Drive for a synchronous/asynchronous motor working as a spindle
The following graphs show the maximum rms current in continuous S1 (ln)
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
F. H3/25
Current derating on ·SPD 1.15· drives for fc = 4 kHz.
F. H3/26
Current derating on ·SPD 1.25· drives for fc = 4 kHz.
F. H3/27
Current derating on ·SPD 1.35· drives for fc = 4 kHz.
F. H3/28
Current derating on ·SPD 2.50· drives for fc = 4 kHz.
