Note
Free convection must be possible for operation without water cooling.
Load duty cycles with varying on period
As well as continuous duty (S1), standard intermittent duty types (S3) are also defined for
load duty cycles with varying on periods. This involves operation that comprises a sequence
of similar load cycles, each of which comprises a time with constant load and an off period.
Figure 5-3 S1 duty (continuous operation)
Figure 5-4 S3 duty (intermittent operation without influencing starting)
The load torque must lie below the corresponding thermal limiting characteristic of the motor.
An overload must be taken into consideration for load duty cycles with varying on times.
Note
For duty cycles in the field weakening range, the SIZE
R for SIEMENS Drives engineering
tool must be used. The following form
ulas can be used for duty cycles outside the field
