List of parameters
p1341[0...n] I_max frequency controller integral time / I_max_ctrl Tn
Access level: 3
Can be changed: U, T
Units group: -
Min
0.000 [s]
Description: Sets the integral time for the I_max frequency controller.
Dependency: Refer to: p1340
Note: When p1341 = 0, the current limiting controller influencing the frequency is de-activated and only the current limiting
controller influencing the output voltage remains active (p1345, p1346).
In the case of power units with regenerative feedback (PM250, PM260), current limitation control for a regenerative
load is always implemented by influencing the frequency. This current limiting function is de-activated with p1340 =
p1341 = 0.
r1343 CO: I_max controller frequency output / I_max_ctrl f_outp
Access level: 3
Can be changed: -
Units group: 3_1
Min
- [rpm]
Description: Displays the effective frequency limit.
Dependency: Refer to: p1340
r1344 I_max controller voltage output / I_max_ctrl U_outp
Access level: 3
Can be changed: -
Units group: 5_1
Min
- [Vrms]
Description: Displays the amount by which the converter output voltage is reduced.
Dependency: Refer to: p1340
p1345[0...n] I_max voltage controller proportional gain / I_max_U_ctrl Kp
Access level: 3
Can be changed: U, T
Units group: -
Min
0.000
Description: Sets the proportional gain for the I_max voltage controller.
Dependency: Refer to: p1340
Note: The controller settings are also used in the current controller of the DC braking (refer to p1232).
p1346[0...n] I_max voltage controller integral time / I_max_U_ctrl Tn
Access level: 3
Can be changed: U, T
Units group: -
Min
0.000 [s]
Description: Sets the integral time for the I_max voltage controller.
Dependency: Refer to: p1340
