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: p1311 only results in a voltage boost when accelerating and generates a supplementary torque to accelerate the
load.
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.
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 field orientation (p1302 bit 4 = 1, not PM230, PM250, PM260), p1311 is pre-assigned by the automatic
calculation.
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
For field orientation (p1302 bit 4 = 1, not PM230, PM250, PM260), then p1311 together with p1310 and p1302.5 are
mainly responsible for the quality of the drive response.
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.
