Product Overview

The Yaskawa CIMR-LB4A0024FAA is an 11 kW L1000A elevator drive rated for 24 A output current and three-phase 380-480 VAC input power. It is designed specifically for elevator traction control and provides functions for motor torque regulation, brake sequencing, direct stopping, rescue operation and ride-comfort optimization.

Main Features

• Dedicated L1000A elevator-control platform.
• Supports induction and permanent-magnet synchronous motors.
• Open-loop vector and encoder-feedback closed-loop vector control.
• Motor autotuning for improved motor and drive matching.
• Brake timing functions for controlled holding-brake operation.
• High low-speed torque capability for vertical elevator loads.
• Torque-ripple suppression improves passenger comfort.
• Safe Disable inputs provide Safe Torque Off functionality up to SIL2 and PL d.

Technical Specifications

Compatible System and Applications

This drive is suitable for compatible geared and gearless elevator installations, passenger lifts, freight lifts and modernization systems. The 11 kW rating does not by itself define elevator load capacity or rated travel speed; final selection must be based on traction-machine and controller data.

Maintenance and Replacement Notes

Verify CIMR-LB4A0024FAA against the complete original nameplate. Confirm the motor type, rated current, encoder output, PG feedback card, brake-control signals, safety circuit and braking resistor. Parameters must be reviewed before transfer because motor and elevator settings can vary even between drives with the same power rating.
