5.6.2.4
Current derating as a function of the pulse frequency
When the pulse frequency is increased, the derating factor of the output current must be
taken into account. This derating factor must be applied to the currents specified beforehand
in the technical data.
Table 5- 15
Table 5- 16
Note
For pulse frequencies in the range between the specified fixed values, the relevant derating
factors can be determined by linear interpolation.
