CONTREX ML-Drive - Manual (Page 127)

Glossary - 7
Master Mode A stand-alone control of a single motor. The scaling format
allows the operator to enter a setpoint in Engineering
Units. The ML-Drive compares the sensor shaft feedback
to the scaled setpoint and calculates any speed error.
When the ML-Drive finds speed error, the control algorithm
adjusts the drive 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, Inverse
Master mode or Inverse Follower mode).
Monitor Parameters Monitor Parameters (MPs) monitor the performance of the
ML-Drive and the system which the ML-Drive is controlling.
Monitor Parameters also confirm the wiring and the tuning
as well as assist with troubleshooting. MPs can be ac-
cessed at any time during the ML-Drive'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.
Output Monitoring Drive Output (MP-47)
Logic Outputs (MP-56)
