Information
V/f characteristic curve
With certain applications, particularly those with high centrifugal mass (e.g. fan drives), it may be
necessary to control the motor with the aid of a U/f characteristic curve. In order to do this, set
parameters
P211
and
P212
each to 0%.

Information
PMSM
When controlling a PMSM, this parameter determines the voltage of the test signal method
(
P330
). The required voltage depends on various factors (ambient and motor temperature, motor
size, motor cable length, size of variable frequency drive). If the rotor position identification is not
successful, this parameter can be used to adjust the voltage.

ISD ctrl. loop gain
(amplification ISD control)
S
P
25 ... 400 %
{ 100 }
This parameter affects the control dynamics of the VFD current vector control (ISD control). Higher
settings make the controller faster, lower settings slower.
Depending on the type of application, this parameter can be adjusted to avoid unstable operation
for example.

P214
Torque precontrol
(torque derivative action)
S
P
-200 ... 200 %
{ 0 }
This function allows a value for the expected torque requirement to be set in the current controller.
This function can be used in lifting gears for better load transfer during startup.
NOTE:
In clockwise rotary field direction, motor torques are entered with a positive sign, while
regenerative torques are entered with a negative sign. The reverse applies to
counterclockwise rotation.

Boost precontrol
(boost derivative action)
S
P
0 ... 200 %
{ 0 }
Only advisable in linear characteristic curves (P211 = 0% and P212 = 0%).
For drives that require a high starting torque, this parameter provides an option for adding an
additional current during the start phase. The operative time is limited and can be selected in
parameter P216 >Boost derivative action time<.
All current and torque current limits that may have been set (P112, P536, P537) are deactivated
during the boost derivative action time.
NOTE:
With active ISD c
ontrol (P211 and/or P212 ≠ 0%), parameterization of P215 ≠ 0 results in incorrect
control.
