KE300-01 Series Wall-Mounted Bare Metal Inverter

According to the application characteristics of the supporting electric control cabinet, a special product is developed to enhance environmental tolerance and the protection level. Installed in the electric control cabinet can effectively avoid the secondary pollution of other equipment such as dust, moisture, oil gas, fibre and other foreign objects.

Features

Easy to install and debug

Rugged EMC design

Adopt modular design, configuration is very flexible

The main control system uses 32-bit high-speed DSP, integrated PG-free vector control, V/f control, and torque control.

With swing frequency, fixed length/fixed diameter, crawling positioning and other functions.

Perfect protection functions: over-voltage/under-voltage protection, inverter overheat protection, ground fault protection, short circuit protection, overcurrent protection, overload protection, etc.

fluctuating

Control

Function Common DC bus Common DC bus for several inverters, energy balanced automatically

Torque control Torque control without PG

Torque limit “Rooter” characteristics, limit the torque automatically and prevent

frequent over-current tripping during the running process

Wobble frequency control Multiple triangular-wave frequency control, special for textile

Timing/length/counting control Timing/length/counting control function

Over-voltage & over-current stall control Limit current & voltage automatically during the running process,

prevent frequent over-current & over-voltage tripping

Fault protection function Up to 30 fault protections including over-current, over-voltage,

under-voltage, overheating, default phase, overload, shortcut, etc., can

record the detailed running status during failure & has fault automatic

reset function
