Modbus RTU

The drives with RS485 communication interface conform to Modbus RTU application layer protocol for drives and motion control, which functionality is configured using various commands and variables. The ELD2-RS model also has a termination resistor switch located on the top of the drive. Setting the switch to the correct position, the baud rate can be set to one of the following values: 9600 bps (default), 19200 bps, 38400 bps, 57600 bps. But if using other RS485 drive models such as EM2RS, CS2RS, EL6-RS and EL7-RS, a 120Ω termination resistor is required at the beginning and ending of the chain.
