Sine filter

A sinusoidal filter in the motor cable limits the rate of voltage rise and the capacitive charge/
discharge currents between the conductors that occur during inverter operation.
Only use a sinusoidal filter with standard asynchronous motors 0 to 550 V.
Operation only with V/f or square-law V/f characteristic control.
Set the switching frequency permanently to the specified value.
Limit the output frequency of the inverter to the given value.

Power supply units
For the external supply of the control electronics of the inverter.
The parameterisation and diagnostics can be executed when the mains input at the inverter is
deenergised.
