Parameter 15: Calibrate valves 1/0
Range : 0-1
Default : 0
Units : -
Function
To adjust the valve offset of the servo valves in the manual mode (not for Hoerbiger hydraulics
application).
Description
For valve types that use the ±10V output of the DM02, there are two ways to adjust the offset:
•
In the diagnostic mode (without using this parameter).
It is possible to adjust the offset of these valves on the valve deflection page in the DM02
module test menu. If the cursor on the screen is set at one of the offsets, it can be adjusted
using the handwheel. The range is between -127 and +127. This corresponds with an offset
in the range between -600 and +600 mV.
•
In the manual mode.
It is also possible to adjust the position of the beam in manual mode with the handwheel. The
best way to do this is during the dwell time (status 4) and by programming a long dwell time.
This adjustment mode must be enabled with this machine parameter.
When you have programmed this parameter to ‘1’, the sofkey ‘Y1/Y2 cal. select’ appears in the
manual mode. With this softkey you select Y1 or Y2 for offset adjustment. The selected side is
highlighted on the service row. The selected side can now be adjusted with the handwheel. The
corresponding valve offset will be memorized in the DM02 when the other side is selected or on
exit of the manual mode.
After the offset adjustment has been finished, this parameter must be reset to zero again.
Press the key
to select the required setting.
Note 1
Offset adjustment for Hoerbiger valves must always be adjusted in the diagnostic program. They
cannot be adjusted with the manual mode.
