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 Configuration - reference variables

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. whe

n recording a trace).
