Which Driver Series Should I Choose If I Need to Read Motor Operating Parameters?

If you need to read motor operating parameters, we recommend using RS series drivers instead of T series drivers.

The reasons are as follows:

  1. T series drivers do not support reading data. This applies to both open-loop T series drivers (DM*****T) and closed-loop T series drivers (CL****T).

Although some T series drivers feature an RS232 interface and support software-based configuration, this interface is intended for motor configuration only and does not support real-time data monitoring.

  1. RS series drivers support reading data, including both open-loop RS series drivers (DM*****RS) and closed-loop RS series drivers (CL****RS).

RS series drivers are equipped with an RS485 interface and support the Modbus RTU protocol over RS485. They feature a built-in 16-segment position display that can be read using our software, allowing you to monitor the motor's operating parameters such as position, speed, and status.

Therefore, if you need to read the motor's operating parameters, we recommend RS series drivers.
