Index Speed Considerations

MII6000

Maximum Speed for MII6000 Index after Power-up (MII6800, MII6700 and MII6500 Models):

Each time an MII6800, MII6700, or MII6500 encoder is powered up, the first pass over the index
mark must occur at a speed

≤1m/s. Once the index is initially detected, the index will function at

all speeds (up to 10m/s) until the next power cycle.
