4.6.4 Second Menu Vector Parameter Descriptions (U.000 to U.048)

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 (0.5 ms) 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 = %torque reference

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

*

If the AutoMax Network option is used, see P.063.

Default Setting:

0

Parameter Type:

Configurable
