8.7.2 Percentage velocity correction (VELOLIM)
Function
Using the NC command VELOLIM, the maximum possible velocity of an axis/spindle in axis
operation or the maximum possible gear unit-stage dependent speed of a spindle in spindle
operation - set using machine data - (speed control mode M3, M4, M5 and positioning mode
SPOS, SPOSA, M19) can be reduced in critical program sections, e.g. to reduce the stress
on the machine or to improve the machining quality.
Effectiveness
The function is effective:
● In the AUTOMATIC operating modes.
● on path and positioning axes.
● on spindles in spindle/axis operations
Syntax
VELOLIM[<axis/spindle>]=<value>
