Modbus Communications

The drive’s serial communication protocol is Modbus RTU slave with a 32 bit data extension.

The Modbus protocol is available on most operator interface panels and PLC’s.

Control Techniques’ Motion Interface panels are supplied with a Modbus master

communications driver.

Multi-Drop Communications

The RS-485 option (pins 4 and 9) is provided for multi-drop configurations of up to 32 drives.

Control Techniques provides a special multi-drop serial cable which allows you to easily

connect two or more drives.
