Rockwell Automation GV3000/SE AC Gen. Purpose and Vector Drive Software Start-Up and Ref. Manual - Manual (Page 113)

Programming Reference 4-27
Jog reference is independent of any other speed reference. Unlike the run speed
reference, the jog speed reference cannot be adjusted using the ▲ or ▼ keys.
The time the motor takes to make any speed increase is directly proportional to the
value in this parameter.
P.020 Jog Speed Reference
This parameter is the
speed reference for
the drive when JOG
is selected.
Parameter Range: Minimum Speed (P.003) to Maximum Speed (P.004)
Default Setting: 5.0 Hz (V/Hz)
150 RPM (vector)
Parameter Type: Tunable
Refer also to parameters: P.003 Minimum Speed
P.004 Maximum Speed
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
Refer also to parameters: P.004 Maximum Speed
U.017 Motor Top Speed
