Control method

PWM modulated sinusoidal phase

Brakes

Starts at a lower frequency than deceleration via the STOP instruction, at a lower set value during operation, or via an external input

Input

Multi-function digital input

Way out

Multi-function output, frequency display, relay output

Protection function

Overcurrent, overvoltage, undervoltage, thermal electronics, temperature fault, ground overcurrent-fault in Poweron state, limit overload, overvoltage incoming, outgoing out, memory error, CPU error, USP trip, communication fault, overvoltage protection during deceleration, momentary power-off protection, emergency shutdown

Main function

Auto detect engine speed when power off using speed sensor
KEB function keeps the engine running stably when power is lost using regenerative energy
Capable of sensorless control (IPM motor position control without feedback from the motor (encorder) and without additional controller).
Provides many features to make setting up and operating the inverter easy such as: auto-tuning mode...
Built-in PID controller

The media

RS-485

Expansion device

LCD operation screen, AC reactor, DC reactor, brake unit, brake resistor, noise filter...
Speed reference card, communication card, monitoring card, transmitter speed control card

Protection level
