The time the motor takes to make any speed increase is directly proportional to the
value in this parameter.

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.

P.021 Jog Ramp Accel Time

For V/Hz regulation,
this parameter
specifies the amount
of time it takes the
motor to ramp from
zero speed to
Maximum Speed
(P.004) when JOG is
selected.

For vector regulation,
this parameter
specifies the amount
of time it takes the
motor to ramp from
zero speed to Motor
Top Speed (U.017)
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

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.
