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
Motor Top Speed
(U.017) to zero
speed when JOG is
selected.
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.
Parameter Range: 1.0 to 999.9 seconds (V/Hz)
0.1 to 999.9 seconds (vector)
Default Setting: 20.0
Parameter Type: Tunable

P.023 MOP Accel/Decel Time
Parameter Range: 0.1 to 999.9 seconds
Default Setting: 20.0
Parameter Type: Tunable

U.017 Motor Top Speed
The MOP (Motor Operated Potentiometer) is a digital reference controlled by the
increment/decrement inputs.
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
Motor Top Speed
(U.017) to zero
speed and from zero
speed to Motor Top
Speed (U.017).
