17 Technical Information
Power Derating Function
Power Derating Function
An enhanced power derating is implemented to provide the following
benefits:
Immediate auto-detection of changing requirements in the
application.
Dynamic TMP performance adapting to application conditions for
customer’s process stabilization and speeding-up.
Always the best “tuning” for TMP pumping technology taking the
complete advantage of TwisTorr technology potential.
Pump components minimized stress by mean of continuous TMP
parameters tuning for extended reliability.
The enhanced power derating dynamically adapts per the following
functioning parameters:
Gas type load (selectable WIN 157: see the following "Window
Meanings" paragraph).
Cooling mode (selectable WIN 106: see the following "Window
Meanings" paragraph).
Actual
Pump
temperature (can be read by WIN 2
04
).
Actual Driving Frequency (can be read by WIN 203).
Refer to the PUMP manual for further description.
WARNING!
The user must set the gas type load (WIN 157) and Cooling mode (WIN 106) before
starting the pump.
The applied power limit is readable by serial line (WIN 155).
If the pump body temperature exceed 55 °C or the pump bearing
temperature exceed 60 °C or the Controller temperature exceed
60 °C, the controller goes in status 6 (Fail).
