Outputting Data To Bcd; Using The Comparator - Magnescale LY71 Instruction Manual

2. Applied Operation

2-20. Outputting Data to BCD

When using the BCD unit (LZ71-B) (sold separately), three types of data can be output per unit. Up to two
BCD units can be used.
When using one unit
Three types of data can be output by switching to DRQ1, 2, or 3.
Example:
DRQ1 : 1st axis maximum value
DRQ2 : 2nd axis minimum value
DRQ3 : Current value of 1st + 2nd axis
When using two units
1st axis : Limited to 1st axis data
(The data that can be output are the 1st axis current value, maximum value, minimum value, and
peak-to-peak value.)
2nd axis: Limited to 2nd axis data
(The data that can be output are the 2nd axis current value, maximum value, minimum value, and
peak-to-peak value.)
• The logic for the output data can be set as either positive or negative logic.
• The output format of the data can be selected from three types. (See the BCD Unit (LZ71-B) Instruction
Manual)
For details about the BCD output connection and operation timing, see the BCD Unit (LZ71-B) Instruction
Manual.

2-21. Using the Comparator

When using the comparator unit (LZ71-KR) (sold separately), the preset values and magnitude relationship
are compared, and the display of the judgment result and retrieval of the output signal are possible. Only one
comparator unit can be used.
Comparison objects
1st axis data (current value, maximum value, minimum value, peak-to-peak value), or 1st and 2nd axis
addition data
Selection of the comparison object data
This is selected in the advanced settings.
The judgment results can be held by latch input.
The judgment results are retrieved by signal.
The judgment results can be output by relay signals and open collector signals.
Only one judgment result location is turned on for the relay signals and open collector signals.
For details, see the Comparator Unit (LZ71-KR) Instruction Manual.
