With the permissible continuous DC link power, the power supply current, e.g. with a
power supply voltage of 480 V
AC
, is less by a ratio

).
When selecting the connected axes ensure that the DC link power is not exceeded.

Axis units
BM53XX
The axis units supply the rated/peak currents at rated DC link voltage. The output currents
must be reduced accordingly when operating with a DC link voltage is higher than 640 V
and output power remains constant.
