The inverter sets bit 09 = 1 after commissioning. If you
load the parameter settings for firmware version ≤ V4.6
into the inverter, bit 09 = 0 remains.

Advanced commissioning
After selecting an induc‐
tion motor (p0300) or a
listed induction motor
(p0301) during the com‐
missioning, the inverter
sets the parameters to
values appropriate for
the motor.
The parameters are
write-protected for listed
motors (p0301 ≥ 0).
