Parameter Descriptions
14-55 Output Filter
Option:
[2] Sine- This parameter sets a minimum allowed limit to the
Wave switching frequency and ensures that the filter is
Filter operated within the safe range of switching

Fixed frequencies. Operation is possible with all control
principles. For Flux control principle
parameter 14-56 Capacitance Output Filter and
parameter 14-57 Inductance Output Filter have to be
programmed (these parameters have no effect in
VVC
SFAVM, which gives the lowest acoustic noise in the
filter.
NOTICE
Reset the frequency converter after selecting
[2] Sine-Wave Filter Fixed.
Always set parameter 14-55 Output Filter to
[2] Sine-wave fixed when using a sine-wave
filter. Failure to do so can result in
overheating of the frequency converter,
which can result in personal injury and
equipment damage.
14-56 Capacitance Output Filter
Compensation function of the LC filter requires the per phase
equivalent star-connected capacitance of the filter (3 times the
capacity between 2 phases when capacitance is 'Delta'
connection).
