PC Software <Optional>
RS232C type <RCM-101-MW>
USB type <RCM-101-USB>
NOTE:
 A 24V DC power supply is required as the source for the controller and PIO.
 Turn off the power to the controller before inserting or removing the connector for connection
between the teaching pendant and controller.
Inserting or removing the connector while the power is turned ON causes a controller failure.
Power Supply and Emergency Stop Circuit
The following is a circuit example where the emergency stop switch on the teaching pendant is
incorporated into the emergency stop circuit constructed by the customer:
● Internal drive-power cutoff relay type : ACON-C, PCON-C/CF

*1 To cut off the motor drive power supply in conformance with safety category 2, connect 24V to the
EMG terminal and a contactor or other contact device to the MPI/MPO terminals.
*2 When the teaching pendant is connected to the controller, the controller automatically recognizes it.
*3 For the CR contact, the rated voltage and rated current are "24VDC" and "0.1A".
