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.

Item		specification
Individualized functions	High performance	Control of asynchronous motor is implemented through the
	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 IO	Five sets of virtual input and output for simple logic control
	Timing control	Time range: 0.0~6500.0 minutes
	Multi-motor switching	Four sets of motor parameters for four motor switching control
	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
	Multiple encoder types	It supports incremental encoder and encoders such as differential encoder, open-collector encoder, resolver, UVW encoder, and SIN/ COS encoder.
