It realizes up to 16 speeds via the simple PLC function or combination of DI terminal states

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

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

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.

Instant power off not stop

Rapid current limit

To avoid frequently over current faults of the frequency inverter.

Timing control

Time range: 0.0~6500.0 minutes

Multiple communication protocols

Currently supports communication bus via Modbus-RTU and later will support PROFIBUS-DP, CANopen, etc.

Multiple encoder types

It supports incremental encoder and

encoders such as differential encoder, open-collector encoder, resolver, UVW encoder, and SIN/ COS encoder.

Frequency giving

There are 10 kinds frequencygiving: digital setting, analog voltage setting, analog current setting, pulse setting, serial communication port setting, panel potentiometer, etc.

You can switch between these giving in various ways.
