Figure 55 - Feedback Group Parameters
Follow these steps to configure the type of feedback used by the safety option.
1. From the Feedback group, choose the P27 [Fbk Mode] parameter.
2. Set the P27 [Fbk Mode] parameter value to 0 (default) for redundant
processing and cross-checking of the single encoder input in a 1oo2
architecture.
3. Choose the P28 [Fbk 1 Type] parameter.
The default value is 1 for incremental encoder input.
4. Set the P28 [Fbk 1 Type] parameter value to 0 for Sine/Cosine and
internal monitoring of the single encoder input.
5. Choose the P29 [Fbk 1 Units] parameter.
6. Set the P29 [Fbk 1 Units] parameter to 0 (default), which equals Rotary
feedback.
7. Choose the P30 [Fbk 1 Polarity] parameter.
8. Set the P30 [Fbk 1 Polarity] parameter to 0 (default) to set up the
direction for monitoring to be the same as the encoder direction
(Normal).
9. Choose the P31 [Fbk 1 Resolution] parameter.
10. Choose 1024 (default) or enter value between 1…65,535 pulses/
revolution based on the encoder’s specifications.
11. Choose the P32 [Fbk 1 Volt Mon] parameter.
