An OPE05 fault (unknown fault code on the touchscreen) is a command misalignment fault code. The VFD has detected a conflict in the commands it is receiving, such as receiving a forward and reverse command at the same time. The possible causes and solutions are shown below.
1. There is a parameter conflict. Contact MacroAir Technical Support to confirm the VFD programming.
2. If an analog remote is being used, confirm that the wiring on the remote and on the VFD are correct per our installation manual found here.
3. If everything appears to be installed and programmed correctly, contact MacroAir Technical Support.
