They can control both synchronous as well as induction motors. Low Voltage Converters go. This means that from the inherent principle, 4-quadrant operation is possible without requiring any additional measures.

Turn on more accessible mode. Two closed-loop control types for induction motors: Depending on the particular requirement, they can be flexibly used for supply voltages extending from V to V. Comfortable operation possible — even without speed feedback for asynchronous motors, up to approx.

Mechanical degree of protection: ATEX-certified for motors located in hazardous zones with Accessory kit S, also with very long motor cable length. IP21, higher degrees of protection optionally available. IP21, higher degrees of protection optionally available To the top of the page. Speed feedback for synchronous motors: 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 Turn off more accessible mode.

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.

Today, elevator drives are designed either as gearless or as geared solutions. Safe, reliable and disturbance-free operation using the integrated filter, reactors and contactor s for the travel commands.
