Rockwell Automation GV3000/SE 230VAC 1-20 HP GP & Vector Drive Ver. 6.04 Software Start-Up and Ref. - Manual (Page 95)

4-9 Programming Reference
This parameter limits
the speed reference
to the drive.
Regardless of what
speed reference is
supplied, the
regulatot will not
command a speed
greater than the
value in P.004.
P.003 Minimum Speed
This parameter limits
the speed reference
to the drive.
Regardless of what
speed reference is
supplied, the
regulator will not
command a speed
less than the value in
P.003. Parameter Range: 0.5 to P.004 Maximum Speed (V/Hz)
0 to P.004 Maximum Speed (vector)
Default Setting: 5.0 Hz (V/Hz)
150 RPM (vector)
Parameter Type: Tunable
Refer also to parameters: P.004 Maximum Speed
ATTENTION: The drive can operate at and maintain zero speed.
The user is responsible for ensuring safe conditions for operating
personnel by providing suitable guards, audible or visual alarms, or
other devices to indicate that the drive is operating or may operate at
or near zero speed. Failure to observe this precaution could result in
severe bodily injury or loss of life.
Note that in V/Hz regulation, the drive may decrease the output frequency below
P.003 (but not below 0.5 Hz) to avoid an overcurrent fault.

P.004 Maximum Speed
Parameter Range: 15.0 to H.022 Overfrequency Limit (V/Hz)
10 RPM to U.017 Motor Top Speed (vector)
Default Setting: 60.0 Hz (V/Hz)
1722 RPM (vector)
Parameter Type: Tunable
Refer also to parameters: P.028 Speed Display Scaling
H.022 Overfrequency Limit
U.017 Motor Top Speed
ATTENTION: The user is responsible for ensuring that driven machinery,
all drive-train mechanisms, and application material are capable of
safe operation at the maximum operating speed of the drive.
Overspeed detection in the drive determines when the drive shuts
down. For vector regulation, this is factory-set to 130% of maximum
speed. For volts/hertz regulation, this is fixed at the frequency level
set in parameter H.022 (Overfrequency Limit). Failure to observe this
precaution could result in bodily injury.
For V/Hz regulation, this parameter specifies the maximum allowed speed in hertz.
The drive is equipped with configurable overspeed protection at the frequency level
set in H.022 (Overfrequency Limit).
For vector regulation, this parameter specifies the maximum allowed speed in RPM.
This drive is equipped with fixed overspeed protection at 130% of Maximum Speed.
