Current derating
The BL 4100-M / BL 4100-D series servo drives have a current derating during nominal
operation. The rated current and the duration of the maximum permissible peak current of
the servo drive depend on several factors. These factors are:
l
Output current level: The higher the output current is, the shorter the permissible
time will be.
l
Clock frequency of the power output stage: The higher the clock frequency is, the
shorter the permissible time will be.
The current derating begins as of a PWM frequency of 10 kHz (f
PWM
) and is linear
between the reference values that are stated in the following table:

The PWM frequency is the reciprocal of half of the current controller cycle time t
i
. The
variable cycle times enable particularly high dynamics combined with reduced power
data.
