These parameters display the temperature of various parts of the drive in degrees Celsius. The power stage is monitored at two points (Pr 7.04 and
Pr 7.05) and the control board is also monitored (Pr 7.06). The following trips and alarms can are produced from the values in these parameters.
Parameter
Pr 7.04
Stack temperature 1 (IGBT)
Pr 7.05
Stack temperature 2 (power PCB)
Pr 7.06
Control board temperature
The threshold levels for the stack temperature trips and alarm vary between drive sizes.
The values displayed in the parameter are normally between -20 and +127°C. If the value measured from the thermistor exceeds the range from -20
to +150°C it is assumed that the device is either open-circuit or short-circuit.
