Yaskawa CIMR-LB4A0018FAA L1000A Elevator Drive 400V 7.5kW 18A
Product Overview
The Yaskawa CIMR-LB4A0018FAA is a 7.5 kW L1000A elevator drive designed for three-phase 380-480 VAC traction systems. With an 18 A rated output, it provides specialized control for elevator induction motors and permanent-magnet synchronous motors. The drive is suitable for installed-base maintenance, modernization and technically verified replacement of the same L1000A configuration.
Main Features
- Dedicated control functions for elevator starting, acceleration and direct stopping.
- Supports geared induction motors and compatible gearless PM motors.
- Open-loop current vector and closed-loop vector control capability.
- Compatible encoder-feedback options for precise speed and position-related control.
- Automatic motor tuning helps match the drive to the traction motor.
- Brake-control sequencing assists smooth torque buildup before brake release.
- Torque-ripple suppression reduces motor vibration and improves ride comfort.
- Safe Disable inputs provide Safe Torque Off functionality up to SIL2 and PL d.

Compatible System and Applications
The CIMR-LB4A0018FAA is suitable for compatible passenger lifts, goods lifts and elevator-modernization systems using an appropriately rated traction motor. Elevator load capacity, rated speed and travel height depend on the complete mechanical and electrical system and should not be inferred from the 7.5 kW drive rating alone.
Maintenance and Replacement Notes
Confirm the complete suffix, not only CIMR-LB4A0018. Check the original encoder type, PG card, motor rated current, brake timing, braking resistor, safety-chain wiring and controller interface. Parameters from another L1000A capacity should not be copied without engineering review. Validate the Safe Disable circuit and mechanical brake operation after replacement.
