Type
Function

Frequency Source

14 main sources, 14 auxiliary sources.
Easy switch between different modes.
Diversified input modes for every source: keyboard potentiometer, external analog,
digital setting, pulse frequency, multi-speed, simple PLC, communication, computing
results, etc.

Torque Source

14 torque sources, including digital setting, external analog, pulse setting,
multi-order, communication, computing results, etc.

Acceleration and 

Deceleration Time

4 groups of lines (can be switched through the option terminals); S Curve 1, S Curve 2

Emergency Stop

Interrupt the output instantaneously

Multi-speed

16-shift speeds at most; can be switched by different combination of order terminals

Simple PLC

Continuous operation of 16-shift speeds; the acceleration/deceleration time, operating
time and frequency source for every shift can be set separately

Inching Control

Inching frequency and inching acceleration/deceleration time can be set separately;
Inching can be prioritized in process.

Rotating-speed Track

Track the start speed and operating speed of the inverter’s load

Length and Distance Control

Length and distance control through pulse inputs

Counting

Counting through pulse inputs

Swing Frequency

For winding machines in the textile industry

Internal PID

Closed-loop process control system is available

AVR

Ensure constant output in case of fluctuating grid voltage

DC Brake

Quick and stable parking is available

Slip Compensation

Compensate the slip deviation due to increased load

Hopping Frequency

Prevent resonance with the load

Droop Function

Balance the load rate of different motors which drive the same load

Timing

Automatic stop at a given time
