Question number FAQ-0115

Connection between GS/BS series sensor and RV-3150 reversible counter.

This document describes the wiring for connecting the GS/BS series sensor to the RV-3150 reversible counter, as well as the setup procedure on the RV-3150 side. Please have the RV-3150 manual ready.

1. Wiring Diagram

The relay cable is available as an option.

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

The signals from the GS/BS series are square wave (voltage) output signals, so in the RV-3150's "parameter setting function," you will configure the sensor input channel as follows.

SENSOR CH SET
0 P-IN

3. Sensor type setting (factory setting 0 DUAL)

The signal of the GS/BS series is a two-phase square wave (voltage) output signal, so in the sensor type setting of the RV-3150's "parameter setting function," it should be configured as described below.

SENSOR TYPE SET
0 DUAL

4. Multiplication setting (default at shipment 2 * 4)

When connecting to the GS/BS series, set the multiplication factor to 4 in the 'parameter setting function' of the RV-3150 as shown below.

PULSE MULT SET
2 * 4

5. Counting method setting (at the time of shipment 0 (+))

When counting the push of the spindle from the GS/BS series as a positive (+) count, set the counting direction in the "parameter setting function" of the RV-3150 as follows.

SENSOR DIR SET
0 （+）

6. Decimal point position setting (Factory setting 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

<Resolution of 10 μm>

D.POINT SET
2 0.00

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

When connecting to the GS/BS series, set the count value corresponding to the full-scale value of the analog voltage output (F.S. value: 10 V) in the "parameter setting function" of the RV-3150.

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

ANALOG FS SET
FS →030000

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

ANALOG FS SET
FS →003000

Output update time	within 15 ms
Resolution	12-bit D/A method Stroke 50 mm Type 1μm unit: 25 μm = 5 mV output Stroke 13 mm Type 10 μm unit: 10 μm = 5 mV output
linear error	±0.3 %/F.S.

8. calibration Signal output settings

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

If you want to output a full-scale value at 10 V.

CAL SET
1 +FULL

9. Refer to the RV-3150 manual for the following settings as necessary.

Index Setting
Comparator Condition Setting
Offset value setting
LCD upper/lower section display item settings
Ratio calculation function ON/OFF
BCD Output Logic Settings
RS-232C baud rate setting
LCD backlight lighting method setting
