Only advisable with linear characteristic curve (P211 = 0% and P212 = 0%).
For drives that require a high starting torque, this parameter provides an option for switching in an
additional current during the start phase. The application time is limited and can be selected at
parameter >Time boost precontrol< P216.
All current and torque current limits that may have been set (P112 and P536, P537) are deactivated
during the boost lead time.
NOTE:
With active ISD control (P211 and / or P212 ≠ 0%), parameterisation of P215 ≠ 0 results in incorrect
control.

Time limit for the boost lead: Application time for increased starting current.
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
(Oscillation damping)

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 ± 0.045 Hz are switched in. At 400 % in P217,
this corresponds to ± 1.8 Hz
The function is not active in “Servo mode, P300”.

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
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.
