Question number FAQ-0115

Connecting GS/BS series sensors to the RV-3150 reversible counter.

This document describes the wiring and setup procedures for the RV-3150 when connecting a GS/BS series sensor to an RV-3150 reversible counter. Please have your RV-3150 instruction manual handy.

1. Wiring Diagram

* Extension cables are available as an option.

2. Sensor input channel setting (default: 0 P-IN)

Since the GS/BS series signals are square wave (voltage) output signals, set the sensor input channel setting in the RV-3150's "Parameter Setting Function" as follows:

SENSOR CH SET
0 P-IN

3. Sensor type setting (default: 0 DUAL)

The GS/BS series signals are two-phase square wave (voltage) output signals, so set the sensor type setting in the "Parameter Setting Function" of the RV-3150 as follows.

SENSOR TYPE SET
0 DUAL

4. Multiplier setting (default: 2 * 4)

When connecting to the GS/BS series, set the multiplier setting in the "Parameter Setting Function" of the RV-3150 to 4x as shown below.

PULSE MULT SET
2 * 4

5. Counting method setting (default: 0 (+))

To define a positive (+) count as when the spindle of the GS/BS series is pushed in, set the counting direction setting in the "Parameter Setting Function" of the RV-3150 as follows:

SENSOR DIR SET
0 （+）

6. Decimal point position setting (default: 0 OFF)

When connecting to the GS/BS series, set the decimal point position in the "Parameter Setting Function" of the RV-3150 as follows:

<In the case of a resolution of 1 μm>

D.POINT SET
3 0.000

<For a resolution of 10 μm>

D.POINT SET
2 0.00

7. Analog output full-scale setting (default FS → 999999)

When connecting to the GS/BS series, set the count value corresponding to the full-scale value (FS value: 10 V) of the analog voltage output in the "Parameter Setting Function" of the RV-3150.

<If you want the full scale value to be 30 mm (measurement unit: 1 μm)>

ANALOG FS SET
FS →030000

<If you want the full scale value to be 30 mm (measurement unit: 10 μm)>

ANALOG FS SET
FS →003000

Output update time	Within 15 ms
Resolution	12 bit D/A method For a 50 mm stroke type with 1 μm increments: 25 μm = 5 mV output. For a 13 mm stroke type in 10 μm units: 10 μm = 5 mV output
linearity error	±0.3 %/F.S.

8. calibration signal output settings

When calibration the output voltage, set it as follows. After calibration is complete, be sure to return it to 0: ZERO.

■If you want to output the full-scale value at 10 V

CAL SET
1 +FULL

9. If necessary, configure the following settings by referring to the RV-3150 instruction manual.

Setting Index Setting
Comparator Condition Setting
Offset value setting
LCD Upper/Lower Display Item Settings
Ratio calculation function ON/OFF
BCD Output Logic Settings
RS-232C baud rate setting
LCD backlight illumination method setting
