X521 / X531: Encoder connection 2 for HTL/TTL/SSI encoder with open-circuit monitoring
Table 4- 61 Encoder connection X521
Connector Terminal Signal name Technical data
1 A Incremental signal A
2 A* Inverse incremental signal A
3 B Incremental signal B
4 B* Inverse incremental signal B
5 R Reference signal R
6 R* Inverse reference signal R
7 CTRL Control signal
8 M Ground via inductivity

Note
Operation of unipolar HTL encoders
When unipolar HTL encoders are deployed, A*, B*, and R* must be jumpered on the terminal
block with M encoder (X531).
