206 List Manual (LH11), 01/2016, A5E33839529
Description: Sets the signal source for the voltage setpoint for U/f control with an independent voltage setpoint (p1300 = 19).
Dependency: Selects the U/f control with independent voltage setpoint via p1300 = 19.
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Refer to: p1300
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.
Dependency: Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
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).
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
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.
Dependency: Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Note: For p1334 = 0, the starting frequency of the slip compensation is automatically set to 6 % of the rated motor
frequency.
p1330[0...n] CI: U/f control independent voltage setpoint / Uf U_set independ.
