and straightness compensation points on a travel axis
Relationship between pitch error compensation points and straightness
compensation points on a travel axis is as follows.
Stored pitch error compensation points on a travel axis
Straightness compensation points on a travel axis
α
: Number of the most distant pitch error compensation point
on the -side of the travel axis(parameter No.3621)
β
: Number of the most distant pitch error compensation point
on the +side of the travel axis(parameter No.3622)
γ
: Number of the pitch error compensation point
of the reference position on the travel axis(parameter No.3620)
δ
: Number of the straightness compensation point
of the reference position on the travel axis
φ
: Number of the most distant straightness compensation point
on the -side of the travel axis(parameter No.13381-13386)
π
: Number of the most distant straightness compensation point
on the +side of the travel axis

  • Page 21. Outline In straightness compensation, compensation data is set as the compensation amounts at the individual compensation points, in the same way as in stored pitch error compensation. This enables fine compensation. Up to six combinations of travel and compensation axes can be used in the straig
