Drive Enable

The Drive Enable output is activated based on the
Ramped Reference (MP-46) and the feedback. The
Ramped Reference is the calculated setpoint that is output
from the Acceleration/Deceleration routine.
See Appendix C; CP-74.

Engineering Units (E.U.)

Master Engineering Units are the units of measure that
your system operates at, such as, RPMs, gallons per hour,
feet per minute. Follower Engineering Units is the number
that will represent the setpoint when the Lead and Follower
are operating at maximum capacity. Refer to Appendix C;
CP- 20 and CP-21.

EEPROM

The EEPROM is where the default Control Parameters are
stored. This is not to be confused with the PROM chip
(which is the software for the MLP-Drive).

F–Stop

One of four operating states. F–Stop brings the
MLP-Drive's drive output to an immediate zero. F–Stop
has priority over the other operating states.

Follower Mode

A complex multi-drive system. The scaling format allows
the operator to enter the setpoint as either a ratio or
percentage. The MLP-Drive compares the setpoint ratio or
percentage to the Follower sensor shaft feedback and
Lead sensor shaft to calculate any speed error. When the
MLP-Drive finds speed error, the control algorithm adjusts
the drive output and reduces the error to zero.

Gain

See Appendix C;CP-65.

Hardwired

Inputs that are wire shorted rather than using push buttons
or switches.
