Connect L7P Servo over RS-485 with Modbus RTU

The XEM CPU can use the built-in RS-485 port to control an LS Electric L7P servo drive. The L7P’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 L7P.

This topic will show the setup of an XEM CPU with one L7P servo drive.
