4.8.9 Setting the Motor Rotating Direction
After the AC drive restores the default settings, press
RUN
to drive the motor to rotate. In
this case, the rotating direction is regarded as the forward rotation. If the rotating direction is
reverse to the direction required by the equipment, power off the AC drive and exchange any
two of the output UVW cables (wait until the main capacitor of the AC drive is completely
discharged).
In some applications where both forward rotation and reverse rotation are required, enable
the reverse control (F8-13 = 0, default value) and meanwhile reverse the rotating direction
by setting F0-09 to 1. Then press
RUN
to make the motor rotate in the reverse direction,
as shown in the following figure.

If the command source is terminal control and reverse rotation is required, use the default
value 0 of F8-13 to enable reverse control.
According to the preceding figure, when the running frequency of the AC drive is set by
means of communication (F0-03 = 9) and reverse control is enabled (F8-13 = 0), the AC
drive instructs the reverse direction if the set frequency Fs is a negative value.
If the give running command is reverse rotation or the set frequency is a negative value, but
reverse control is disabled (F8-13 = 1), the AC drive will run at 0 Hz and has no output.
In some applications where reverse rotation is prohibited, do not change the rotating
direction by modifying the function codes because the function codes will be restored once
the AC drive restores the default settings.
4.8.10 Setting the F ixed Length Control Mode
The MD380 has the fixed length control function. The length pulses are sampled by the DI
allocated with function 27 (Length count input). The "Actual length" (FB-06) is obtained by
dividing the number of pulses sampled by the value of FB-07 (Number of pulses per meter).
If the actual length is larger than the "Set length" (FB-05), the multifunctional DO terminal
becomes ON.
In the process of fixed length control, the length can be reset by means of the DI terminal
allocated with function 28 (Length reset). The related setting is shown in the following figure.
