4.3.4.1 Connection and display

The connector layout, usage, and connecting devices used by the RDM are as follows:

Connector	Usage	External connecting device
CNPM3	Connection of 48 V DC power line (for the motor)	Power precharge module (PPM) CNPM3
CNRDM	Connection of state information signals	Safety control module (SCM) CNPMD

The details of the state display of the RDM are as follows:

LED	Usage	Display details (lamp state)
LED7	Detection of overheating of the regenerative discharge resistor or overcurrent of the discharge current	Overheating of the regenerative discharge resistor (95°C) or Overcurrent of the discharge current (15 A)
LED8	Detection of disconnection of the regenerative discharge resistor	The regenerative discharge resistor is disconnected (displayed even during the regenerative discharge operation)
LED9	Detection of the regenerative discharge operation	Under regenerative discharge operation
LED10	Detection of regenerative discharge overtime	Occurrence of regenerative discharge operation for 10 ms or longer
