2.2 List of parameters
Note: The I_max limiting controller becomes ineffective if the ramp-function generator is de-activated with p1122 = 1.
p1341 = 0: I_max frequency controller de-activated and I_max voltage controller activated over the complete speed
range.
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.
Description: Displays the effective frequency limit.
Dependency: Refer to: p1340
Description: Displays the amount by which the converter output voltage is reduced.
Dependency: Refer to: p1340
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).
Description: Sets the integral time for the I_max voltage controller.
Dependency: Refer to: p1340
