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 are also added in the
direction of the load current (non-linear).
Description: Displays the total resulting voltage boost in volt.
r1315 = p1310 + p1311 + p1312
For field orientation (p1302.4 = 1, not for PM230, PM250, PM260):
r1315 = p1310
Dependency: Refer to: p1310, p1311, p1312
Description: Limiting the voltage setpoint.
This means that the output voltage can be reduced with respect to the calculated maximum voltage r0071 and the
start of field weakening.
Note: The output voltage is only limited if, as a result of p1331, the maximum output voltage (r0071) is fallen below.
Description: Sets the starting frequency at which FCC (Flux Current Control) is activated.
Dependency: The correct operating mode must be set (p1300 = 1, 6).
Warning: An excessively low value can result in instability.
Note: For p1333 = 0 Hz, the FCC starting frequency is automatically set to 6 % of the rated motor frequency.
Description: Sets the starting frequency of the slip compensation.
Note: For p1334 = 0, the starting frequency of the slip compensation is automatically set to 6 % of the rated motor
frequency.
