I bought a used 3HP WJ200 and I'm hoping I didn't get a dud. I set up the motor parameters and it seems to be functioning OK, but it's stuck on 5Hz. I think parameter A001 is what selects what controls the speed, but I can't get it to change to the arrow keys on the VFD. I really need to hard reset it but I can't get that to work either. It never displays D001 like it's suppose to. Is there something I'm overlooking? Below is the procedure for resetting a WJ200 listed on Hitachi's website.
How do I restore factory default in WJ200 series inverters?
Answer:
Please navigate to parameter B084 and use the "Set" button to change to 02. Then navigate and change B180 to 01 and press "Set". The display will change to d001, indicating the reset is complete.
