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.

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.
