Standard functions

Onboard multiple preset speeds

It implements up to 16 speeds via the simple PLC function or combination of X terminal states

Onboard PID

It realizes process-controlled closed loop control system easily.

Auto voltage regulation (AVR)

It can keep constant output voltage automatically when the mains voltage changes.

Overvoltage/ Overcurrent stall control

The current and voltage are limited automatically during the running process so as to avoid frequent tripping due to overvoltage/over current.

Torque limit and control

It can limit the torque automatically and prevent frequent over current tripping during the running process.

Instantaneous stop doesn’t stop

The load feedback energy compensates the voltage reduction so that the AC drive can continue to run for a short time.

Rapid current limit

It helps to avoid frequent over current faults of the AC drive.

High performance

Control of asynchronous motor is implemented through the high-performance current vector control technology.

Timing control

Time range: 0.0–6500.0 minutes

Communication methods

RS485　

Running command channel　

Given by the panel, control terminals,

Serial communication port,can be switched by many ways

Frequency source

10 kinds of frequency source,given by

Digital analog voltage, analog current,Pulse, serial port.can be switched by many ways

Auxiliary frequency source

10 kinds of Frequency source,can easily realize Micro adjustment,frequency Synthesizer

Input and output　

Input terminals

6 digital input terminals, one of which supports up to 100 kHz high-speed pulse input (optional).

2 analog input terminal, one of which only supports 0–10 V voltage input and the other supports 0–10 V voltage input or 4–20 mA current input.

Output terminal

1 digital output terminal 1 relay output terminal

1 analog output terminal :that supports 0–20 mA current output or 0–10 V voltage output

Operation on the operation panel

LED display

It displays the parameters.

Key locking and function selection

It can lock the keys partially or completely and define the function range of some keys so as to prevent mis-function.

　Protection mode

Motor short-circuit detection at power-on, output phase loss protection, over-current protection, over-voltage protection, under voltage protection, overheat protection and overload protection.
