  • Page 33: Set Value Power Consumption

    Operation High gas throughput and high rotation speed lead to strong friction heating of the rotor. To avoid over- heating, power to rotation speed characteristics are implemented in the electronic drive unit. The power characteristic enables the operation of the turbopump at any rotation speed with the maximum permissi- ble gas throughput without thermally overloading the turbopump.

  • Page 34: Rotation Speed Switch Points

    Operation 7.2.4 Rotation speed switch points You can use the rotation speed switch point for the “turbopump operational for the process” message. Exceeding or underrunning the active rotation speed switch point activates or deactivates a signal at the pre-configured output on the electronic drive unit and at the status parameter [P:302]. Rotation speed switch point 1 [P:017] = 0 f (%)

  • Page 35: Rotation Speed Setting Mode

    3. Check the set rotation speed (parameter [P:308] or [P:397]). 7.2.6 Standby Pfeiffer Vacuum recommends standby mode for the turbopump during process and production stops. When standby mode is active, the electronic drive unit reduces the rotation speed of the turbo pump.

  • Page 36: Confirming The Speed Specification

    Fluctuations in the power consumption of idling turbopumps and varying fore-vac- uum pressures of the backing pumps require individual settings of the interval operation. Pfeiffer Vacuum recommends interval operation between 5 and 10 hPa. A pressure gauge and a dosing valve are required to set the switching thresholds.

  • Page 37: Backing Pump Standby Mode

    2. Use this signal for the control of a fore-vacuum safety valve. 7.2.9 Backing pump standby mode In case you are using a Pfeiffer Vacuum backing pump with rotation speed control, this can be used in standby mode by configuring the digital output [P:019] or [P:024]. The power consumption of the turbo- pump has a direct influence on the rotation speed of the backing pump.
