Description: p1312 causes an additional voltage boost when starting, however, only for the first acceleration phase.
The voltage boost becomes effective for a positive setpoint increase and disappears as soon as the setpoint has
been reached. The build-up and withdrawal of the voltage boost are smoothed.
Dependency: The current limit p0640 limits the boost.
Refer to: p1300, p1310, p1311, r1315
Notice: The voltage boost results in a higher motor temperature increase.
Note: The voltage boost when accelerating can improve the response to small, positive setpoint changes.
Assigning priorities for the voltage boosts: refer to p1310
Description: Displays the total resulting voltage boost in volt (p1310 + p1311 + p1312).
Dependency: Refer to: p1310, p1311, p1312
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 first 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: p1300, p1310, p1311, p1321, 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 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 first point along the characteristic.
Dependency: Selects the freely programmable characteristic using p1300 = 3.
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 V/f characteristic.
