NOTICE
When deactivating the I_max controller, the following must be carefully observed:
When the maximum current (r0067) is exceeded, the output current is no longer reduced. The drive is switched off
when the overcurrent limits are exceeded.
Note
The I_max limiting controller becomes ineffective if the ramp-function generator is deactivated with p1122 = 1.
p1341 = 0:
I_max frequency controller deactivated and I_max voltage controller activated over the complete speed range.
p1341[0...n]
I_max frequency controller integral time / I_max_ctrl Tn
Access level: 3
Can be changed: T, U
Unit group: -
Min:
0.000 [s]
Description:
Sets the integral time for the I_max frequency controller.
Dependency:
See also: p1340
Note
When p1341 = 0, the current limiting controller influencing the frequency is deactivated 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 deactivated with p1340 =
p1341 = 0.
r1343
CO: I_max controller frequency output / I_max_ctrl f_outp
Access level: 3
Can be changed: -
Unit group: 3_1
Min:
- [rpm]
Description:
Displays the effective frequency limit.
Dependency:
See also: p1340
r1344
I_max controller voltage output / I_max_ctrl U_outp
Access level: 3
Can be changed: -
Unit group: 5_1
Min:
- [Vrms]
Description:
Displays the amount by which the converter output voltage is reduced.
Dependency:
See also: p1340
p1345[0...n]
I_max voltage controller proportional gain / I_max_U_ctrl Kp
Access level: 3
Can be changed: T, U
Unit group: -
Min:
0.000
Description:
Sets the proportional gain for the I_max voltage controller.
