[Pr.402] Composite main shaft gear
Set the composite method for input values from the main and sub input axes. The setting values for each axis are shown as
follows.
Setting value
0: No input
1: Input+
2: Input-
Operation assumes "0: No input" if the value is set out of the range from 0 to 2.
The composite method for the composite main shaft gear can be changed during synchronous control. It is
used as a clutch to switch input values between the main and the sub input axes.
[Pr.403] Main shaft gear: Numerator, [Pr.404] Main shaft gear: Denominator
Set the numerator and the denominator for the main shaft gear to convert the input value. The input value is converted as
follows.
Input value after conversion = Input value before conversion ×
The input value direction can be reversed by setting a negative value in the numerator of the main shaft gear.
Set the denominator of the main shaft gear to a value within the range from 1 to 2147483647.
Ex.
Convert the cam axis per cycle to be controlled in intervals of 0.1mm (0.00394inch). The cam axis synchronizes with a
conveyor that moves 100mm (3.937inch) for every (360.00000degree) of the main shaft.
"[Pr.403] Main shaft gear: Numerator": 1000[0.1mm]
"[Pr.404] Main shaft gear: Denominator": 36000000[10
Details
The input value from the input axis is calculated as 0.
The input value from the input axis is calculated as it is.
The input value from the input axis is calculated with its opposite sign.
