Temperature control

Temperature measurements


The inverter measures several system temperatures for temperature control and other
diagnostic purposes. The amount of actual measurements depends on the number of
power sections in the inverter configuration.
Note: Currently, only power modules M1 and M2 are used.
The ambient temperature is measured from the main air channel intake and can be read in
parameter 211.01 Main air channel
The temperature of the control section cabinet is measured and read from parameter
211.05 Control board
The temperature of AC cabinet for each power section is measured and can be read with
parameters
211.09 AC cabinet M1 temperature
The temperature of LCL cabinet for each power section is measured and can be read with
parameters
211.13 LCL cabinet M1 temperature
The temperature of IGBT modules for each power section is measured. The highest IGBT
module temperature of each power section can be read with parameters
IGBT M1 temperature
The individual IGBT module temperatures of each power section can be read with
parameters:
•
211.25 M1 IGBT T1 temperature...211.33 M1 IGBT T9 temperature
•
211.34 M2 IGBT T1 temperature...211.42 M2 IGBT T9
The sensor fail status of individual temperature measurements can be read from status
parameters
211.71 Sensor fail
measurement sensor failure is detected. A temperature sensor fail warning is shown when
at least one temperature sensor failure is detected.
An overtemperature warning is shown when temperature(s) exceed the set warning levels.
An overtemperature fault is detected when temperature(s) exceed the set fault levels,
stopping the inverter operation. Note that these warning and fault levels are fixed and
cannot be edited.

Temperature based grid current limitation


The grid current can be limited due to a high ambient temperature or high internal inverter
temperatures. If the grid current is limited by the temperature based current limitation, a
status bit is set in the limitation status parameter
corresponding status bit is set in parameter
measurement that is the source of the limitation.
