3623 Magnification for pitch error compensation for each axis
NOTE
When this parameter is set, the power must be
turned off before operation is continued.
[Data type] Byte axis
[Unit of data] 1
[Valid data range] 0 to 100
Set the magnification for pitch error compensation for each axis.
If the magnification is set to 1, the same unit as the detection unit is
used for the compensation data. If 0 is set, the same magnification
selected by setting 1 is selected.
3624 Interval between pitch error compensation positions for each axis
NOTE
When this parameter is set, the power must be
turned off before operation is continued.
[Data type] 2-word axis

Rotation axis 0.01 0.001 0.0001 deg
[Valid data range] 0 to 99999999
The pitch error compensation positions are arranged with equal
spacing. The space between two adjacent positions is set for each axis.
The minimum interval between pitch error compensation positions is
limited and obtained from the following equation:
Minimum interval between pitch error compensation positions =
maximum feedrate (rapid traverse rate)/7500
Units:
Minimum interval between pitch error compensation positions:
mm, inch, deg
Maximum feedrate: mm/min, inch/min, deg/min
Example:
When the maximum feedrate is 15000 mm/min, the minimum
interval between pitch error compensation positions is 2 mm.
If setting a magnification causes the absolute value of the
compensation amount at a compensation position to exceed 100,
enlarge the interval between the compensation positions by using a
multiple calculated as follows:
Multiple = maximum compensation amount (absolute value)/128
(Round the remainder up to the nearest integer.)
Minimum interval between pitch error compensation positions
= Value obtained from the above maximum feedrate × multiple
