of tool standard Full Scale Torque
Set the Full Scale Torque value of the connected tools.
The calibration value is set according to the tool type (capacity). However, depending on the application
characteristics or the prevailing torque generated external to the tool output shaft, the value of the applied
torque and the torque display by the MFC controller may not match. In this case, it is possible to adjust
the FULL SCALE TORQUE (CAL) value so the displayed torque matches the installation torque
registered by an external torque transducer (Master).
New Full Scale Torque value
＝
Mean Torque from an external Torque Transducer (Master) ÷ Mean Torque from FEC
Transducer × Existing Full Scale Torque
Ex
：
D-No.100 [Full Scale Torque]
：
294.2Nm
Mean FEC Torque
：
200.0Nm in this case
Mean Master Torque
：
210.0Nm
210.0Nm ÷ 200.0Nm × 294.2Nm = 308.9Nm
The Full Scale Torque should be changed to 308.9Nm.
・
If the Full Scale Torque calibration needs to be changed, the mean of the
fastening result data is used as the measured value.
(The number of samples of fastening result data is recommended to be at
least 10 as a statistical standard.)
・
When the calibration value is changed, confirm that other torque parameters
are lower than the new Calibration value (or the new CAL value may not be
able to be entered) Other torque related parameters should be set lower
than the tool’s max torque value and Full Scale Torque.
・
ANY CHANGES TO THE CALIBRATION TORQUE SHOULD BE DONE BY
QUALIFIED PERSONNEL ONLY (output torque results may differ if not
correctly changed)
D-No.101 Peak Torque Low Limit [Nm] D-No.102 Peak Torque High Limit [Nm]
Setting Range
：
0
～
D-No.100 [Full Scale Torque] ×1.1
Set points for the high/low limits of the fastening torque.
If the fastening torque exceeds the D-No.102 [Peak Torque High Limit] or does not reach the D-No.101
[Peak Torque Low Limit], the fastening judgment will be REJECT.
D-No.103 Standard Torque [Nm] Setting Range
：
0
～
D-No.010 [Full Scale Torque]×1.0
Set point of the fastening standard (Target) torque.
This function is only available when the D-No.000 [Fastening Type] is Torque Control Method
Ex.: If 10.0 is set, the controller attempts to fasten until the torque value 10.0[Nm] is reached.
