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 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 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
Multi-motor switchover 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.
