X1-X8: Encoder Input (1 to 8)
The main encoder input channels for the Brick Motion Controller support only differential quadrature
feedback. 5V supply to power the encoder is provided.
•
4-axis drives with no Option 01 or Option 02 have only X1 to X4, for a total of four encoders
•
Option 01 adds two extra S. encoders: X5 and X6, for a total of six encoders
•
Option 02 adds two more S. encoders on top of Option 01: X7 and X8 for a total of eight encoder
feedbacks.
•
6-axis drives with no Option 02 have only X1 to X6, for a total of six encoders
Option 02 adds two extra S. encoders: X7 and X8 for a total of eight encoder feedbacks.
•
8-axis drives have a default of eight encoders (X1 to X8) and there are no additional encoder options.

Because the same pinouts are used for all encoders, n stands for encoder number 1 to 8: n=1 / axis 1, n=2 / axis 2, etc.
For spacing specifications between the DB- connectors, see Appendix A of this manual.
