15.3 PROTECTIONS [45]
The parameters related to motor and inverter protections are found in this group.
P0030 – U Arm IGBT Temperature
P0031 – V Arm IGBT Temperature
P0032 – W Arm IGBT Temperature
P0033 – Rectifier Temperature
P0034 – Internal Air Temperature
Adjustable
Range: -20.0 to 150.0 °C Factory

Description:
These parameters present, in Celsius degrees, the heatsink temperature on the U, V and W arms (P0030, P0031
and P0032), of the rectifier (P0033), and also of the internal air (P0034).
They are useful to monitor the temperature on the main inverter sections in case of an occasional inverter
overheating.
P0156 – Motor Overload Current at 100 % of its Rated Speed
P0157 – Motor Overload Current at 50 % of its Rated Speed
P0158 – Motor Overload Current at 5 % of its Rated Speed
Adjustable
