Table-29 Entering Offset Scaling Analog Setpoint Parameters
CP Parameter Name Parameter Value
CP-84 Analog Input Allocation
CP-21 Follower Engineering Units
CP-34 Max RPM Feedback
CP-31 PPR Feedback
CP-33 Max RPM Lead
CP-30 PPR Lead
Setting CP-84 to a value of "3"allocates
the analog input to be used an offset.
The desired Follower Engineering Units
when the lead and feedback are
operating at their maximum speeds; i.e.
Max RPM Lead (CP-33) and Max RPM
Feedback (CP-34).
Enter the maximum operating RPMs
measured at the feedback sensor shaft.
Enter the resolution of the feedback
sensor.
Enter the maximum operating RPMs
measured at the lead sensor shaft.
Enter the resolution of the lead
sensor.
Enter the analog level, as a percent of
the full scale analog level, where no
offset is desired. This value can be
found in CP-88 (A/D Input Adjusted)
with the dancer pot placed in the zero
(neutral) position.
Enter into CP-76 the percent of full
scale feedback that is desired when
the analog input is at full range.
Enter "1" if the offset is to be added to
and "2" if it is to be subtracted from the
scaled reference.
CP-75 Offset Null
CP-76 Offset Authority
CP-77 Offset Polarity
