9.1.2 I/O Terminal Operations

1 7-level comparator output (terminals 1 to 14)

The LS-5000 series performs comparator output (

➮

See p. 35

) for the output

number specified during the I/O slot setup (

➮

See p. 59.

) procedure.

Note: When Pitch mode is selected, the comparator output is as follows:

HI3: Turns ON when the target’s actual number of pitches is different from the

preset number of pitches.

HI2: Unused

HI1: Turns ON when the measured value exceeds the preset upper/lower limits.

GO: Turns ON when the measured value is within the tolerance range.

LO1:Unused

LO2:Unused

LO3:Unused

2 Self-timing output (terminals 15 and 16)

In self-timing mode, the output specified during the I/O slot setup procedure turns

ON when the self-timing signal turns ON. The self-timing output is a one-shot

signal, as shown below:

➮

See p. 59 for I/O slot setup.

3 Timing input (terminals 19 and 20)

When this terminal and the GND terminal are short-circuited, the LS-5000 series

performs the measuring mode operation for the output number specified during the

I/O slot setup procedure.

➮

See p.46 for measuring mode and p.59 for I/O slot setup.

4 Reset input (terminals 21 and 22)

When this terminal and the GND terminal are short-circuited, the LS-5000 series

performs the measuring mode operation for the output number specified during the

I/O slot setup procedure.

➮

See p.46 for measuring mode and p.59 for I/O slot setup.

5 Auto-zero input (terminals 23 and 22)

When this terminal and the GND terminal are short-circuited, the LS-5000 series

instantaneously resets the measured value to “0.00000” for the output number

specified during the I/O slot setup procedure.

➮

See p.59 for I/O slot setup.

6 Analog output

The LS-5000 series performs analog output in the range of ±10 V for the output

number specified during the I/O slot setup procedure.

➮

See p.57 for analog output and p.59 for I/O slot setup.
