Current derating on ·ACD|CMC 2.50· drives for fc = 8 kHz.
Drive for a synchronous|asynchronous motor working as a spindle
The following graphs show the maximum rms current in continuous duty
cycle (that is, the rated one) depending on the switching frequency of the
power transistors that the drives for asynchronous motors can supply in a
temperature range between 5°C/41°F and 60°C/140°F.
 For a switching frequency fc = 4 kHz
