7 Parameter set
7.1 General
All variables of the vacuum pump relevant for the function are stored as parameters in the electronic
drive unit. Each parameter has a three-digit number and a description. Parameters can be used via
Pfeiffer Vacuum display and control panels or via RS-485 with the Pfeiffer Vacuum protocol.
Conventions
Parameters are printed in bold as
three-digit numbers
in
square brackets
. The designation can also
be specified.
Example:
[P:312]
Software version
Factory settings
The electronic drive unit is pre-programmed in the factory. This makes a more direct and safe operation
of the vacuum pump possible without additional configuration.
You can configure the following parameters for the specific process:
●
[P:026]
: rotation speed setting mode on/off.
●
[P:707]
: specification of the rotation speed setting mode with 30 to 170 % of the nominal rotation
speed.
●
[P:002]
: stand-by mode on/off.
