Operation with the Pfeiffer Vacuum parameter set
7.4.1
Factory settings
The electronic drive unit is pre-programmed in the factory. This guarantees proper, reli-
able turbopump operation without the need for additional configuration.
7.4.2
Checking the adjustments
Before operating with parameters, check set values and control commands for their
suitability for the pumping process.
7.4.3
Gas type dependent operations
Friction causes the rotor to heat up severely under gas load and high rotation speed. To
avoid overheating, the electronic drive unit has implemented power-rotation speed-char-
acteristics, whereby the pump can be operated at every rotation speed with the maxi-
mum allowable gas load without danger of damage. The maximum power consumption
depends on the gas type. Three characteristics are available in order to completely ex-
haust the pump's capacity for each gas type.
