DECELERATION TIME (P.002),

Selects the type of trim mode to be used by the drive:

No Trim

Incremental

Proportional - allows multiple drive sections with a common reference to operate

and ramp

at different values.

Proportional is a type of draw. By using draw, one section can operate 10% faster than an upstream
section. When a ramp occurs on the common reference, the two sections will support the 10% draw
throughout the ramp. S-CURVE ROUNDING will interfere with the ACCELERATION TIME and the
DECELERATION TIME so that the draw will not be constant. Therefore, it is recommended that S-
CURVE ROUNDING be set to 0% if TRIM MODE SELECT is set to PROPORTIONAL. INCREMENTAL
trim is not affected by this limitation.
This parameter also affects how the acceleration and deceleration times are interpreted.

TRIM RANGE (P.109)

Uses the selected trim reference signal to generate draw percentage. Determines how much the trim
signal will affect the drive reference.
