The lift control unit handles communication with landing buttons, controls the cabin electronics, communication to the centre via GPRS or Ethernet (Kk Webrman application).

The unit

  • collects requests from landing buttons and cabin panel, processes them according to set, requirements and transfers instructions to the drive control unitBC-NELA-LCS.jpg
  • receives instructions for changing parameters from the centre
  • transfers diagnostic and operating data to the centre

In the variant without a machine room, the lift control unit is located in the door frame.

Lift drive control converter

The Frenic Lift and Zetadyn 4 frequency converters used are designed for the control of

  • gear machine with asynchronous drive
    • with pseudovector control (without encoder)
    • with direct vector control (with encoder)
  • gearless machine with synchronous drive.

In the variant without a machine room, the drive control converter is located in the lift shaft.

Frenic Lift

An extremely robust converter with a high overload capacity developed especially for lift technologies.

Zetadyn 4

A converter designed for installation into the switchboard or on the wall in the machine room or lift shaft. It allows operation of the lift drive without contactors.
