Master Mode

A stand-alone control of a single motor. The scaling format
allows the operator to enter a setpoint in Engineering
Units. The MLP–Trim compares the sensor shaft feedback
to the scaled setpoint and calculates any speed error.
When the MLP–Trim finds speed error, the control algo-
rithm adjusts the Speed Command analog output and
reduces the error to zero.

Master Setpoints

See Appendix C; CP-01 and CP-02.

Max RPM Feedback

See Appendix C; CP-34.

Max RPM Lead

See Appendix C; CP-33.

Mode of Operation

The scaling method that is used to operate your system
(e.g., Direct mode, Master mode, Follower mode, Offset
mode, Inverse Master mode or Inverse Follower mode).

Monitor Parameters

Monitor Parameters (MPs) monitor the performance of the
MLP–Trim and the system which the MLP–Trim is control-
ling. Monitor Parameters also confirm the wiring and the
tuning as well as assist with troubleshooting. MPs can be
accessed at any time during the MLP–Trim's operation,
including during Run, Jog, R–Stop and F–Stop. There are
four categories of Monitor Parameters: Input Monitoring,
Output Monitoring, Performance Monitoring and Status
Monitoring.

Numeric Keys

Use the numeric keys to enter a Parameter Code for either
a Control Parameter (CP) or a Monitor Parameter (MP) or
to enter a value for a Control Parameter. Use the Enter
key after each entry. Use the Clear key to delete your
entry.

Open Loop

A system that is controlled without feedback.

Operating State

The systems status within a mode of operation, such as
Run, R–Stop, F–Stop or Jog.
