2.1.3 Reference Point of Dis series Motor and Encoder
- 57 -
Reference point of Dis series motor
Reference point of Dis series motor is as follows.
Reference points of motor are on every magnetic pole unit. For
example, in case of 40 poles motor, the reference points are on every
18 degrees (360/(40/2)) based on the figure above.
Reference point of rotary encoder (HEIDENHAIN RCN223)
Reference point of HEIDENHAIN RCN223 is as follows.
Reference point is where the small white refarence marks meet
viewing from the feedback cable side.
NOTE
Be sure to confirm the correct reference point of
encoders. For an incremental encoder, it has also a
reference point in itself. For details, contact a
manufacturer of encoder.
