SinCos encoders can be used to evaluate high-resolution encoders. A track signal period is interpolated at a 14-bit resolution (fine interpolation).

Parameters
P. no. | Settings | Function |
---|---|---|
P 0505 | ENC_CH1_Sel | Configuration of the incremental interface |
(0) | OFF | No evaluation |
(1) | SinCos | High-resolution SinCos encoder ( 1 Vss) with fine interpolation |
(3) | TTL | TTL encoder with zero pulse |
P 0540 | ENC_CH1_Abs | Determining protocol type: When starting the device and after changing the encoder parameters, the absolute position of an incremental measuring system is read out via a digital interface. |
(0) | OFF | No evaluation |
(1) | SSI | Serial communication to Heidenhain SSI protocol |
(2) | EnDat | To Heidenhain EnDat protocol (1) |
(3) | Hiperface | To Stegmann-Hiperface protocol (1) |
(4) | SSI_Cont | SSI (1ms clock) |
P 0542 |
ENC_CH1_lines |
Setting of incremental pulses per revolution (value range 1 - 65536) |
P 0543 | ENC_CH1_Multi | Number of multi-turn bits |
P 0544 | ENC_CH1_Single | Number of single-turn bits |
P 0545 | ENC_CH1_Code | Selection of coding: Gray/binary |
P 0551 | ENC_CH1_EncObsMin | Amplitude monitoring |
P 0555 | ENC_CH1_Info | Encoder name |
P 0556 | ENC_CH1_EncObsAct | Amplitude of analog signal |
1) With EnDat and Hiperface the information on single-turn and multi-turn, coding and pulses per revolution is read automatically from the encoder (device must detect encoder product ID). |
