MEANING
external fan configuration:
0 = Always On
1 = Serial (generic output serially controlled)
External fan setting
Vent valve opening time (expressed in 0.2sec; 0=infinite)
0 = molar mass ≥ 30 g/mol (e.g., Ar)
1 = 4 g/mol < molar mass < 30 g/mol (e.g., N2)
2 = molar mass ≤ 4 g/mol (e.g., H2, He)
It reads the pump speed while in stop mode
It reads the actual value of the bus current supplied by
controller to electric motor
It reads the actual value of the pk 3phase voltage supplied
by controller to electric motor
It reads the actual value of power supplied by controller to
electric motor
This is the actual exciting frequency
It reads the Body temperature
Real time pump status:
0 = Stop
1 = Interlock
2 = Ramp
3 = Autotuning
4 = Braking
5 = Normal
6 = Fail
This location has a bit significant:
11 = Run Up Time
10 = Body HW Over Temp
9 = RFU/Not used
8 = Rotor Locked
7 = Too Hight Load
6 = Fault DRV8305
5 = Vdc (supply) Over Voltage
4 = Thermalpad Overtemp
3 = Vdc (supply) Under Voltage
2 = Controller Over Temp
1 = Pump Over Temp
0 = No connection to pump
It reads the MOSFET bridge temperature
It reads the controller PCB temperature
Reports the actual state of setpoint output
