P1320[0...2] Programmable V/f freq.
coord. 1 [Hz]
0.00 -

0.00 T - DDS Float 3
Sets the frequency of the first point of V/f coordinates (P1320 / 1321 to P1324 / 1325) to define V/f
characteristic. These parameter pairs can be used to provide correct torque at correct frequency.
Dependency: To set parameter, select P1300 = 3 (V/f with programmable characteristic). The acceleration boost and
starting boost defined in P1311 and P1312 are applied to V/f with programmable characteristic.
Note: Linear interpolation will be applied between the individual data points.
V/f with programmable characteristic (P1300 = 3) has 3 programmable points and 2 non-programmable
points. The 2 non-programmable points are:
• Continuous boost P1310 at 0 Hz
• Rated motor voltage P0304 at rated motor frequency P0310

BICO parameter for selecting source of voltage setpoint for independent V/f control (P1300 = 19).
P1333[0...2] Start frequency for FCC
[%]
0.0 - 100.0 10.0 U, T PERCEN
T
DDS Float 3
Defines start frequency at which FCC (flux current control) is enabled as [%] of rated motor frequency
(P0310).
Notice: If this value is too low, the system may become unstable.
P1334[0...2] Slip compensation
activation range [%]
1.0 - 20.0 6.0 U, T PERCEN
T
DDS Float 3
To set the frequency activation range for slip compensation. The percentage value of P1334 refers to the
motor rated frequency P0310.
The upper threshold will always stay 4 % above P1334.
