What do you mean by "S1-100" on the wiring board?
S5 includes electric brake of duty cycle: according to a series of work in the same period, each cycle comprises a starting time, a constant load running time, a fast electric braking time and a stopping.
S4 includes starting duty cycle: according to a series of work in the same period, each cycle comprises a section on temperature has significant effect on the starting time, a constant load running time and a stopping.
S3 intermittent duty cycle operates in a series of identical operating cycles, each cycle including a constant load, running time, and a period of breaking and stopping. The starting current in each cycle of this system does not have a significant effect on the temperature rise.
S2 short work: according to the given time running under constant load, the lack of time to reach thermal stability, then stopped enough time to make the motor again cool down to ambient temperature difference within 2K.
This is the work of electrical system, S1-100% motor is allowed to run for a long time; the motor system is divided into ten grades: S1~S10; S1: continuous working system running time under constant load to achieve thermal stability.
