In case of the first selection enter
the motor data and identify them
with C0148.

C0010 is only
effective in case
of analog setpoint
selection via AIN1

Important: For
parameter setting
via interface, major
changes in one step
should only be made
when the controller
is inhibited.

General rule: the lower the
switching frequency the
– lower the power loss
– higher the noise generation
– better the concentricity

factor
