6) Decrease the DG gain by increments of 0x1.
The length and phase variation should be re-checked after any
of the six possible adjustments above.
Once the total phase variation is reduced as much as possible, the final
adjustment if desired, is the Phase Correction Dead Band ( PH0 serial
command ) . See Follower Cycles
Once this is accomplished, Phase Correction Limit , does not need to
change unless there are large Follower Length or sensor position
changes due to a machine or product change.
Note: The value of FM7 plus FM8 is tested against the Phase Distance
Error Limit (+) and Phase Distance Error Limit (-) to activate the
In Phase output. An alternate way of minimizing phase
variation is to monitor the
In Phase , output function 24 and
adjust Phase Correction Limit slowly while reducing the Phase
Distance Error Limit(+) and Phase Distance Error Limit(-) to the
performance desired. This is a better approach for high speed
applications because of the inherent latency of serial
commands.
