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

6.6 Protection functions
After selecting an
induction motor
(p0300) or a listed
induction motor
(p0301) during the
commissioning,
the inverter sets
the parameters to
values appropriate
for the motor.
The parameters
are write-
protected for listed
motors
(p0301 ≥ 0).
