OvrSlw
Feed

S

This is the override for the slow feedrate 
that was set in the machine setup 
parameter ZFirstPickFeedRate_Slow. This 
is used for the same reason as the M cycle 
parameter. This can only be set slower. 
Trying to set this higher will result in the 
software using the original feedrate. 
(Optional)

OvrRPM

R

This is the override for the RPM that was 
set in the machine setup parameter 
calibAndToolMeasurementRPM. This is 
used for the same reason as the M cycle 
parameter. This can only be set slower. 
Trying to set this higher will result in the 
software using the original RPM. (Optional)

Large tools can result in probe damage if the feedrate is 
set too fast. For this reason, the cycle parameters: M, S, 
and R have been added to enable the programmer/
operator to override the values in the machine setup 
parameters for the specific tool being checked or set.

Running this cycle without first initially setting the length 
and diameter offset could result in damage to the probe 
and/or the machine tool. G150 Calibration and G151 
Automatic Tool Length and Diameter set, or G152 Manual 
Tool Length Measure for Special Tools and G153 Manual 
Tool Diameter Measure for Special Tools, must be run first 
before using the G154 cycle.
