Encoder
All response times must be multiplied by the factor 1.002.
Calculation factor (formula symbol) | Calculation specification response time |
---|---|
Sine/cosine encoder: |
|
| T_Sys + T_Task |
| Filter time speed (8708.3) + T_Task + T_Sys |
| Filter time acceleration (8708.2) + 2 × T_Task + T_Sys |
EI7C built-in encoder: |
|
| T_Sys + T_Task |
| 3.5 × 1/n_Actual + T_Task + T_Sys + Filter time speed (8708.4) |
SSI encoder: |
|
| TENC_POS = SSI frame rate × (SSI fault tolerance - SSI encoder (8713.51) + 1) + 9 × T_Task |
| TENC_VEL = SSI frame rate × (SSI fault tolerance + 2) + filter time speed (8708.3) + 9 × T_Task |
| TENC_ACC = SSI frame rate × (SSI fault tolerance + 3) + filter time acceleration (8708.2) + 9 × T_Task |
| TENC_VEL = SSI frame rate × [round up (SSI refresh time + jitter / SSI frame rate) -1] + SSI frame rate × round up (filter time speed (8708.3) + SSI refresh time + jitter) / SSI frame rate + SSI frame rate × (SSI fault tolerance +1) + filter time speed (8708.3) + 9 × TTask |
| TENC_ACC = SSI frame rate × [round up (SSI refresh time + jitter / SSI frame rate) -1] + 2 × SSI frame rate × round up [(0.5 × filter time acceleration (8708.2) + SSI refresh time + jitter) / SSI frame rate) + SSI frame rate × (SSI fault tolerance +1) + filter time acceleration (8708.2) + 9 × TTask |
