Derating curves
Drive for an synchronous motor working as an axis
The following graphs show the maximum rms current in continuous S1 (l
N
)
and intermittent S3-5% (Imax.) 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. H3/7
Current derating on ·AXD|MMC 1.08· drives for fc = 4 kHz.
F. H3/8
Current derating on ·AXD|MMC 1.15· drives for fc = 4 kHz.
F. H3/9
Current derating on ·AXD|MMC 1.25· drives for fc = 4 kHz.
F. H3/10
Current derating on ·AXD|MMC 1.35· drives for fc = 4 kHz.
