Maximum tool speed
System variable $TC_TP_MAX_VELO[<tool number>] can be used to preset a maximum
tool speed (spindle speed).
If no speed limit has been defined, there will be no monitoring.

This address extension specifies which spindle the programmed
cutting rate is to be applied for. In the absence of an address
extension, the rate is always applied to the master spindle.
Note:
A separate cutting rate can be preset for each spindle.

the user will need to select a tool accordingly.
