A Modbus communication error in YASKAWA Industrial Electrical can stem from several issues. Check for incorrect wiring, short circuits, or disconnected cables. Electrical interference can also cause data errors, so inspect the control, main circuit, and ground wiring. Ensure the communication protocol is compatible by examining the values set in H5-xx. If H5-09 [CE Detection Time] is too small, adjust the controller software settings. Finally, investigate the controller for any software or hardware problems.
