Description
Genuine OSA18-A50 servo motor encoder — a rotary absolute position-feedback unit for AC servo motors, available new and tested used/refurbished, 100% tested before dispatch.
The encoder mounts to the rear of the servo motor and provides position and speed feedback to the drive. A faulty encoder is one of the most common causes of servo alarms and erratic axis behaviour — replacing it restores accurate motion control without changing the whole motor.
Configured to your motor
This OSA18-A50 encoder can be programmed with your motor ID to work with the various Mitsubishi servo motors used in Haas machines. Send us your servo motor model / ID and we will supply the encoder ready to fit.
