Hi folks:
I'm new to the reflector, so my apologies if this is an oft-repeated question.
My PM-935TS mill showed up this month, and I'm learning a bit about adding a VFD to this.
I expect to use the Hitachi WJ200-022sf.
I need an enclosure (with adequate space as per the VFD's manual), correct?
Should I use the existing REV/STOP/FOR switch on the mill, and add to this a speed potentiometer?
(such as a 10K one turn pot kit)?
Or should the existing switch be replaced with a new unit, say an FMX unit at one of the on-line distributors with an
EMER STOP/ FOR-REV / 10K pot in one box?
Should I consider a adding a resistor for braking? I'm not doing particularly heavy work, but is this a convenience to consider?
I do operate radio equipment (ham radio op) in this building. Should I consider adding an RF noise filter, such as Hitachi's ZCL-B40?
This looks like an iron core winding that wires simply go around a few times. Input or output of VFD, or both?
Its about 2.5 yards to the breaker box. Do I need shielded cables or anything like that?
Any suggestions are welcome! Or point me elsewhere where these questions have already been addressed!
I'm going to have an electrician do the work. I just want to make sure I have all of the pieces on hand!
Thanks,
Ted
