Glossary - 10
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 drive 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 ML-Drive 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 ML-Drive is
in R–Stop or F–Stop, however Run cannot be activated
when the ML-Drive is in Jog. Run has the third highest
operating state priority.
Scaling Scaling Control Parameters supply the ML-Drive with the
information that it needs to calculate the ratio of RPM's to
Engineering Units and run at the entered setpoint.
Scroll Up/Down Keys These keys change the active setpoint value even if the
active setpoint is not displayed in the LED display.
Each time you press the Scroll Up key, the active setpoint
will increase by one increment. Each time you press the
Scroll Down key, the active setpoint value will decrease by
one increment. Press and hold the key to automatically
scroll through the increments or decrements .
