dEb function selection
0: Disable
1: dEb with auto-acceleration / auto-deceleration, the drive does not
output the frequency after the power is restored.
2: dEb with auto-acceleration / auto-deceleration, the drive outputs the
frequency after the power is restored.
3: dEb low-voltage control, then the drive’s voltage increases to 350
Vdc/700 Vdc and ramps to stop after low frequency
4: dEb high-voltage control of 350 Vdc / 700 Vdc, and the drive ramps to
stop
