[3] Power Supply and Emergency Stop Release (CP24, MPI, MPO, EMG(-))
[Refer to 3.3.3 Circuit Diagram]
(1) Built-in Drive Cutoff Relay Type (Model: RCB-CV-ƑƑƑ)
1) Supply the power (CP24, GND), first.
2) Secondly, turn ON the motor power source and the emergency stop signal at the same
time. Do not attempt to turn ON the emergency stop signal prior to the motor power
source.
Jumper MPI and MPO in advance (is already jumpered at the delivery). By releasing the
emergency stop (turning ON EMG(-) Signal), built-in relay turns ON and power is
supplied to the driving source.
3) Once the emergency stop signal EMG(-) is turned OFF, a cutoff of the motor power
supply by the built-in relay is conducted at the same time as the servo being turned OFF.
Do not attempt to cut off the motor power supply (MPI and MPO) in advance to the
emergency stop signal EMG(-) being turned OFF.
(2) External Drive Cutoff Relay Type
(Model: RCB-CVG-ƑƑƑ)
1) Supply the power (CP24, GND), first.
2) Secondly, turn ON the motor power source and the emergency stop signal at the same
time. Do not attempt to turn ON the emergency stop signal prior to the motor power
source.
Connect a contact for the cutoff relay between MPI and MPO and turn it ON at the same
time as releasing the emergency stop (turning EMG(-) Signal ON).
3) If the emergency stop signal EMG turns OFF, the servo also turns OFF. Have the motor
power (MPI, MPO) cut off at the same time. Do not attempt to cut off the motor power
(MPI, MPO) prior to the emergency stop signal EMG being turned OFF.


[4] Time Constant for Control Signal Input
For the input signal for control of this controller, it is set to 6ms of input time constant to prevent
an error operation due to chattering or noise from the next page and later.
Therefore, input each input signal for 6ms or more (Note) continuously. The signal cannot be
identified if it is less than 6ms.
