I've installed a Hitachi WJ200 VFD on my Sharpe knee mill with a single poly-v belt replacing the worn out variable drive parts.
I believe I have all the parameters set correctly. I even installed a braking resistor to allow quick spin down.
The small issue I am having is getting the WJ200 to default to display d007 (scaled output frequency) instead of what appears to be the default d001 (output frequency monitor) function.
I have parameter b086 (frequency scaling conversion factor) set correctly so that d007 accurately displays the spindle rpm (I checked it with a hand-held laser tachometer).
The manual states: If the inverter display is set to monitor a parameter and powerdown occurs, the inverter stores the present monitor function setting. For your convenience, the display automatically returns to the previously monitored parameter upon the next powerup.
The problem is this doesn't work. Every time I power up the VFD, it defaults to display d001.
I'll contact Hitachi next week, but I thought I'd see if anyone here might help.
