The 20-COMM-E module supports various communication protocols, such as EtherNet/IP, DeviceNet, ControlNet, and PROFIBUS, depending on the specific model. It enables bidirectional data transfer between the drive and the control system, allowing for monitoring, control, and diagnostics of the drive parameters.

This communication module offers features like parameter configuration, drive starting/stopping, speed and torque control, alarm monitoring, and fault diagnostics. It also provides status and diagnostic information to the control system, enabling real-time monitoring of the drive's performance.
