Can not find documentation
The RJ45 connector uses two wire RS-485 connection for Modbus communications.
Pin 4 is the DB (+). Pin 5 is DA (-). These terminals are for communication.
Pin 7 is 10 VDC and 8 is 0 VDC. These are used to power the remote keypad when connected to this drive or the RS232 to RS485 adaptor when connecting from a PC with Powersuite.
The pins are numbered from Right to Left when looking at the front of the drive.
