P-0-0090 Channel peak current

The channel peak current is a hardware related limit, which means that the peak torque is also limited.

All currents are controller specific. They consist of the PWM frequency (P-0-0001) and the max. parameterized supply voltage Umain_max together. The mains voltage Umain_max calculated from the parameters P-0-0201 (nominal mains voltage) and P-0-0202 (Mains voltage positive tolerance range).

The controller can be operated on a network and maybe the mains voltage is for example 400V ± 10% / 480V ± 10%. Exactly these requirements are parameterized. At a higher voltage, the peak current, nominal current may be smaller!

The settings refer to a switching frequenzy of 8 kHz.
