Linear Encoder

Encoders should be installed according to the encoder manufacturer's instructions. Care should be taken with the
sensitive electronics of the encoder near the strong magnetic field of the shaft. Particular care should be taken
with magnetic encoders as close proximity to the shaft could cause inaccuracies or damage. Installing the
encoder at a minimum distance of 150mm from the shaft is recommended.
The positive and negative directions of the linear encoder need to be correctly aligned to the direction of motor
movement. The direction corresponding to positive movement can be adjusted in multiple ways:
1. Software configuration on the servo drive.
2. Mechanical orientation of the encoder.
