2.2 List of parameters
The magnitude of the boost in Volt at a frequency of zero is defined as follows (not for field orientation):
Voltage boost [V] = 1.732 * p0305 (rated motor current [A]) x r0395 (stator/primary section resistance [ohm]) x p1311
(voltage boost when accelerating [%]) / 100 %
Dependency:
The current limit p0640 limits the boost.
For vector control, the starting current is realized using p1611.
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Refer to: p1300, p1310, p1312, 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:
Setting for an additional voltage boost when powering-up, 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.
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
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
For field orientation (p1302.4 = 1, not PM230, PM250, PM260), p1312 of the voltage boost is also added in the
direction of the load current (non-linear).
Description:
Displays the total resulting voltage boost in volt.
For field orientation (p1302.4 = 1, not for PM230, PM250, PM260), at low speeds, as a minimum the magnetizing
current is set, so that the voltage depends on r0331.
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Refer to: p1310, p1311, p1312
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.
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: p1300, p1310, p1311, p1321, p1322, p1323, p1324, p1325, p1326, p1327
