SP-55 Output Filter
Option: Function:
NOTICE
This parameter cannot be adjusted while the
motor is running.
NOTICE
Reset the frequency converter after selecting
[2] Sine-Wave Filter Fixed.
CAUTION
OVERHEATING OF FREQUENCY
CONVERTER
Always set parameter SP-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.
Select if a sine-wave output filter connected.
[0] No This is the default setting and should be used with
Filter dU/dt filters or high frequency common mode (HF-
*
CM) filters.

Wave enables operation with flux control principle when
Filter parameter SP-56 Capacitance Output Filter and
parameter SP-57 Inductance Output Filter are
programmed with the output filter capacitance and
inductance. It does not limit the range of the
switching frequency.
[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, program
parameter SP-56 Capacitance Output Filter and
parameter SP-57 Inductance Output Filter (these
parameters have no effect in Advanced Vector
Control and U/f). The modulation pattern is set to
SFAVM, which gives the lowest acoustic noise in the
filter.

3.9.6 SP-7# Additional ADD/DEC Settings
Parameters to configure the jerk compensations for S-
Ramps settings on Accel/Decel Ramps 1 through 4.
For each of four ramps (parameter groups F-0#, E-1#, H-0#,
SP-7#, SP-8# and SP-9#) configure the ramp parameters:
ramp type, ramping times (duration of acceleration and
deceleration) and level of jerk compensation for S ramps.
Start by setting the linear ramping times corresponding to
the figures.
If S-ramps are selected then set the level of non-linear jerk
compensation required. Set jerk compensation by defining
the proportion of ramp-up and ramp-down times where
acceleration and deceleration are variable (i.e. increasing or
decreasing). The S-ramp acceleration and deceleration
settings are defined as a percentage of the actual ramp
time.

Function:
Set the actual number of power units.
Function:
