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

Operating mode S6 , duty cycle ED=40%, operating time 10 min. The motor may run under load for 4 minutes and must then cool down for 6 minutes at idle, otherwise overheating would occur. Short-term operation can be converted into continuous operation.

Here is a corresponding overview of the nominal operating modes:

Abbreviation	Description	required additional information
S1	Continuous operation with constant load
S2	Short-term operation	Load duration
S3	Periodic intermittent operation	Relative ED in % (based on 10 min)
S4	Periodic intermittent operation with the influence of the start-up process	rel. ED in % Switching cycles per hour moment of inertia Ramp -up and shutdown time
S5	Periodic intermittent operation with the influence of the start-up process and electric braking	rel. ED in % Switching cycles per hour moment of inertia Ramp-up and ramp-up time
S6	Continuous periodic operation	Relative ED in % (based on 10 min)
S7	Continuous periodic operation with electric braking	Switching cycles per hour moment of inertia Ramp-up and ramp-up time
S8	Continuous periodic operation with load and speed changes	Switching cycles per hour moment of inertia Ramp-up and ramp-up time
S9	Operation with non-periodic load and speed changes	Switching cycles per hour moment of inertia Ramp-up and ramp-up time
S10	Operation with individual constant loads
