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 first point along the characteristic.
Dependency: Selects the freely programmable characteristic using p1300 = 3.
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Refer to: p1310, p1311, p1320, p1322, p1323, p1324, p1325, p1326, p1327
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: The programmable characteristic for the U/f control is defined using 4 points and 0 Hz/p1310.
This parameter specifies the voltage of the second point along the characteristic.
Dependency: The following applies to the frequency values: p1320 <= p1322 <= p1324 <= p1326. Otherwise, a standard
characteristic is used that contains the rated motor operating point.
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Refer to: p1310, p1311, p1320, p1321, p1323, p1324, p1325, p1326, p1327
