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

For the rotation axis
•

•

•
No. of the compensation position of the reference position: 60
If the above is specified, the No. of the farthest compensation position
in the negative direction for the rotation axis is always equal to the

The No. of the farthest compensation position in the positive direction
is as follows:
No. of the compensation position of the reference position +

The correspondence between the machine coordinate and the

The compensation value is output at the circled position.
If the sum of the compensation value from 61 to 68 is not zero, the

spindle control in the connection manual (function
part).
Type M:
The CNC determines a proper gear from the
parameter setting and S command value, and
requests the PMC to specify the gear and its
switching.
In addition, spindle control is exercised according
to a gear selected by the CNC.
Type T:
The CNC exercises spindle control according to a
gear selected by the PMC.

When the constant surface speed control option is
selected, type T is selected, regardless of whether
this parameter is specified.
