1.1.17 What does the operating mode S6 mean for circular saw motors?

1-SEVA-Kreiss-gemotor-230V-Drehrichtung-Rechts

Operating mode S6, duty cycle ED=40%, cycle time 10mins. The motor may run for 4 minutes under load and must then cool down for 6 minutes at no load, otherwise overheating is likely to occur. A short-term operation can be converted into continuous operation.

 

Here is a corresponding overview of the nominal operating modes:
