(#1552, #1752, #1952, #1553, #1753, #1953, #1410 TO #1473, #1610 TO #1673, #1810 TO #1873)

Item Parameter Description
Compensation #1552 (X) Setting range: 500 to 99999999
Interval #1752 (Y) Setting unit "1" represents 0.001 mm
#1952 (Z)
Compensation #1553 (X) Compensation start point, from Which 64 points, including the start point,
Start Point #1753 (Y) are compensated in + direction.
#1953 (Z) Setting range: -2000000 to 2000000
The minus sign means setting start point in the negative direction from
zero point.
Compensation #1410 to #1473 (X) Setting range: 0to_+127
Amount at Each #1610 to #1673 (Y) Setting unit "1" is 1 pulse (feedback pulse after 4 multipliers). For #1410,
Point #1810 to #1873 (Z) #1610 and #1810, set the pitch error compensation amounts at each com-
pensation start point in incremental value, and thereafter, set the compen-
sation values for 64 points, #1411, #1412-.. #1611, #1612 ... #1811, #1812... in
the + direction in sequence.
Where the measured pitch error is positive, set the compensation
amount in negative, and vice versa.
