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.

inverter
l General rule: The lower the
switching frequency the
– lower the power loss
– higher the noise generation
– better the concentricity
factor

for high switching frequencies
