This sequence sets the work automatic detection function.
Send Data Word Allocation (3rd Operand of PMCR(260))
Receive Data Word Allocation (4th Operand of PMCR(260))
None.
Additional Information
•
This sequence cannot be used when DIP switch SW3, pin 5 of the Laser Micrometer is not
turned ON.
•
The detection lower and upper limit must be set with 3 digits for the integer portion and 4 digits
for the decimal portion.
This sequence releases the setting of work automatic detection function.
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
Receive Data Word Allocation (4th Operand of PMCR(260))
None.
