Description: The programmable characteristic for the U/f control is defined using 4 points and 0 Hz/p1310.
This parameter specifies the voltage of the third point along the characteristic.
Dependency: Refer to: p1310, p1311, p1320, p1321, p1322, p1323, p1324, p1326, p1327
Description: The programmable characteristic for the U/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 for the frequency values:
p1320 <= p1322 <= p1324 <= p1326
Otherwise, a standard characteristic 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 U/f characteristic.
Description: The programmable characteristic for the U/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 U/f characteristic.
Description: Sets the signal source for the voltage setpoint for U/f control with an independent voltage setpoint (p1300 = 19).
Dependency: Selects the U/f control with independent voltage setpoint via p1300 = 19.
Refer to: p1300
