There are three types of axis acceleration/deceleration available:
Exponential Acc/Dec
Uniform or Linear Acc/Dec
S--Curve Acc/Dec
These are used to produce smooth starting and stopping of the machine’s
axes and prevent damage to the machine resulting from harsh movements.
Your system installer determines the acc/dec parameter type (exponential
or linear) for some manual motion types. To determine which motion
types a re configurable, refer to the following table. Refer to your system
installer’s documentation for more information about how your system is
configured.
Refer to the table below to determine the type of acceleration/deceleration
performed for manual motion and programmed moves.
