When this mode is selected, the actual output phase sequence of the drive will be
contrary to the setting. For example, during terminal control, the function of the RUN key on
the keyboard will be reversed.

Note:
1. In order to obtain better control characteristics, it is suggested that the proportion of
carrier frequency to the highest operating frequency of drive should be no less than 36.
2. When the carrier frequency is low, the current display value has an error.

When the automatic adjustment selection of carrier frequency acts, the drive can
automatically adjust the carrier frequency according to the operating frequency. In this case,
the actual highest working carrier frequency of the drive is restricted by the carrier
frequency set by the function code (F1.25).
