CP-29 RECOVERY MULTIPLIER
The Recovery Multiplier determines the rate at which the pulse error (position) is reduced to
zero. This parameter multiplied by the pulse error count is the amount by which the speed
setpoint is adjusted every 100 milliseconds.
CP-30 PPR LEAD
PPR Lead (CP-30) is the number of gear teeth or number of encoder lines on the Lead sensor
per revolution (pulses per revolution).
CP-31 PPR FEEDBACK
PPR Feedback (CP-31) is the number of gear teeth or number of encoder lines on the Follower
feedback sensor per revolution (pulses per revolution).
CP-33 MAX RPM LEAD
Measured at the Lead sensor shaft, Max RPM Lead (CP-33) is the maximum RPMs at which the
Lead will operate your system. This number is not to be confused with the full capacity at which
the Lead is capable of running. A system is not generally run at full capacity.
CP-34 MAX RPM FEEDBACK
Measured at the sensor shaft, Max RPM Feedback (CP-34) is the maximum RPMs at which you
want your system to operate and is not to be confused with the full capacity at which your
system is capable of running. A system is not generally run at full capacity. This number is
identical to the maximum operating speed that you set in step 7 of the calibration procedure.
MP-40 TACH
In the Master mode, Tach (MP-40) will display the feedback in Master Engineering Units (CP-20).
In the Follower mode, Tach (MP-40) will display either the E.U.s/Time or the feedback to Lead
ratio in Follower Engineering Units (CP-21), depending on the value in Display Mode Follower
(CP-64). In Jog or the Direct mode, Tach (MP-40) will display the feedback in RPMs. The
feedback is read by the MLP–Trim every ten milliseconds. The readings are summed, then
averaged for one second before the Tach is displayed.
