Input terminal

The 4-way Digital Input Terminal (DI1-DI4) can be additionally expanded by 2-way (DI5-DI6) through connecting with the IO expansion card, DI6 can be connected with the high speed impulse input 1-way analog input terminal (VF1) which can be additionally expanded by 1-way (VF2) through connecting with the IO expansion card, and it can be also used as digital input terminal via setting.  

Operating instruction: VF1 can serve as the voltage (0V-10V) or current (0/4mA~20mA) input, however, VF2 can only serve as voltage (0V~10V) input.

Output terminal

The 1-way Analog Output Terminal FM1 can be additionally expanded by 1-way (FM2) through connecting with the IO expansion card, both the voltage (0V-10V) and current (0mA~20mA) can be output, the 1-way relay outputs T1, below 30V/1Afor DC and below 250V/3Afor AC.

Operation

Mode of operation

Keyboard, terminal, RS485 communication  

Frequency source

14 main frequency sources, 14 auxiliary frequency sources. They can be combined and switched via multiple modes. The input mode of each frequency source can adopt multiple ways: keyboard potentiometer, external analog, digital reference, impulse reference, Multiplex Directive, simple PLC, communication, arithmetic results, etc.

Torque source

14 kinds of Torque Sources, including digital reference, external analog, impulse reference, Multiplex Directive, communication, arithmetic results, etc.

Acceleration and Deceleration Time

4-group straight line (terminal switch can be selected via acceleration and deceleration time), S curve 1 and S curve 2.

Emergency stop

Interrupt frequency inverter output instantly

Multiplex Speed

16-phase speed is allowable to set at most and use various combination of multiplex directive terminal to switch

Simple PLC function

Continuously run 16-phase speed and independently set acceleration and deceleration time and running time

Jogging Control

Independently set Jogging frequency and jogging acceleration and deceleration time, additionally, set the unit under running state and confirm whether the jogging is preferential

Rotating Speed Tracking

Frequency inverter starts operation by tracking the load speed

Fixed-length and fixed-distance control

Realize fixed-length and fixed-distance control function through Impulse Input
