Drive for a synchronous/asynchronous motor working as a spindle
The following graphs show the maximum rms current in continuous S1
and intermittent S6-40 ( IS6-40 ) duty cycles depending on the switching
frequency of the power transistors in a temperature range between
5°C/41°F and 60°C/140°F. See the load duty cycles.
 For a switching frequency fc = 4 kHz
