Function

Channel of operation command

Keyboard control,terminal control,communication control

Start mode

Line start, DC injection braking before start, speed tracking before start

DC injection braking

Start DC injection braking, stop DC injection braking

Dynamic braking

Built-in braking unit < = 15kw,get external braking unit>15kw

Frequency source choice

Keyboard digital frequency setting, analogue V1 setting, analogue V2 setting, Keyboard potentiometers setting, Multiple speed operation setting,

PID control setting, telecommunications setting, PLC program setting, HDI Rapid Pulse setting

Main and auxiliary frequency combination set

Just main frequency setting, just auxiliary frequency setting, QUICK/JOG or terminal switching selection, main frequency + auxiliary frequency, main frequency - auxiliary frequency, maximum, minimum, could realize

Frequency overlay and fine adjustment function

Frequency resolution

Keypad setting:0.01Hz; Analog setting: 0.1Hz

Carrier frequency

0.5Khz~15.0Khz, both PWM mode could be chosen

Acc/Dec time

0.1~3600.0s

Multiple VF curve

Linear V/F curve, 2.0 times power drop torque V/F curve, custom V/F percentage (can realize manual energy saving control), multipoint VF curve.

Built-in PID

Built-in PID controller, apply to process control occasion such as water or gas supply. Meanwhile the function of sleep wake up could save energy to the great extent possible.

Simple PLC operation

16 segment goal setting, frequency or mode of percentage setting could be chosen, each segment of operation time and direction could be set separately, and realize timing stop function.
