Built-in PLC, multiple speeds

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

Built-in PID

It realizes closed loop control system easily.

Auto voltage regulation (AVR)

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

Overvoltage/ Over current stall control

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

Rapid current limit function

It can auto limit running current of frequency inverter to avoid frequently tripping.

Torque limit and control

(Excavator characteristics) It can limit the torque automatically and prevent frequently over current tripping during the running process.

Torque control can be implemented in the VC mode.

Individualized functions

High performance

Control of asynchronous motor is implemented through the high-performance current vector control technology.

Instant power off not stop

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

Rapid current limit

To avoid frequently over current faults of the frequency inverter.

Timing control

Time range: 0.0~6500.0 minutes

Multiple communication protocols

Currently supports communication bus via Modbus-RTU and later will support PROFIBUS-DP, CANopen, etc.

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 incremental encoder and

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

Advanced background software

It supports the operation of frequency inverter parameters and virtualoscillograph function, by which the state of frequency inverter can be monitored.
