Inverter drives for Lifts
Inverter drives for Lifts

An inverter drive is used to convert an alternating current of a certain frequency into a current with the necessary parameters (frequency from 1 to 800 Hz). This allows you to smoothly control the operation of both synchronous and asynchronous electric motors of various capacities. The use of inverter drive also allows you to convert a single-phase voltage to three-phase.


The compact lift inverter drive L1000V is designed for low speed operation (up to 1 m/sec) of geared motors. Optimised standard functions simplify set-up, operation and maintenance, while ensuring smooth and comfortable rides. It upgrades lift systems in terms of reduced costs and enhanced comfort.

- One motor contactor solution in compliance with EN81-1

- Two relay outputs for fault and brake control reduce installation effort and costs.

- Simple and efficient brake sequences enable smooth operation.

- Five independent settings of S-Curves to prevent jerks

- Pulse input feedback with PG and load detection during run to increase levelling accuracy
