YASKAWA MOTIONPACK-110 Descriptive Information page 104

• NOTE
1. Using only the integer portions of B/A (or A/B) x 16777216 results in
rounding errors.
2. The value of A/B must be the reciprocal of B/A.
3. When B/A (or A/B) is 1, (that is when the position command unit and
the position detection unit are equal) set the parameters to 16777216.

(2) Influence on Other Parameters
When [-BffA-] ¢ 1 ( _ _ 1), the parameters listed beloware set in the position
detection units. Thus, if the parameters are set based on the position detection units
(0.001 mm), each must be multiplied by A/B for conversion. Integer values are set in the
parameters. Discard the fractions resulting from conversion or count them as a whole
number, as required.
• Backlash offset amount setting (#1405, #1605, #1805)
• Position set area setting (#1406, #1606, #1806)
• Pitch error offset amount setting (#1410-#1473, #1610-#1673, #1810-#1873)
• Reference point return last running distance setting (#1556,.#1756, #1956)
• Servo error area setting (#1555, #!755, #1955)
(Conversion example)
When backlash offset amount is set, backlash distance [0.001 mm] × B/A is set as a
parameter.
