210 Actual signals and parameters
ON (LOAD) Switching frequency can adapt to loading instead of limiting
the output current. This allows maximum loading with all
switching frequency selections. The drive automatically
decreases the actual switching frequency if loading is too
high for the selected switching frequency.

2608 SLIP COMP
RATIO
Defines the slip gain for the motor slip compensation
control. 100% means full slip compensation, 0% means no
slip compensation. Other values can be used if a static
speed error is detected despite the full slip compensation.
Example: 35 Hz constant speed reference is given to the
drive. Despite the full slip compensation (SLIP COMP
RATIO = 100%), a manual tachometer measurement from
the motor axis gives a speed value of 34 Hz. The static
speed error is 35 Hz - 34 Hz = 1 Hz. To compensate the
error, the slip gain should be increased.

0…200% Slip gain 1 = 1%
2609 NOISE
SMOOTHING
Enables the noise smoothing function. Noise smoothing
distributes the acoustic motor noise over a range of
frequencies instead of a single tonal frequency resulting in
lower peak noise intensity. A random component with an
average of 0 Hz is added to the switching frequency set by
parameter 2606 SWITCHING FREQ.
Note: Parameter has no effect if parameter 2606
SWITCHING FREQ is set to 16 kHz.
