deceleration, the drive outputs the frequency after the power is
restored): dEb is automatically cleared.
Hand
When Pr. 07-13=1 (dEb with auto-acceleration / auto-
deceleration, the drive does not output the frequency after the
power is restored): The drive stops when dEb acts and the
rotation speed becomes 0 Hz, then the drive can be reset
