Mean value of the feed-rate minimum values during cutting in

Based on the mean value you obtain a meaningful tendency for

F-min (tool wear), and not only an individual instantaneous

Maximum recorded spindle power during machining. The TNC

shows the value as a percent of the spindle's rated power.

Reference load of the spindle. The TNC shows the value as a

percent of the spindle's rated power.

Reaction by the iTNC to overload:

M: Perform an NC-function macro defined by the OEM

S: Immediately perform an NC stop

F: Perform an NC stop once the tool has retracted

E: Only display an error message on the screen

–: Do not perform an overload reaction

The iTNC conducts a shutdown response if the maximum

spindle power is exceeded for more than one second and at

the same time the feed rate falls below the minimum you

Block number at which the machining cut begins.
