Key statement
The Description of Functions covers the following sub-functions:
• Acceleration
• Jerk
• Kneeshaped acceleration characteristic
Acceleration and jerk
The effective acceleration and jerk can be optimally matched to the machine and machining
situation concerned using axis- and channel-specific programmable maximum values,
programmable acceleration profiles in part programs and synchronized actions, and dynamic
adaptations and limitations.
Kneeshaped acceleration characteristic
The knee-shaped acceleration characteristic means that, in the case of machine axes
featuring a motor (in particular stepper motors) with a torque characteristic that is highly
dependent upon speed, acceleration can be set at the level required to ensure optimum
utilization of the motor whilst at the same time protecting it against overload.
1.2 1.2 Features
Acceleration
Axis-specific functions:
• Programmable maximum acceleration value
• Acceleration profile that can be selected via part-program instruction:
Acceleration without jerk limitation (BRISKA)
• Setting of maximum value using part-program instruction (ACC)
• Specific maximum value for programmed rapid traverse (G00).
• Specific maximum value for traverse with active jerk limitation
• Excessive acceleration for non-tangential block transitions
