Maximum output frequencies achieved by increasing the pulse frequency
By multiplying the rated pulse frequency with a multiple integer, the following output
frequencies can be achieved taking into account the derating factors:
Table 3-24
Due to the closed-loop control, the maximum output frequency is limited to 300 Hz.

Note: A factor kT > 1.0 is only to be taken into account in conjunction with the current de-
rating factor depending on the installation altitude.
