7.5.1 Saving Parameter Values
The E-871.1A1N is configured via parameters, e.g., for adapting to the connected positioner.
The parameter values can be saved to a text file so that they cane be restored at a later time.
Information
Changing parameter values can cause undesirable results.
►
Create a backup copy on the PC before changing the parameter settings of the
E-871.1A1N. You can then restore the original settings at any time.
►
Create an additional backup copy with a new file name each time after optimizing the
parameter values or adapting the E-871.1A1N to a particular positioner.
Parameter values saved in a text file on the PC can be loaded back to the E-871.1A1N in
PIMikroMove or PITerminal. The
Send file...

command window. Before loading into the E-871.1A1N, the individual lines of the text files
must be converted into command lines that contain the corresponding SPA or SEP
