6. INTERFACE UNIT
(2) Output circuit
1. Control output
51Ω
Output signal
(GO, -NG, +NG, STS)
GND
• Maximum rating of the output transistor is 30 V, 50 mA.
2. Analog output
560Ω
0V
ALG
• The output voltage range is ±5V.
• The accuracy of the analog voltage output is 0.2% of full-scale range.
• This analog output should be connected to a device that has an input impedance of 1 M
or greater.
If the input impedance is low, the output accuracy will be reduced due to the internally
provided resistance of 560 .
TIP 1. If “Err-0” (specified workpiece not present) occurs, the following remedies are
taken:
• ±NG and GO signals are turned OFF if this error occurs.
• Single-run measurement and zero-run measurement will be terminated without
outputting the results.
• During continuous-run measurement or continuous-run measurement with term
specification ACK remains ON. The measurement can be resumed after “Err-0” is
rectified.
2. Analog signals will be outputted from the following interfaces.
• If a simultaneous measurement is carried out, the analog output of Program Nos.
0 to 4 will be made via the standard interface, and that of Program Nos. 5 to 9 will
be made via the Second Analog I/O Interface.
