14 PLC Help Function
14.12 Chopping
Chopping control data
Rn is specified with the PLC device (chopping control data address).
Data to be used differs depending on whether the compensation value sequential update method is applied or compensation
amount fixed method is applied.
Update : Specify with the compensation value sequential update method
Fixed : Specify with the compensation value fixed method

Control status
bit3 : Chopping start ready completion
This turns OFF at the falling edge of the chopping parameter valid signal.
bitF : Error occurred
This turns ON if an alarm occurrs when the chopping parameter valid signal is turned ON. The details
of error is notified with bit9 to C. (*1)
bit9 : Chopping error
bitA : Chopping specifications is not available
bitB : Compensation method is set to other than 0/1
bitC : Multiple chopping axes are specified
Not used
Compensation method
0000(HEX) : Compensation value sequential update method
0001(HEX) : Compensation value fixed method
The setting unit for the chopping
override
0000(HEX): 1 % (unit)
0001 (HEX): 0.01 % (unit)
Rapid traverse override valid/invalid (Rn+4)
This sets the rapid traverse override valid/invalid in respect to the movement speed between the basic
position and the upper dead center point.
0 : Invalid
1 : Valid
Chopping axis designation
bit0: 1st axis Select any one of the existing axes using bit.
bit1: 2nd axis When no axis is specified, the axis whose base specification parameter
: : "chop_ax" is "1" (the smallest No. of axis) within the same part system is
bit7: 8th axis selected.
bit8 to F: Not used (Set to "0".)
Upper dead center point
Set the movement amount of basic position -> upper dead center point with the code.
Use the setting and display unit (#1003 iunit) for setting.
Bottom dead center point
Set the distance of upper dead center point -> bottom dead center point with the code.
Use the setting and display unit for setting.
Number of cycles
This sets the number of cycles for chopping cycle. (Unit: Number of cycles/min)
Operation mode with the compensa-
tion value fixed method
0000(HEX) : Playback mode
0001(HEX) : Record mode
Data No.
This specifies what number data (n-th data) from the head of the record area (specified by the param-
eter) to be used. (Both the record mode and playback mode must be specified. 1st data area is specified
with 0.)
