Connect L7C Servo over RS-485 with Modbus RTU

The XEM CPU can use the built-in RS-485 port to control an LS Electric L7C servo drive. The L7C’s RS-422 port can talk to the XEM CPU’s RS-485 port when wired as shown in this example. Index positioning can be done over Modbus RTU between the XEM CPU and the L7C.

This topic will cover the setup of an XEM CPU with one L7C servo drive.
