Product Overview

The Yaskawa CIMR-LB4A0045FAA is a 22 kW L1000A elevator drive with a rated output current of 45 A. Designed for three-phase 380-480 VAC systems, it provides dedicated control functions for medium-to-higher-power elevator traction motors. The drive supports both induction and permanent-magnet synchronous motors and can be configured for encoder-feedback vector control using a compatible PG option card.

Main Features

• Dedicated elevator software for traction-drive control and system integration.
• Supports geared induction and gearless permanent-magnet motor systems.
• Closed-loop vector control provides accurate low-speed torque and speed regulation.
• Motor autotuning functions support motor and drive matching.
• Brake-sequence control assists controlled torque buildup and brake release.
• Ride-comfort functions reduce torque ripple and speed-transition vibration.
• Rescue-operation support for properly engineered emergency power systems.
• Dual-channel Safe Disable supports Safe Torque Off up to SIL2 and PL d.

Technical Specifications

Compatible System and Applications

The CIMR-LB4A0045FAA can be used in compatible elevator traction systems requiring up to 45 A rated drive output. It is suitable for modernization and replacement projects where the original motor, encoder, control logic and braking system have been technically verified.

Maintenance and Replacement Notes

Check the full model suffix, motor current, encoder and PG card, control power, safety-monitor logic, mechanical brake sequence and regenerative-braking configuration. This capacity may use a braking arrangement different from lower-powered L1000A models. Do not reuse a braking resistor or braking unit without checking its voltage, resistance, current and duty-cycle rating.
