Page 37: Index Speed Considerations
Each time an MII6800, MII6700, or MII6500 encoder is powered up, the first pass over the index mark must occur at a speed ≤1 m/s. Once the index is initially detected, the index will function at all speeds (up to 10 m/s) until the next power cycle. IM-1004 | REV181127 Page 35 ©2018 Celera Motion... -
