GV3000/SE 230 VAC Drive, Software Reference Version 6.04
If U.000 = 0, the drive will always regulate speed.
If U.000 > 0, the drive will regulate torque or speed. Torque or speed regulation is
selected by a terminal strip digital input (see the P.007 configuration) or the network
option board (depending on the control source).
If torque regulation is selected:
• the Current Limit parameter (P.005) is not applied.
• asserting the START input when JOG is selected will enable the torque
regulator, not the speed regulator (i.e., P.020, P.021, and P.022 are not used).
• the stop type will always be coast-to-rest regardless of the value in P.025 (Stop
Type).
If U.000 = 1, the analog input conditioning (P.009 through P.011) does not apply.
The analog input in this case is converted every torque regulator scan (0.5ms) for
external closed-loop control (e.g., positioning applications using the QUIQ module).
If U.000 = 3:
• The FWD/REV input can be used to invert the selected speed reference when it
is used as the torque reference.
• If the speed reference is used as the torque reference, the %torque is computed
as
Speed value x 150
U.017 (Top Speed)
This assumes that P.028 = U.017.

U.000 Torque Reference Source
This parameter
specifies the source
for the torque
reference when
torque regulation is
selected.
Parameter Range: 0 = Speed loop output
1 = Terminal strip analog input
2 = Option port (network torque reference register)*
3 = Selected speed reference
Default Setting: 0
Parameter Type: Configurable
