Goodrive3000 series medium voltage inverters
After the motor finishes the parameter autotuning normally, the set values of P02.06~P02.10 will
automatically update. These parameters are the fundamental parameters of high performance vector
control and directly influence control performance.

protection
0: No protection
1: Common motor (with low speed compensation): because the heat dissipation effect of the common
motor at low speed will be weakened, the corresponding electric heat protection will be adjusted properly.
The low speed compensation characteristic mentioned here means reducing the threshold of the
overload protection of the motor whose running frequency is below 30Hz.
2: Frequency conversion motor (without low speed compensation): because the heat dissipation effect of
the special motor for the inverter is not affected by the speed, there is no need to adjust the protection
value during low speed running.
