GV3000/SE AC Bookshelf Drive Software Reference, Version 6.06

See Appendix H for the complete block diagram.

This parameter allows multiple drive sections with a common line reference, but with

different values for draw gain, to run at different speeds depending on the percent

draw.

Note that P.016 affects the accel/decel times. As draw gain increases positive, the

accel/decel time decreases proportionately. As draw gain increases negative, the

accel/decel time increases proportionately. This is based on the following formula:

Modified Accel/Decel = Accel/Decel x [1 / (1.00 + (Draw% / 100))]

P.015 Trim Gain Percentage

This parameter

specifies a

percentage of the

selected trim

reference entering

the speed regulator.

See figure 4.4.

Parameter Range:

-100.0% to +100.0% (1.0 = 1%)
