Rescue operations

During rescue operations, the AC Drive is operated (for braking) with a single-phase 200 V or battery-powered power supply to enable movement to a door area.

(Note 1)

Only when using serial encoder (EnDat2.1, Biss-C)

(Note 2)

Requires input of the voltage specified for the control power supply auxiliary input.

(Note)

During rescue operations, braking operations are implemented.
For details, refer to the User’s Manual.

Supports various motor combinations.
Contributes to improvedelevator ride quality by improving encoder detection accuracy.

Improves AC Drive control performance

The current response (ACR) of the AC Drive is 500 Hz. Improves detection accuracy at very low speeds with a sine-wave encoder.

Improves AC Drive control performance

Reduces rollback

Reduces rollback via improved performance. Improves ride comfort.

Improves encoder detection accuracy

Improved encoder detection accuracy enhances imbalance load compensation performance.
Capable of simplifying load cells.

(Note)

Only when incremental signal uses a sine wave encoder

Customizable logic functions

The FRENIC-Lift (LM3) Series also features the customized logic functions of the FRENIC-Ace (E3)/MEGA (G2) Series.

Built-in simple PLC functions that enable programming for the AC Drive. FRENIC-Lift (LM3)

PC loader
Flexible development environment

Enables intuitive programming with PC loader support. Function blocks (FBs) created by users can be exported/imported and shared with other users. FBs can also be given a control number and can be password locked to conceal their internal logic.

Flexible development environment

Supports various combinations

Supports various encoders and motors combinations.
Standardly supports sine wave encoder (1Vpp) and serial encoder (EnDat2.1, Biss-C).

“Edit”, “Read”, “Transfer”, “Compare”, “Initialize”, and “Store data” for function codes.

Trace
Trace

Confirm with waveform
Displays a trace of the present status of current, voltage, and digital terminals as analog and digital waveforms. Capable of saving and loading trace data.

Monitor
Monitor

What is the present status?
Displays meter values of operating conditions in real time. Capable of displaying trip history, I/O status, and serviceable parts status.

Preventive maintenance and predictive maintenance

The keypad and PC loader make it easy to check the status of equipment and detect problems before they occur, helping to reduce production equipment maintenance time and downtime.

Preventive maintenance and predictive maintenance

Long life expectancy (main components)

Many of the serviceable parts inside the AC Drive have been designed to meet customer equipment maintenance cycles.
