Hitachi WJ200 JOG function programming help.

Hi Taki,

You can use an E-Stop in either wiring configuration (just two examples), it simply disconnects the VFD inputs. On some machines that come with an E-Stop, they usually interrupt 24VAC power to the contactors. As an added safety precaution I often use a separate switch block that interrupts the signaling to the VFD inputs. Just a safety thing, but depends on how everything is wired up. So in your case, suppose the jog switch failed closed, the E-Stop would still interrupt the VFD run signal. I set A039 = 4 (Controlled deceleration (valid during run)). Should not be anything else, you will need to program one of the inputs to the JOG function, usually input 3 "C003" and you would set it to 06JG:Jogging).

Thanks Mark! I'll let you know how I made out! Again, thanks for all the help!

Hey folks! I finally have all the pieces to start wiring. I’ve been slammed at work, then I decided I should do my boiler at home before it gets really cold...

I couldn’t find any shielded 12/3 for the motor leads, but I did find a braided shield that the guy from the local electronics store says is the same magnetic shielding that’s used in the sheathing. I did have it wired up (when testing) with nothing than a flex conduit for the motor leads and I think it was fine. This is my first VFD so what do I know anyways!


Any who, I’m going to start wiring today after work and finding a permanent home for everything. I’ll try and post some pics to get feedback on placement. I think I have a good idea of what to put where and more importantly not to put where.

Best,

Taki

Hey folks!

So I’ve been slammed at work, but have been trying to chip away at getting the VFD project done. I’m pretty close to completion. There’s some stuff that I’d love to say in going to remove and paint, but let’s be honest... I’m not

Thank you to all those you chimed in, I’d still be chasing my tail. I want to shout out to Mark especially for the time he’s spent making PDF’s with programming and parameter information, his willingness to help and share that info.

I’ll post some pics once I get all the covers back on.

If not before the holidays, hope everyone has a great Christmas and a Happy & Healthy New Year!

Taki,

Well she’s up and running! I got a MachTach that I still have to wire up, I’m having trouble with placement for the photo sensor, so if anyone has any input please share.

Here are some progress pics.

I must say, I set the jog frequency really low and using a tap or die stock for threading is great! I did finally cut some threads with a threading tool finally, honestly wasn’t that bad once I figured out I should reverse lol!

WARNING: This is complete crap compared to Marks installs....
