FRENIC-Lift series inverter is specially designed for operation of induction and permanent magnet
synchronous motors used in lift applications. Also induction motors without encoder (open loop) can be
controlled obtaining good performance and high positioning accuracy at stop.
The main characteristics of FRENIC-Lift are:
- Compact dimensions with high output power.
- Rescue operation with Battery or UPS with indication of recommended direction.
- Short floor operation with two different modes.
- 200% overload for 10 seconds.
- Communication protocols DCP 3 or CANopen integrated.
- Modbus RTU Protocol is integrated as standard.
- Incremental encoder input (12 V or 15 V / Open Collector).
- Optional cards for different encoder types (Line Driver, EnDat 2.1, SinCos...).
- Pole tuning and Auto tuning without removing the ropes (load).
- Multifunctional, detachable keypad.
- Braking transistor is integrated in all capacities.
- Operation of Induction motor without encoder (open loop) is possible.

High overload capacity
200% of rated current for 10s*2)
(Overload begins from 80% continuous operation with a carrier frequency of 10kHz.)
*2) Except for 200 V / 22 kW and 400 V / 30 kW
IM/PMSM common drive
A single AC Drive can control an induction motor (open/closed loop control) and a synchronous motor (the optional PG interface card is required).
