Error status (in playback mode)
bit0 : This is turned ON when the difference between the motor side feedback amplitude width and the
commanded width has exceeded the tolerance set with the parameter (#2080 chwid).
Chopping compensation amount record comple-
tion status (in record mode)
bit0 : "1" at completion of recording
bit1 : "1" when recording is not completed
Command - Feedback
[In playback mode]
Difference between the motor side feedback amplitude width and the commanded width is stored when
the difference has exceeded the tolerance set with the parameter (#2080 chwid).
[In record mode]
Difference between command and feedback is stored every time the compensation amount is calculated.
Rapid traverse override valid/invalid
Set the rapid traverse override valid/invalid in respect to the movement speed between the basic position
and 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 se-
bit7: 8th axis lected.
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
Compensation amount (Width)
Compensation amount to be added to the chopping upper/bottom dead center point command.
In the playback mode, this is used for amplitude compensation.
When started with the record mode, this is automatically stored.
Compensation amount (Center)
Compensation amount to be added to the chopping upper/bottom dead center point command.
In the playback mode, this is used for compensating the center of amplitude.
When started with the record mode, this is automatically stored.
Data to be opened
Use this for managing the compensation amount record area, etc. by using ladder of the user.
