It supports 3 types communication via RS-485, Profibus-DP, CAN.

Motor overheatprotection

The optional I/O extension card enables AI3 to receive the motor temperature sensor input.

Multiple encoder types

It supports various encoders such as differential encoder, open-collector encoder, resolver and UVW encoder.

Overvoltage / Over current stall control

The current and voltage are limited automatically during the running process so as to avoid frequent tripping due to overvoltage/overcurrent.

Rapid current limit

It helps to avoid frequent over current faults of the AC drive.

Torque limit and control

It can limit the torque automatically and prevent frequent over current tripping during the running process. Torque control can be implemented in the FVC mode.
