P216 (P)
Time boost precontrol
always visible
0.0 ... 10.0 s
[ 0 ]
Only with linear characteristic curve (P211 = 0% and P212 = 0%).
Application time for increased starting current.
P217
Oscillation damping
always visible
10 ... 400 %
[ 10 ]
With the oscillation damping, idling current harmonics can be damped. Parameter 217 is a measure of
the damping power.
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 ± 0.045Hz are switched in. At 400% in P217, this
corresponds to ± 1.8Hz
The function is not active in “Servo mode, P300”.
P218
Modulation depth
always visible
50 ... 110 %
[ 100 ]
The modulation depth can be changed between 50% and 110%. Values under 100% limit the voltage
at the motor to smaller values than the mains voltage. This is not feasible for typical applications with
three-phase asynchronous motors.
Values greater than 100% increase the voltage available at the output, but also the current harmonics,
which can lead to oscillation in some motors.
