2.2 Basic description

Inverter

The specific crane features for the inverter hardware and the special software are achieved by combining the

experience and know-how of crane applications with the latest technology.

Crane user interface

Interface with pre-designed locations for typical crane functions. The main part of this interface is carried out

by a terminal strip, which has separated sections for signals with main, control and electronics voltage levels.

Brake control

Includes the brake contactor for disk brakes.

Electrical Braking

Includes a braking transistor and a braking resistor.

Control modes

Can be controlled by

the electronic potentiometer control with 2-step or 3-step pushbuttons,

the multistep control with 2-5-step controllers.

the automation control using any control device with an 0-10V output (computer, radio, PLC)

Limit switch functions

Built-in slowdown (S11, S21) or stop limit switch (S12, S22) functions for both running directions.

Protections

Includes a motor thermal protection, which is based on motor temperature measurement by Klixon placed in

motor windings. A great number of other protections included are shown in the technical data.
