FRENIC-Lift (LM1S)
Product information

Optimum Exclusive Design for Passenger Elevators

A braking circuit is built in the AC Drives of all the capacities.
Built-in PG feedback circuit is standard equipment.
An optional keypad is available.

Higher Performance

Overload capacity: 200% for 10s*1)
Current response (ACR):500Hz
Reduction of torque ripple realizes low vibration.
Reduced roll-back during starting up.

*1: Except for 200 V / 22 kW and 400 V / 30 kW

High performance vector control

Current response (ACR): 500Hz
Speed control accuracy: ±0.01%

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).

Model variations

FRENIC-Lift AC Drives are available in a series with capacities ranging from 4.0 to 45kW for three-phase 400V model.
5.5 to 22kW for three-phase 200V model.
2.2kW for single-phase 200V model.

Applicable to the feedbacks from various pulse generators

Applicable to the inputs by open collector/complementary output as a standard specification (Encoder power supply is switchable between +12V and +15V.)
Applicable to the inputs from the 5V line driver as an option
Applicable to Sin/Cos, Serial interface (EnDat2.1) and Parallel interface (4-bit gray code, UVM 3-bit code)
