e. MAX AIR PRESSURE
Used when FORCE CONTROL MODE is 1 to 3.
Set the maximum pneumatic pressure supplied to the electro pneumatic proportional valve.
f. MAX FORCE
Displays the maximum force of the set electro pneumatic proportional valve.
g. CALIBRATION CONSTANT FORCE
Used when FORCE CONTROL MODE is 1, 3 or 4.
FORCE CONTROL MODE is 1 or 4:
Set the force output to the electro pneumatic proportional valve (ANALOG OUT) after the
completion of welding sequence.
FORCE CONTROL MODE is 3:
Set the force output to the electro pneumatic proportional valve (ANALOG OUT) Regardless of
welding sequence operation.
UP and DW at the left side of CALIBRATION CONSTANT FORCE can be used when FORCE
CONTROL MODE is 3. The force can be checked with this setting when FORCE CONTROL
MODE is 3.
Set AIR CYLINDER DIAMETER and MAX AIR PRESSURE. When there is difference
between the set value and the measured value, adjust either AIR CYLINDER DIAMETER or
MAX AIR PRESSURE so that the set value and the measured value become the same.
Set the force used to CALIBRATION CONSTANT FORCE. The force is applied by changing
UP on the left side of CALIBRATION CONSTANT FORCE into DW and released by returning
the setting to UP. The force setting and the force can be checked by measuring the force while
the force is applied.
h. CALIBRATION LOW
i. CALIBRATION HIGH
Used when FORCE CONTROL MODE is 4.
Set CALIBRATION LOW and HIGH to set the maximum force.
UP and DW on the left side of CALIBRATION LOW and HIGH can be used when FORCE
CONTROL MODE is 4.
The force can be checked with these settings when FORCE CONTROL MODE is 4.
The force is applied by changing UP on the left side of CALIBRATION LOW into DW and
released by returning the setting to UP. About 30% of the maximum force is applied.
Measure the force while the force is applied, and input the measured value in CALIBRATION
LOW. The force is applied by changing UP on the left side of CALIBRATION HIGH into DW
and released by returning the setting to UP. About 80% of the maximum force is applied.
Measure the force while the force is applied, and input the measured value in CALIBRATION
HIGH.
