30 September 2021
The RJ45 socket of the ATV31/312/320 can be used for connection to the following networks and accessories:
a PLC via a Modbus bus or via a CANopen network
a PC/laptop loaded with SoMove software
The VW3A31101 remote display terminal on the ATV31 drive , and the VW3A1006 or VW3A1007 remote display options for the ATV312 and 320 drives.
The Pin out of the RJ45 socket on these drives are as folllows
1 CAN high CAN-H - Signal for CANopen communication
Pin no. Designation Comments
2 CAN low CAN-L - Signal for CANopen communication
3 CAN GND CAN-GND - Signal for CANopen communication
4 D_B Signal for MODBUS communication
5 D_A Signal for MODBUS communication
6 NC Not used
7 10 Volts 0-10 V voltage supplied by the ATV31/312 which can be used to supply the
8 0 Volts converter when connected using PowerSuite software
For Modbus communication, the signals used for the ATV31 /312 / 320 are D-B and D-A only - the other connections are not used.
