  [Valid data range]  1 to Number of controlled axes 

The unit of some parameters common to all axes such as those for dry 
run feedrate and single-digit F1 feedrate may vary according to the 
increment system. An increment system can be selected by a 
parameter on an axis-by-axis basis. So, the unit of those parameters is 
to match the increment system of a reference axis. Set which axis to 
use as a reference axis. 
 
Among the basic three axes, the axis with the finest increment system 
is generally selected as a reference axis.

  Automatic setting of a coordinate system when the manual reference 

position return is performed 
0:  Not set automatically 
1: Set 

automatically 

 

NOTE 

 

ZPR is valid while a workpiece coordinate system 
function is not provided. If a workpiece coordinate 
system function is provided, making a manual 
reference position return always causes the 
workpiece coordinate system to be established on 
the basis of the workpiece zero point offset 
(parameters No. 1220 to No. 1226), irrespective of 
this parameter setting.

  Local coordinate system when the manual reference position return is 

performed 
0:  The local coordinate system is not canceled. 
1:  The local coordinate system is canceled. 
 

NOTE 

 

ZCL is valid when the workpiece coordinate system 
option is specified. In order to use the local 
coordinate system (G52), the workpiece coordinate 
system option is required.
