2.2 List of parameters
p1331[0...n] Voltage limiting / U_lim
Access level: 3
Can be changed: U, T
Unit group: 5_1
Min
50.00 [Vrms]
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.
p1333[0...n] U/f control FCC starting frequency / U/f FCC f_start
Access level: 3
Can be changed: U, T
Unit group: -
Min
0.00 [Hz]
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.
p1334[0...n] U/f control slip compensation starting frequency / Slip comp start
Access level: 3
Can be changed: U, T
Unit group: -
Min
0.00 [Hz]
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.
p1335[0...n] Slip compensation scaling / Slip comp scal
Access level: 3
Can be changed: U, T
Unit group: -
Min
0.0 [%]
Description: Sets the setpoint for slip compensation in [%] referred to r0330 (motor rated slip).
p1335 = 0.0 %: Slip compensation de-activated.
p1335 = 100.0 %: The slip is completely compensated.
Dependency: Prerequisite for a precise slip compensation for p1335 = 100 % are the precise motor parameters (p0350 ... p0360).
If the parameters are not precisely known, a precise compensation can be achieved by varying p1335.
For U/f control types with Eco optimization (4 and 7), the slip compensation must be activated in order to guarantee
correct operation.
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
