4 Explanation of Interface Signals
4.3 PLC Output Signals (Bit Type: Y***)
Cont. Signal name
A Droop cancel request n-th axis
[Function] [Operation]
During the current limit control, the droop generated by the current limit can be released.
[Related signals]
(1) In current limit n-th axis (ILI1 to 8: X900 to 7)
(2) Current limit reached n-th axis (ILA1 to 8: X920 to 7)
(3) Current limit changeover n-th axis (ILC1 to 8: Y9A0 to 7)
(4) Current limit mode 1 and 2 (ILM1,2: YCC0,1)
(5) Current limit changeover (R2593)
Cont. Signal name
A Workpiece coordinate Measurement 2nd axis
[Function] (L system)
The Z axis external workpiece coordinate offset data can be set by cutting the workpiece face with manual operations and
inputting workpiece coordinate measurement 2nd axis.
[Operation]
<Mode selection>
Set the mode selection switch to the manual mode ([Handle], [Jog] or [Rapid Traverse]).
<Tool measurement mode signal input>
Set the tool measurement mode signal to "1".
<Main/sub selection>
Using the tool presetter sub-side valid signal, select whether to measure the workpiece coordinates on the main spindle
side or sub-spindle side.
 Tool presetter sub-side valid signal
OFF: The compensation No. is retrieved from the main spindle side R registers.
ON: The compensation No. is retrieved from the sub-spindle side R registers.
Note
(1) Hold the state of this signal until the measurement with the selected tool is completed.
<Tool selection>
Issue the T command with MDI operation, etc., and select the tool.
Note
(1) Set the selected tool compensation No. in the R register. The set R register differs according to the parameter setting
and the state of the tool presetter sub-side valid signal.
(2) Set the "tool length/wear data" for the tool being used beforehand.

 When the compensation No. is 0, the compensation amount is calculated as "0".
 If the compensation No. exceeds the number of specified offset sets, the "Compensation No. illegal" error occurs.
 Whether to use the main side or sub-side is selected with the tool presetter sub-side valid signal. (OFF: Main side, ON:
Sub-side)
