Here is the schematics and wiring diagram I received.

Here is some E-mail corrispondance reguarding a spindle I am having issues with. Hopefully someone smarter than I can help out?

Alrighty, below are my settings on the Hitachi WJ200 VFD - for some reason the spindle has yet to turn at any usable speed. I have tested the conductors at the end of the VFD cable to ensure proper conduction was produced at the motor - all leads tested normal and with constant Hz and Voltage when applied. My test was at 60 Hz and I fell between ~2Hz of that threshold constant. I feel it safe to assume that the VFD is in excellent working order.

a001=2
f001=60
a002=2
a003=400
a004=400
a082=220
b012=8
h004=2

Is there something I am missing? Thank you for your time!

a001=2
f001=60 this has to be 400
a002=2
a003=400
a004=400
a082=220
b012=8
h004=2


F001=400 this needs to be set at 400

On my wj200 F001 controls motor speed. 60hz should net 360 rpm.

What type of spindle motor are you running

It depends what motor you are running as to what the settings have to be, if your motor is 60Hz rated then you have the right setting

The spindle motors that are 400Hz rated, this parameter needs to be set at 400Hz

[jckstrthmghty]

Correct me if I am wrong but if the motor is rated at 60hz then the settings should be

A003 - 60hz (Base Frequency)
A004 - 60hz (Max Frequency)
F001 - 0-60hz (Output Frequency Setting)

I run a .8kw air cooled spindle 400hz 24000rpm that is running off a WJ002-007MF. Works perfect.

With those settings the 60Hz motor would run at rated RPM , to go faster than the rated RPM the A004 - 60hz (Max Frequency) would have to be changed to a larger number depending on the AC motor you were using, 120Hz in that setting would double the motors rated RPM, most AC 60hz motors can take up to 120Hz max , but depends on how well the motor has been built

Well it seems this thread is still active so here is a question. I'm looking for a spindle to convert my Joe 4x4 wood working machine away from a router. Ultimately I'm looking to swing a 1"d x 6"LOA end mill which I think means a ER40 collet size. Looking to keep the spindle in the 2.2-3KW range. Is this combination possible? Assume I know nothing about spindles (which is actually pretty accurate). Any suggestions on how to start along this new leg of my CNC journey?

Thanks
