Detailed Description
2.4 Acceleration margin (channel-specific)
Acceleration (B2)
2-8 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
Functionality
The ACC part-program instruction is used to adjust the maximum acceleration value of a
machine axis.
Axis:
• Value range: Axis identifier for the channel's machine axes
Adjustment factor:
• Value range: 0 < adjustment factor ≤ 200
• Unit: Per cent
Deactivate: ACC[
axis
] = 100
Effective: Modal
Reset response
Acceleration matching is deactivated via a reset, or by setting the adjustment factor to 100%
within the control.
2.4 2.4 Acceleration margin (channel-specific)
2.4.1 Detailed description
2.4.1.1 General information
Key statement
Under normal circumstances, preprocessing makes maximum use of the parameterized
maximum values of the machine axes for the purpose of path acceleration. In order that an
acceleration margin may be set aside for overlaid movements, e.g., within the context of the
"Rapid lift away from the contour" function, path acceleration can be reduced by a
programmable factor. When, for example, a factor of 0.2 is applied, preprocessing will only
use 80% of the maximum possible path acceleration. 20% is set aside as an acceleration
margin for overlaid movements.
