4.4.1 Current derating
The ARS 2100 SE series servo drives have a current derating during nominal operation. The rated
current and the time of the maximum allowed peak current of the servo drive depend on different
factors.
These factors are:
Output current level (the higher the output current, the shorter the allowed time)
Power stage clock frequency (the higher the clock frequency, the shorter the allowed time)
Electrical rotational frequency of the motor (speed multiplied by pole pair number; the higher the
rotational frequency, the longer the allowed time)
The last point (electrical rotational frequency) only applies to the ARS 2108 SE. For a better clarity, we
only distinguish between electrical rotational frequencies less than 2 Hz and those over 3 Hz. For
rotational frequencies lying in between these two values, interpolation is required.
