, MP_GND) and the emergency stop signal
EMG at the same time. Do not attempt to turn ON the emergency stop signal EMG prior to
the motor power source.
The controllers get into the servo-on status by the emergency stop signal EMG being ON.
For an actuator equipped with a brake, the brake is released by the servo being turned ON.
3) If the emergency stop signal EMG turns OFF, the servo also turns OFF. Have the motor
power (MP, MP_GND) cut off at the same time. Do not attempt to cut off the motor power
(MP, MP_GND) prior to the emergency stop signal EMG being turned OFF.
For an actuator equipped with a brake, the brake becomes in operation by turning the servo
OFF.
(2) MEC Mode 2 (CP24V, MPO, MPI, EMG(-))···[Refer to 3.5.3 Circuit Diagram]
1) Supply the control power (CP24, GND), first.
2) Secondly, turn ON the motor power source (MPO, MPI) and the emergency stop signal
EMG(-) at the same time. Do not attempt to turn ON the emergency stop signal EMG(-) prior
to the motor power source.
Have a jumper in advance between MPO and MPI for the built-in drive cutoff relay type.
Turn ON the motor power supply (MPO and MPI) and the emergency stop signal EMG(-) at
the same time for the externally mounted drive cutoff relay type.
The controllers get into the servo-on status by the emergency stop signal EMG(-) being ON.
Also for an actuator equipped with a brake, the brake is released by the servo being turned
ON.
3) If the emergency stop signal EMG(-) turns OFF, the servo also turns OFF. Conduct a cutoff of
the motor power supply (MP0 and MP1) at the same time.
Do not attempt to turn OFF the motor power supply (MPO and MPI) before the emergency
stop signal EMG (-) is turned off for the externally mounted drive cutoff relay type.
For an actuator equipped with a brake, the brake becomes in operation by turning the servo
OFF.
