Specifications15-615.2 I/O Allocation• In FP7 MC Unit, the I/O signals common to each axis are allocated to the I/O numbers in thefollowing table.• The I/O numbers actually used vary according to the slot number where the unit is installedand the starting word number. Allocation of I/O numbers (Input)I/O no.

If it performs, a warning will occur.ON: Tool operation is being executed, OFF: Tool operation is notexecutedX5 All axes All groups settingdoneMakes axis group setting changes in the unit with the axis group settingrequest contact (Y5) turned ON after making setting changes in the axisgroup with the program. The contact turns ON upon completion of thesetting changes.X6 － (Reserved forsystem) -X7 All axes RecalculationdoneTthe positioning data of the unit memory is restructured by turning onthe recalculation request contact (Y7). This contact turns on after thecompletion of restructuring.If the recalculation request contact (Y7) turns on again, this contact willbe off once.Note) It is used only when the positioning data has been rewritten byladdar programs.X8-XD － (Reserved forsystem) -XE All axes SD memory cardaccess activeTurns on while accessing an SD memory card.ON: Access in progress, OFF: Access stopsXF All axes Initialization doneIndicates that the initial preparation of FP7 MC Unit has beencompleted by reading the setting data from the FROm in the unit whenthe power turns on.ON: FP7 MC Unit preparation done, OFF: FP7 MC Unit in preparation(Note 1): The I/O numbers in the above table show relative addresses based on the base word number. The I/Onumbers actually used vary according to the slot number where the unit is installed and the starting wordnumber.Example) The link establishment flag is X100 for slot number 1 if the starting word is number 10.
