Configuration - reference variables

The reference variables are calculated once at the first commissioning of the drive. The
reference variables are not dependent on the parameter set. You can define as to whether
reference variables should be automatically preassigned using parameter p0340.0.
Figure 4-20
In order to prevent reference values being calculated, activate the checkbox "Inhibit
automatic reference value calculation".
In this dialog you define reference variables for velocity, pressure, force, power, angle and
acceleration.
The reference variables also act as limits. If this range is not sufficient, you must adapt the
reference variables manually.
The reference variables act as scaling between the NC and drive for actual value sensing,
setpoint output as well as for measuring functions. All specified relative values, e.g. for the
trace, refer to these reference variables.
Save the reference variables with the "OK" softkey. Then return to the overview page.
Note
If you are working with different DDS with different valve characteristics, the reference
variables remain the same as these are not switched over with the DDS. You must take the
resulting conversion factor into consideration (e.g. when recording a trace).
