This push-button initiates the fastening cycle.

wREV (Reverse).

Manual reverse. While this push-button is depressed, the nutrunner turns in the

counter-clockwise direction.
wCAL (Calibration).

CAL voltage checking push-button. Depress this push-button to obtain the CAL voltage
level of the tool pre-amplifier. This level is compared to the data stored in memory. If the
difference is within the allowed range the accept LED will light, otherwise the REJECT LED
will light. The calibration voltage level is converted to the full-scale torque, according to the
parameter setting and is shown in the "DATA" display.

wRESET.

This is used to reset the Axis unit. If this key is pressed during fastening, the process will
stop, and all the fastening data and output signals will be reset. At the same time, the Zero
level of the torque transducer will be checked. If it is within the acceptable range, the
ACCEPT LED will light. If it is not within range, the torque REJECT LED will light.

7.2 Run State Modes.

The AFC 1100 system has two operational states that are controlled by the selection of the
Run/Bypass switch on the front of the Axis unit or by the PLC Bypass input. The operational
modes availible in the Run State are identified below. Under this condition the BYPASS
switch on the front panel is in the RUN position and the BYPASS external signal is not active
(the BYPASS LED is off). During the RUN condition, the display mainly shows the results of
fastening, abnormalities, preset values, etc.

7.2.1 Display indication modes.

Three modes can be selected while in the RUN state by pressing the MODE push-button.
By using the [
parameters may be varied. The displays will remain blank, and mode selection will be

7.2.4 Parameter display mode

Parameter means a group of values that configures a fastening operation. Combined these
values are named preset data. The AFC1100 system can store up to 8 different parameters
that can be selected by WORK SELECT 0 ~ 2 (see section 4.7.2) PLC inputs.

In addition to parameter 1 ~ 8 there is a PARAMETER 0 that contains configuration data
common to all parameters.

7.3 Bypass state operation.

The AFC 1100 system has two operational states that are controlled by the selection of the
Run/Bypass switch on the front of the Axis unit or by the PLC Bypass input. The operational
modes availible in the Bypass State are identified below. Under this condition the BYPASS
switch on the front panel is in the BYPASS position or the BYPASS external signal is active
(the BYPASS LED is on). During the BYPASS condition, the display shows preset values.

7.3.1 Download Mode selection

Immediately after the bypass condition has been entered, the unit is in the download mode,
which allows the system to be set up by a user console via the RS-422 port. Press the
[MODE] key to change from the download mode to the setup mode. If the Axis unit is
performing some data communication to an external computer, the download mode will be
maintained until the operation is completed.

7.3.2 Setup Mode selection

Depressing the Mode button will initiate the Setup mode. Immediately after the setup mode
is established, a blinking number will appear in the [PARM/ABN] display. This number can be

The cursor will appear in the [DATA] display when the machine is in DATA EDIT mode. In
the DATA EDIT mode the MODE key is used as the cursor key. When the MODE key is
pressed, the cursor moves from the 1st data field (at the left) to the 4th data field (right). The

last data field (4th), pressing the MODE key returns the system to the PARAMETER

mode and confirmed with the [SET] key will be displayed.

7.4 Calibration adjustment.

The calibration value is set according to the tool type (capacity). However, depending on
the application characteristics or on the prevailing torque generated by the spindle assembly,
the value of the current torque and the torque display by the Axis unit may mismatch. In this
case it is possible to adjust the FULL SCALE TORQUE (CAL) value, so the displayed torque
matches the real value registered by an external torque transducer (Master).

The CAL value can be adjusted up to ± 10% of the FULL SCALE TORQUE value.

Example:
Let's consider the DFT-801M3-S tool.
Nominal CAL value = 8.0 Kg.m.
Range of adjustment: from 7.2 Kg.m to 8.8 Kg.m.

The torque unit must be the same for all terms.

The FULL SCALE TORQUE value is read from Parameter 1 ~8 D-No 10.

Use the following formula on a collection of at least 10 fastenings when a calibration
correction is necessary:

Chapter 7: System Operations (Rev. 8/98)

New CAL value = Master transducer mean/ FEC transducer mean x Existing CAL
value

If the new CAL value is out of the adjustable range, the [Err] message will be displayed in
the [ANGL/SPNO] display.

Example.



Tool Full Scale value (EXISTING CAL)is 78.4 Nm.
STD torque is 49.0 Nm.
Master transducer mean for 10 piece run is measuring only 47.5 Nm.
FEC transducer mean for 10 piece run is measuring 49.0 Nm.

The new CAL value is obtained as follows:
(47.5/49.0 x 78.4) = 76.0
The FULL SCALE TORQUE (CAL) value must be corrected to 76.0 Nm.
