Time
Only with linear characteristic curve (P211 = 0% and P212 = 0%).
Time limit for suppression of pulse switch-off (P537): enables start-up under heavy load.

Oscillation damping
P217
(Oscillation damping)
0 ... 400 % With the oscillation damping, idling current harmonics can be damped. Parameter 217 is a measure
of the damping power.
{ 10 }
For oscillation damping the oscillation component is filtered out of the torque current by means of a
high pass filter. This is amplified by P217, inverted and switched to the output frequency.
The limit for the value switched is also proportional to P217. The time constant for the high pass
filter depends on P213. For higher values of P213 the time constant is lower.
With a set value of 10 % for P217, a maximum of ± 0.045 Hz are switched in. At 400 % in P217,
this corresponds to ± 1.8 Hz
The function is not active in "Servo mode, P300".

Modulation depth
P218
(Modulation depth)
50 ... 110 % This setting influences the maximum possible output voltage of the FI in relation to the mains
voltage. Values <100% reduce the voltage to values below that of the mains voltage if this is
{ 100 }e
required for motors. Values >100% increase the output voltage to the motor increased the
harmonics in the current, which may cause swinging in some motors.
Normally, 100% should be set.
