CRS

  In tool center point control, when the deviation from the path during 

movement at the specified cutting feedrate or rapid traverse rate is 
determined to exceed the limit: 
0:  The feedrate or rapid traverse rate is not decreased. 
1:  The feedrate or rapid traverse rate is controlled so that the limit 

of the deviation from the path set in the parameter for the cutting 
feed or rapid traverse is not exceeded. 

When this parameter is set to 1: 
In the rapid traverse mode, the rapid traverse rate is decreased so that 
the deviation from the path does not exceed the limit specified in 
parameter No. 19751. 
In the cutting feed mode, the cutting feedrate is decreased so that the 
deviation from the path does not exceed the limit specified in 
parameter No. 19752.

Limit of the deviation from the path (for rapid traverse) 

 

 

[Input type]  Parameter input 

 

[Data type]  Real path 

 

[Unit of data]  mm, inch (machine unit) 

 

[Minimum unit of data]  Depend on the increment system of the reference axis 

 [Valid data range]  9 digit of minimum unit of data (refer to standard parameter setting 

table (A))   
(When the increment system is IS-B, -999999.999 to +999999.999) 
This parameter sets the limit of the deviation from the path in the rapid 
traverse mode in tool center point control. 
If the tool moves at the specified rate, the deviation from the path may 
exceed the value specified in this parameter. In this case, the rate is 
decreased so that the tool moves along the path. 
This parameter is valid when bit 6 (CRS) of parameter No. 19746 is 
set to 1. 
When 0 is set, the least input increment is assumed to be the limit of 
the deviation from the path. 
If a negative value is set, the rapid traverse rate is not decreased. 
 

NOTE 

 

The error generated after the rate is decreased 
may be smaller than the value set in this parameter 
depending on the calculation error.
