¾ Data Number 10 - Calibration Load
The tool load value is set automatically when the tool type is selected. However,
depending on the application characteristics or applications which attach weighted
fixtures on the end of the press ram, the value of the applied load and the load displayed
by the SAN Unit may be mismatched. In this case it is possible to adjust the Full Scale
Load (CAL) value so the displayed load matches the load registered by an external load
cell (Master).
The CAL value can be adjusted up to 10% of the Full Scale Load Value. Use the
following formula on a collection of at least 10 press cycles when a calibration is
necessary.
New CAL value = Master load cell mean/FEC load cell mean * present CAL value
Example: For Tool DTP-501R4
Master Load mean value: 48.0 [KN]
FEC Load mean value: 49.0 [KN]
Present Calibration load: 49.0 [KN]
(48.0 [KN] / 49.0 [KN]) x 49.0 [KN] = 48.0 [KN]
The Calibration load is changed to 48.0 [KN].
¾ Data Number 11 - Final Load High Limit (Methods 2, 3, 4, 6 and 7)
¾ Data Number 12 - Load Low Limit
¾ Data Number 13 - Load High Limit
ƒ Minimum and maximum acceptable limits for Target Load.
In Distance Control, if [13: Load High Limit] is reached before achieving [33: Target
Distance], the press will stop.
When Final Load High Limit is used it acts as the Load High Limit at operation end.
A setting is possible from 0 to 110% of full-scale value.

¾ Data Number 14 - Target Load
ƒ In Load Control Methods, this is the target load value.
(Example: If Target Load is 10KN, press will attempt to operate until 10KN is achieved.)
A setting is possible from 0 to full-scale value.
¾ Data Number 16 – Press Speed 1 Start Load
ƒ The load value at which the speed of the press will change to [53: Press Speed 1].
A setting is possible from 0 to full-scale value.
If Press Speed 1 or 2 Start Load is detected, even if the press has not reached the
Approach Distance, the speed will change to Press Speed 1 or 2.
