l None-Stop when instantaneous power off.

l Speed Trace Function: Smoothly start the running motor.

l Automatic Voltage Regulation Functin (AVR):

l Up to 23 fault protections over current, over voltage, under voltage, over temperature, phase failure, overload etc.

Man-machine Interface

LED Display

Can display setting frequency, output frequency, output voltage, output current etc.

Multi-function Key-press

The QUICK/JOG key-press can be used as multi-function key-press.

Environmental Constraint


-10°C~+40°C.Inverter will be derated if ambient temperature exceeds 40°C.


≤90%, without condensation


≤1000M, output rated power

>1000M, output power with derating

Impingement and Osciliation

The inverter is prohibited to drop on the floor or with suddenly impact, it also prohibited to be installed at the place where the osciliation may occur very probably.

Electromagnetic Radiation

The inverter is prohibited to be installed at the price where stronger electromagnetic radiation may occur very probably.

Store Environment

The inverter is prohibited to be stored at the place where with direct sunlight, fall of oil mist, steam and with heavy osciliation..
