4. DESCRIPTION OF PARAMETERS
405
7956
Number of α–axis interaction gears
7957
Number of β–axis interaction gears
[Data type] Byte
[Valid data range] 0 to 127
When the actual number of gears exceeds the valid data range, set the
values obtained by dividing the number of α axis gears and the number of
β axis gears by the greatest common measure of the two numbers.
Example: When the number of α axis gears is 300, and the number of
β axis gears is 200
Set 3 for parameter No.7956, and 2 for parameter No.7957
because 300:200 = 3:2.
From the number of α axis interaction gears and the number of β axis
interaction gears, a β axis synchronous rotation compensation value is
calculated, and a command based on the calculated value is automatically
sent for the β axis.
β axis synchronous rotation compensation value = (α axis rotation amount) (number of β axis synchronous rotation gears)/
(number of α axis synchronous rotation gears)
