Overload capacity

Heay load application: 60s at 150% rated current @40°C. The time depends on the drive temperature under other conditions.
General application: 60s at 120% rated curent @40°C. The time depends on the drive temperature under other conditions.

Torque boost

Automatic torque boost. Manual torque boost 0.1%-30%

Built-in PID

Conveniently achieve the process control close-loop control system

Torque limiting and control

The torque is automatically limited operating (to avoid frequent overcurrent jumping fault due totoo large torque).
