4-28 GV3000/SE AC Bookshelf Drive Software Reference, Version 6.06
The time the motor takes to make any speed decrease (except a coast-to-rest stop) is
directly proportional to the value in this parameter.
The MOP (Motor Operated Potentiometer) is a digital reference controlled by the
increment/decrement inputs.
P.022 Jog Ramp Decel Time
For V/Hz regulation,
this parameter
specifies the amount
of time it takes the
motor to ramp from
Maximum Speed
(P.004) to zero speed
when JOG is
selected.
For vector regulation,
this parameter
specifies the amount
of time it takes the
motor to ramp from
Top Speed (U.017) to
zero speed when
JOG is selected.
Parameter Range: 1.0 to 999.9 seconds (V/Hz)
0.1 to 999.9 seconds (vector)
Default Setting: 20.0
Parameter Type: Tunable
Refer also to parameters: P.004 Maximum Speed
P.025 Stop Type
U.017 Motor Top Speed
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
