Rockwell Automation Liqui-Flo AC GP Vector Drive Version 6.4 - Manual (Page 110)

4-28 LiquiFlo AC Drive, Software Reference Version 6.4
The MOP (Motor Operated Potentiometer) is a digital reference controlled by the
increment/decrement inputs.
Important: If the drive is powered down and powered back up, the MOP function
reference will always be reset to equal Minimum Speed (P.003).
The MOP provides a digital speed reference that can be increased and decreased
using terminal strip digital inputs.
When the MOP function is set and then disabled by using parameter P.008 (Terminal
Strip Speed Reference Source), the last value in effect prior to the MOP being
disabled will be retained.
P.023 MOP Accel/Decel Time
For V/Hz regulation,
this parameter
specifies the amount
of time it takes the
MOP to ramp from
Maximum Speed
(P.004) to zero speed
and from zero speed
to Maximum Speed
(P.004).
For vector regulation,
this parameter
specifies the amount
of time it takes the
MOP to ramp from
Top Speed (U.017) to
zero speed and from
zero speed to Top
Speed (U.017).
Parameter Range: 0.1 to 999.9 seconds
Default Setting: 20.0
Parameter Type: Tunable

U.017 Motor Top Speed
P.024 MOP Reset Configuration
This parameter
determines when and
if the MOP (Motor
Operated
Potentiometer)
reference is reset to
Minimum Speed
(P.003). Parameter Range: 0 = Reset MOP reference after IET
1 = Reset MOP reference during each stop
2 = Do not reset MOP reference
Default Setting: 0
