Dimensioning notes:
● A current derating is only applicable for output frequencies < 10 Hz.
● Current derating should be taken into account if the percentage time of operation at
frequencies < 10 Hz is more than 2 % of the daily total operating time.
● Also during load cycles, the current specified here must not be exceeded.
● When quickly passing through frequencies 0 to 10 Hz, derating does not have to be taken
into account (e.g. for positioning applications).
Note
Information about derating the output current as a function of the ambient temperature and
installation altitude is provided in Chapter "System data (Page 46)".
