Built-in simple 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 outputvoltage 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 and synchronous motor are 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. 

Virtual I/O

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

Timing control 

Time range: 0.0~6500.0 minutes

Two motors can be switched by two groups of motor parameters. 

Multiple communication
protocols
 

It supports communication bus 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.

Advanced background software 

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