14-55 Output Filter
Option: Function:
frequencies. Operation is possible with all control
principles. For FLUX control principle the parameters
14-56 Capacitance Output Filter and 14-57 Inductance
Output Filter have to be programmed (these
parameters have no effect in VVC
modulation pattern is set to SFAVM which gives the
lowest acoustic noise in the filter.
Note:
Reset the frequency converter after selecting [2]
Sine-Wafe Filter Fixed.
CAUTION
Always set 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).
Range: Function:
Size related [0.1 - Set the capacitance of the output filter.

14-57 Inductance Output Filter
Range: Function:
Size related [0.001 - Set the inductance of the output filter.
*
65 mH] The value can be found on the filter
label.
NOTICE
This is required for correct
