Cyclic encoder evaluation via channel 1 (SinCos X7)
On channel 1 (SinCos, X7) digital encoders can be cyclically read. The selection is made via P 0505 ENC_CH1_Sel. The number of MT/ST bits is set via parameters P 0543 and P 0544.

NOTE: As encoders with different protocol modes exist (with/without error bit, parity bit, etc.), LTi DRiVES GmbH should be consulted before using them. |
