Index Speed Considerations
for M II 6000
C5.0 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.
