5 DATA USED FOR POSITIONING CONTROL
Pr.21 Interpolation speed designation method
When carrying out linear interpolation, set whether to designate the composite
speed or reference axis speed.
0: Composite speed .................. The movement speed for the control target is
1: Reference axis speed ........... The axis speed set for the reference axis is
X axis
Designate composite speed
Calculated by AD75
<When composite speed is designated>
Note) For a positioning operation that involves the circular interpolation, specify
the composite speed always.
Pr.22 Current feed value during speed control
When carrying out speed control (including speed control during speed/position
changeover control), set whether to update the " Md.29 Current feed value".
0 : Do not update current feed value ..... The current feed value is not updated.
1 : Update current feed value ................ The current feed value is updated.
2 : Clear current feed value to zero ....... The current feed value is cleared to "0",
