The User Manual of 580 Series General Frequency Converter

4.8.9 Setting the operation direction of motor

After the frequency converter restores the delivery parameter, press RUN key, the frequency converter will drive the motor for running, called forward direction. If rotating direction is opposite to the running direction as required by the equipment, please power off, change any two of UVW output lines of frequency converter and solve the problem in rotating direction. If there is the field in which forward running and reverse running are required in some driving systems, the “reverse control prohibition” shall be set to the state in which reverse running is allowed, namely, function code F8-13=0. In addition, the “running direction” shall be set to reverse running, namely, F0-09=1. Press RUN key so that the motor will be rotated in reverse direction, as shown in the following logic in the figure:

Fig. 4-25 Setting the running direction of motor

When the terminal run command is used for control, if reverse running is needed, the function code F8-13=0 shall be essential and the reverse control function is allowed. Seen from the figure above, if the reverse running (F8-13=0) is allowed and the operation frequency of frequency converter (F0-03=9) is given in communication mode, when the given frequency Fs is negative, the frequency converter will be in reverse running; when the reverse running command is given externally or the given frequency is negative, but the frequency converter is set to the state in which the reverse running is not forbidden (F8-13=1), the frequency converter will be operated with 0Hz and there is no output. For the application in which the reverse running of motor is not allowed, please never change the rotating direction by the change of function code because the said two function codes will be reset after the default value is restored.
