2.6 Path acceleration for real-time events (channel-specific)
Basic logic functions: Acceleration (B2)

Effective
Effective Real-time event acceleration is only enabled in AUTOMATIC and MDA operating
modes in conjunction with the following real-time events:
• NC-STOP/NC-START
• Override modifications
• Modification of the velocity default for "safely reduced velocity" within the context
of the "Safely Integrated" function
Ineffective Path acceleration for real-time events is ineffective for changes in path velocity that
are attributable to path planning during preprocessing for the channel, such as
contour curvatures, corners, kinematic transformation limitations, etc.
Real-time-event path acceleration is ineffective if the programmed value is smaller
than the path acceleration calculated during preprocessing for the path section
concerned.
