7. Attachment Method of Linear Encoder with distance-coded reference marks
When the position relationship of linear motor moving slider, magnet plate and linear
motor magnetic pole sensor are the conditions indicated by the attachment method in
Linear Motor Descriptions(B-65222EN), the linear scale with distance-coded reference
marks is attached on the machine as following conditions.
In addition, you must check the plus direction of the linear motor and the linear encoder
are in agreement before you attach the linear encoder.

At HEIDENHAIN LS486C.
N in above diagram depends on the designation of the linear motor magnetic pole sensor.
