JOB SIZES P1/1
Sync Mode
Sync Mode (CP-203) selects the algorithm to be used when RUN Mode (CP-202) is set for Follower or Inverse Follower.
0 = Non-Sync Mode the position follower only, sync pulses are ignored by the control algorithm. 1 = Fixed Mode the
follower setpoint is the ratio/scale factor. 2 = Trend Mode the follower setpoint is altered by the control algorithm to
allow for continuously changing job sizes. 3 = Learn Mode learns the job spaces and the scale factor, also modifies the
follower setpoint.
3 = Learn
2 = Trend
1 = Fixed (default)
0 = Off
LdSyncDvd
Lead Sync Divide (CP-205) can be used to reduce the sync rate of the CX-1200 for those processes that may need the
maximum sync rate of 20 pulses per second. The lead sync pulses are divided by the LdSyncDvd (CP-205) value before
being submitted to the synchronization routine.
FbSyncDvd
Feedback Sync Divide (CP-206) can be used to reduce the sync rate of the CX-1200 for those processes that may need
the maximum sync rate of 20 pulses per second. The follower sync pulses are divided by the FbSyncDvd (CP-206)
value before being submitted to the synchronization routine.
LdSyncBand
Lead Sync Band (CP-335) sets a “dead-band” around the sync-mark position to allow for irregular sync marks. If the
actual sync pulse occurs inside this “dead-band”, the CX-1200 will presume an “in-sync” status, and therefore make no
sync-correction. A sync correction will be made if the sync pulse occurs outside this band. The band is defined as ±
the value entered.
FbSyncBand
Feedback Sync Band (CP-336) sets a “dead-band” around the sync-mark position to allow for irregular sync marks. If
the actual sync pulse occurs inside this “dead-band”, the CX-1200 will presume an “in-sync” status, and therefore
make no sync-correction. A sync correction will be made if the sync pulse occurs outside this band. The band is
defined as ± the value entered.
LdJbSzAct
Lead Job Size Active (MP-14) displays a running average value of the last 16 qualifying lead job sizes determined by the
Lead Frequency and Lead Sync inputs. Displayed in EU’s. This is the job size currently being used by the control
algorithm.
FbJbSzAct
Follower Job Size Active (MP-24) displays a running average value of the last 16 qualifying follower job sizes deter-
mined by the Follower Frequency and Follower Sync inputs. Displayed in EU’s. This is the job size currently being
used by the control algorithm.
ScaleFactor
Scale Factor (MP-41) displays the calculated ratio between the LdJbSzAve (MP-13) and the FbJbSzAve (MP-23). This
may be different than the scale factor actually being used by the control algorithm.
