Greetings all; I've managed to get up to the top shelf and get the spindle control wires hooked up.
This vfd's control board terminal markings are fairly conventional, even in English no less, however it has many more registers, nearly 200, to configure how it runs. I did have it so I could run it manually but that seems to have gone away now. No clue why, unless I have to zero r032. I have a table of its registers and hints at least as to what they do. For instance r000 is defaulted to 50 hz, which may be the minimum speed limit maybe. Dunno, but its a factory default. r001 is set to one, which allows writes to the rest of the registers. The next register for this purpose, is r031, which if set to 4, which I have done, causes it, if I'm reading between the lines correctly, to treat the AVC input as a PWM signal. And finally r032=1 for external control, 0 for front panel. And I am feeding it with a 500 pulse per second pwm, ranging up to about a 60% duty cycle in my tests so far, of a good solid 5 volt signal from the bob. I am feeding it a good solid 5 volts on the FWD terminal when the right hand start icon is clicked, and am hitting the REV terminal with another 5 volt signal AT the same time if I click on the CCW icon. This is treating the FWD terminal as a run signal, which may not be correct. Ground is also marked well and has been made common to the ground on the bob. The motor is not being tickled a bit. Grab the collet nut and its electrically free to be turned either way. And the Chinese are not sharing anything else about this vfd. I think they are afraid some beginner will fry it if they give him any info. Its equipt with small but FAST nema-23 motors for all 4 axises, with the 14 volt TB6560's out of circuit, replaced by a quartet of 2m542's fed 28 volts, its perking along at 90 IPM on all 3 linear axises, using software stepping from one of those magic d525mw intel mobo's. There is a 5i25 board installed in that computer, but I've not yet carved an exit slot for the p2 cable, which I'll need as the interface box I'm building for the g0704 will be duplicated at some point to run this 6040. Does anyone have a clue how to make this thing run its fancy 1500 watt watercooled spindle? I could probably replace both the spindle motor and the vfd from ebay, but this is all 127 volt stuff! Plugs into a std 15 amp 127 volt wall plug. Many thanks for any clues from someone WHO HAS ACTUALLY DONE this. from the cnczone forum, it appears most have bought it for a usb control, and since pwm doesn't go thru usb, all mach can do to it is start and stop it with the relay on their bob. Speed control is left to the knob on the power boxes control panel when its turned on. With the BS on this control thats available on the cnczone, and 60" of rain on good black Iowa dirt, I could raise 300 bushels of corn per acre, or 150 bushels of soybeans. I don't believe I've read a msg there yet from somebody who actually KNOWS what he is doing. And I'm slightly amazed, I can get the same voltage motor, 1500 watt, er11, water cooled, and a 120 volt vfd from ebay, for $220 with free shipping from LA. Awfull tempting as it will run off a std wall plug. Cheers all, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
