Extended error message S300 / S700
a second error message with a small "i" (ERRCODE2) is displayed in the display, which has the following meaning:

i 5 commutation fault: velocity control
i 6 commutation fault: current control
i 7 commutation fault: wrong segment of the Hall feedback
i 8 commutation fault: W&S contouring error
i 9 commutation fault: amplitude of W&S to high
i 10 commutation fault: amplitude of W&S to small
i 11 commutation fault: W&S IQ to high
i 12 commutation fault: W&S wrong average
i 20 Sine/Cosine amplitude is too large
