AC - Acceleration
Purpose:
Defines the maximum acceleration in counts/second
2
. This parameter is used in speed
mode (UM=2) and position control modes (UM=3, 4, 5) in PTP (PA, PR) and jogging
(JV) reference modes.
The AC parameter does not affect the present motion. It is used for planning the next
motion, which is initiated by a BG command.
If AC is smaller than SD, the maximum possible acceleration will be limited to
SD and the value of AC will be ineffective.
