Description: The programmable characteristic for the V/f control is defined using 4 points and 0 Hz/p1310.
This parameter specifies the frequency of the fourth point along the characteristic.
Dependency: Selects the freely programmable characteristic using p1300 = 3.
The following applies to the frequency values: p1320 <= p1322 <= p1324 <= p1326. Otherwise, a standard charac-
teristic is used that contains the rated motor operating point.
Refer to: p1310, p1311, p1320, p1321, p1322, p1323, p1324, p1325, p1327
Note: Linear interpolation is carried out between the points 0 Hz/p1310, p1320/p1321 ... p1326/p1327. For output fre-
quencies above p1326, the characteristic is extrapolated with the gradient between the characteristic points
p1324/p1325 and p1326/p1327.
The voltage boost when accelerating (p1311) is also applied to the freely programmable V/f characteristic.
Description: The programmable characteristic for the V/f control is defined using 4 points and 0 Hz/p1310.
This parameter specifies the voltage of the fourth point along the characteristic.
Dependency: Selects the freely programmable characteristic using p1300 = 3.
Refer to: p1310, p1311, p1320, p1321, p1322, p1323, p1324, p1325, p1326
Note: Linear interpolation is carried out between the points 0 Hz/p1310, p1320/p1321 ... p1326/p1327.
The voltage boost when accelerating (p1311) is also applied to the freely programmable V/f characteristic.
Description: Sets the signal source for the voltage setpoint for V/f control with an independent voltage setpoint (p1300 = 19).
Dependency: Selects the V/f control with independent voltage setpoint via p1300 = 19.
Refer to: p1300
Description: Sets the starting frequency at which FCC (Flux Current Control) is activated.
Dependency: The correct operating mode must be set (p1300 = 1, 6).
Warning: An excessively low value can result in instability.
Note: For p1333 = 0 Hz, the FCC starting frequency is automatically set to 6 % of the rated motor frequency.
