Onboard multiple preset speeds

It implements up to 16 speeds via the simple PLC function or combination of DI terminal states.

Onboard PID

It realizes process-controlled closed loop control system easily.

Auto voltage regulation (AVR)

It can keep constant output voltage automatically when the mains voltage changes.

Overvoltage/ Overcurrent stall control

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

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 CLVC mode.

Individualized functions

High performance

Control of asynchronous motor and synchronous motor are implemented through the high-performance current vector control technology.

Power dip ride through

The load feedback energy compensates the voltage reduction so that the AC drive can continue to run for a short time.

Rapid current limit

It helps to avoid frequent overcurrent faults of the AC drive.

Virtual I/Os

Five groups of virtual DI/Dos can realize simple logic control.

Timing control

Time range: 0.0-6500.0 minutes

Individualized functions

Multi-motor switchover

Four motors can be switched over via four groups of motor parameters.

Multiple communication protocols

It supports communication via Modbus-RTU, PROFIBUS-DP, CANlink and CANopen.

Motor overheat protection

The optional I/O extension card enables AI3 to receive the motor temperature sensor input (PT100, PT1000) so as to realize motor overheat protection.

Multiple encoder types

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