129.11 Current sampling time offset
This parameter determines the starting time of the current measurement. For current con-
trol, the fundamental of the motor currents should be measured if possible. The harmon-
ics, which result from, among other things, the switching edges of the PWM, can distort
the measurement. The parameter can be used to take account of time-related influences
such as, e.g., the time constant of the analog current filter.
129.12 Nominal current 2 kHz
129.13 Nominal current 4 kHz
129.14 Nominal current 8 kHz
129.15 Nominal current 16 kHz
Nominal current of converter at the corresponding PWM switching frequency Z130.15–.
The value in this parameter applies to the required operating conditions. See chapter
"Technical data" of the device's operating manual.
The instantaneous nominal current of the power unit dependent of the PWM frequency
entry
Z130.15– is displayed in parameter Z6.25–.
If operating conditions are changed and after current derating, the continuous current is
displayed in parameter
Z175.7– provided that the PU-overload monitoring is executed
via temperature model. See "Status PU temperature model" Z175.2–.
