The power flows from the line supply to the motor for a motoring load. Two closed-loop control types for induction motors: Motor cable length shielded or non-shielded: Direct forced air cooling, automatic temperature control.

Today, elevator drives are designed either as gearless or as geared solutions. Customer benefits Cabinet units in IP21 or higher degrees of protection All of the drive units have their own connection space Compact dimensions Equipped with radio interference suppression Low harmonics fed back into the line supply, mainly on and pulse versions Almost unlimited motor cable lengths possible inherent to the system High overvoltage strength, e.

Typical applications Elevators for passengers and loads, implemented as cable elevators according to DIN EN Inclined elevators To the top of the page. Depending on the particular requirement, they can be flexibly used for supply voltages extending from V to V.

Safe, reliable and disturbance-free operation using the integrated filter, reactors and contactor s for the travel commands.


Low Voltage Converters go. Medium Voltage Converters go. Speed feedback for induction motors: ATEX-certified for motors located in hazardous zones with Accessory kit S, also with very long motor cable length. Depends on the motor Line supply frequency: IP21, higher degrees of protection optionally available To the top of the page.

Customer benefits Compact and ready-to-connect unit lober integrated EMC filter, line reactor, braking chopper, braking resistor and a quiet contactor for the travel commands. Compact and ready-to-connect unit with integrated EMC filter, line reactor, braking chopper, braking resistor and a quiet contactor for the travel commands. Technical data overview Rated dynavedt voltage Typ. They have a fully controlled B6 bridge circuit on the line side and a B6 inverter circuit on the output side, which utilizes the principle of interphase commutation; this distributes the DC link current from the DC link reactors with a square waveform with frequency f to the motor winding.

Line supply cos phi 1: Speed feedback for synchronous motors: Mechanical degree of protection: Skip directly to content. Tools Drive Technology Drive Technology. IP20 Ambient temperature, storage: Low Voltage Converters go.


This means that from the inherent principle, 4-quadrant operation is possible without requiring any additional measures. Medium Voltage Converters go. Turn off more accessible mode. Up to an elevator power of 30 kW the drive unit can be accommodated in a control cabinet with a depth of mm.

They can control both synchronous as well as induction motors. Their equipping means that they can be easily used in all operating environments — even in hospitals and chemical plants.

Transparent operator control and setting using a menu-prompted 4-line plain text display with membrane keypad at the drive inverter — or up to m away in the main control room via RS Selection and Engineering Tools go. Selection and Engineering Tools go. Possible with lohed motors up to 1. Search Search term s Search.

For regenerative operation, the rectifier on the line-side feeds the regenerated energy back into the line supply.

As a consequence, the motor cable olher is almost unlimited. Turn off more accessible mode.
