4.17 Editing the valve characteristic
● Drive test traversing enable
Here, select whether the drive test to enable traversing should be performed with or
without the PLC.
● Monitoring
Possible settings are:
– Active
– Inactive
● Upper limit / lower limit
Here, enter the upper limit and the lower limit for the axis position.
● Measurement
Possible settings are:
– Characteristic measurement
– Characteristic measurement with identification
Further actions
● Use the "Axis +" / "Axis -" softkeys to change to the next/previous axis.
● Use the "Select axis >" softkey to open a dialog in order to select the axis from a list.
● Use the "Load meas. >" softkey to open a file selection dialog to load a measurement.
The file can contain characteristic data saved automatically or saved manually.
● Use the "Valve parameter >" softkey to open the "Valve characteristic parameters" dialog.
The valve characteristic parameters are displayed there in a list.
● Use the "Calibrate >" softkey to open the "Configuration - calibrate" dialog. You can
calibrate the position of the piston, the pressure and the valve offset there.
● Use the "Measure >" softkey to open the "Measurement" dialog. You can start a
measurement of the valve characteristic there. After the measurement, the measured
characteristic and the characteristic set in the drive are displayed in a diagram (see the
following chapter).
● Use the "Meas. parameters >" softkey to open the "Measurement parameters" dialog.
The measurement parameters are displayed there in a list.

The system monitors that upper and lower limits are complied with. The measurement
is stopped when a limit is violated.
The upper/lower limit is not monitored.
Select this setting when the axis has already been calibrated.
Select this setting if the axis is to be automatically calibrated during the measurement
(see Chapter "Calibration (Page 104)"). Observe the preconditions listed in Chapter
"Calibration (Page 104)". Further, for this measurement, the complete traversing path
must be free. Additional information on the actions (control sense correction, valve
offset correction, piston calibration, ...), which are performed with this measurement, is
provided in parameter p1959 in the SINAMICS S120/S150 List Manual.
