6.5 Programmable spindle speed limitation (G25, G26)

6.5 Programmable spindle speed limitation (G25, G26)
Function
The minimum and maximum spindle speeds defined in the machine and setting data can be
modified by means of a part program command.
Programmed spindle speed limitations are possible for all spindles of the channel.
A spindle speed limitation programmed with G25 or G26 overwrites the speed limits in the
setting data and, therefore, remains stored even after the end of the program.
