Notice: When de-activating the I_max controller, the following must be carefully observed:
When the maximum current (r0067) is exceeded, the output current is no longer reduced, however, overcurrent
alarm messages are generated. The drive is shut down if the overcurrent limit (r0209) is exceeded.
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).
