Figure X.1 Speed Profile
INTEGRAL
Low Acceleration (LA) is the rate at which the speed increases from the
minimum (dL) until either High Speed or the target position is reached.
Values from 1 to 99 may be selected. Recommended initial settings
are shown in Figure X.2. The effect of this parameter on performance
is indicated in Figure X.3.
Acceleration Breakpoint (Ab) specifies the position at which the actua-
tor will start accelerating from the minimum speed(dL). This position
is the difference between the current position and the target position.
Values from 0.1% to 5.0% difference may be selected. Recommended
initial settings are shown in Figure X.2. The effect of this parameter
on performance is indicated in Figure X.3.

Low Acceleration and Accelera-
tion Breakpoint provide different
features for the B and C size power
modules. See section 6.3.2.
A specific installation, low dead-
band or specialized control criteria
may require adjustment to the initial
settings.
