PPR Lead See Appendix C; CP-30.
Tuning Tuning stabilizes speed error differences between the
setpoint and feedback.
Ring Kits Ring Kits are flange motor mounted sensors that measure
the pulses per revolution (PPR) of the motor shaft.
R–Stop One of four operating states. R–Stop uses Deceleration
Rate (CP-17) to decelerate the Speed Command (analog
output) to zero. R–Stop has the second highest operating
state priority.
RAM Test Tests Random Access Memory. This test can be run as
part of the diagnostic tests. It is also one of the two power
up diagnostic routines that the MLP–Trim automatically
performs during every Power Up.
RPM Feedback The speed of the feedback sensor in revolutions per
minute.
RPM Lead The speed of the lead sensor in revolutions per minute.
Run One of four operating states. Run ramps to the scaled
setpoint speed using the acceleration and deceleration
rate values in Acceleration Time (CP-16) and Deceleration
Time (CP-17). Run can be activated when the MLP–Trim
is in R–Stop or F–Stop, however Run cannot be activated
when the MLP–Trim is in Jog. Run has the third highest
operating state priority.
Scaling Scaling Control Parameters supply the MLP–Trim with the
information that it needs to calculate the ratio of RPM's to
Engineering Units and run at the entered setpoint.
