Chapter 1 Introduction
PAGE 1-3
1-2. G-System
G type nutrunner is electric motor-driven nutrunner. G type nutrunner fastens bolt
and nut by automatic operation. Integrating main unit functions in conventional spindle
unit, we have made single spindle unit (hereafter referred to as G-Unit) without
distinction of main unit and spindle unit. Reinforcing multi-system control and exterior
communication, we have developed a new fastening system satisfying future-oriented
productive facilities with flexibility. G-System serves dynamic torque control fastening
by combination of servo-motor and torque transducer.
○ Reduced start-up time
G-System does not require complicated ladder of PLC. Easy to understand
parameter setting realizes fastening step entry in this system without special
knowledge. G-System contributes to job improvement in the field.
○ Easy setting change
G-Console, the dedicated software, realizes easy setting of fastening parameter,
fastening objectives and other items.
○ Support diversified external control interfaces
Attach extension unit to G-Unit, and it will support various Fieldbuses controlling
all signal exchange of G-System and external devices.
○ Fastening data saving in CF card
An extension unit saves fastening result and fastening torque waveform in
CF card. Saving data numbers depend upon numbers of G-Unit and
fastening method. As a guideline with 8GB, however, extension unit will
save following data to CF card: 1.8 million cases/spindle, 0.9 million cases/2
spindles, 0.6 million cases/4 spindles, 0.4 million cases/8 spindles, 0.2
million cases/16 spindles and 0.1 million cases/32 spindles.
○ High speed communication with host system
Employment of Ethernet has realized shorter communication hours for data
transmission. G-Type’s dedicated communication method serves 250 times
faster communication speed than our ordinary type.
○ Power source and I/O serving multi-safety
An independent emergency stop signal takes care of interruption during fastening.
Using DC24V as control power, G-Unit communicates its status to host system
despite blackout due to an emergency.
○ Multi-functionalized G-Unit
One G-Unit serves main unit and spindle unit both required by ordinary system.
G-Unit supports Fieldbus specifications and serves space-saving having legacy
spindle function within.

1-3. Functions
(1) Fastening function
G-System offers following fastening methods.
1．Torque method 2．Angle method 3．Plastic area angle
4．Pre-load 5．Pin-hole control 6．Idle check 7．Position adjust
(2) BYPASS (switch off intended spindle) function
PLC I/O BYPASS "ON" or RUN/BYPASS switch set to BYPASS side
G-Unit is BYPASS status with BYPASS LED lighting red. G-Unit will not restart even if
START signal changed OFF to ON under BYPASS status. Fastening is shut-down
during operation once G-Unit came to BYPASS status.
(3) ALARM signal output function
G-Unit outputs ALARM signal if an error was found with the system by SYSTEM
CHECK, CONNECTION CHECK and LOAD CHECK with STATUS LED lighting red
and Display Unit displaying Alarm number and sub code.
(4) Tool type check function
G-Unit verifies if the connected G-Tool agrees with the setting at the time of power ON
and G-Tool replacement. If the verification finds disagreement, ALARM signal 03-02
[Tool type error] takes the place.
(5) Self-check function
Upon switching control power-ON, G-Unit acquires ZERO voltage and CAL voltage of
transducer serving criterion of fastening. Also acquiring these voltages again every
before fastening start, G-Unit conducts self-check comparing these values of switching
on to before fastening start. This self-check is not available for reverse operation.
Change PLC I/O [Auto Z/C Check OFF] to ON, and G-Unit will pass up self-check.
(6) Fastening torque waveform display function
G-Console-developed PC screen displays fastening torque waveform 1980 deg (5.5
turns) retroactive from fastening end or for 40 sec from fastening start.
(7) Error history function
When an error happens with the system together with alarm signal, G-Unit will store
the error contents and history of 500 cases within and 20 cases in G-Tool ID.

Chapter 1 Introduction
PAGE 1-5
(8) Waveform history function
G-Unit retains 100 each OK and NOK fastening result waveform data always. Use
G-Console to read the waveform history.
・Data type :Torque-Angle (540 deg)
・Data contents (OK waveform history) :100 cases from the latest data
※Shut off control power to G-Unit, and the retained data (waveform history) will
disappear.
・Data contents (NOK waveform history) :100 cases of spindle judgment NOK,
ALARM and STOP from the latest data
(9) Fastening result history function
G-Unit retains 12,000 cases fastening result from the latest data. Use G-Console to
read the fastening result history.
G-Unit brought to MASTER (hereafter referred to as Master-Unit) retains not only its
own but also whole multi-system’s other G-Units’ fastening result. Number of
fastening result retained by Master-Unit depends on how many G-Units are under
Master-Unit.
