every thing you need to get running!
the galil mach combination is great. easy to set up if you can follow a manual. and some good help on cnc zone and here from kcrouch & smurf

just looked at wiring and specs.
has inerter got wire going to inputs 8,10 at the moment ie 10v analogue or is it wired to inputs s0+ so- (rs485)


your inverter has a max frequency of 650 hz. (or if later software 1300 hz) thats high! 24000 rpm is normally at 400hz on router spindles
you will probably have parameters to set max frequency of output.
if you want max speed to be 24000 rpm etc this would have to be set so +10v gives 24000 etc
obviously if your powering drill spindle, saw spindle etc you will have to ensure your max analogue voltage commanded doesnt exceed the motor speed (probably about 1v peak to give 2400 rpm) or whatever speed that motor should run at.
if its already running as analogue you shouldnt have to change much. if its running rs485 at present you may have to set parameters

my machine is on you tube. see biessebod . not shown under mach control yet as its a work in progress. i need to use the machine daily until im happy to rip out the old controller. i have the new one as a plug in test bed on flying leads.
working on the tool changer macro at the moment. it looks easy if you watch the video but there is a long list of i/o and etc etc to consider.

re galil controller. are you buying new? ebay seller "athomemarket" has lots of regular galil products for peanuts. i have 5 axis controllers from them for about $150
everything i have had from them is brand new old stock.
galil rio works well for extra i/o
there are always breakout boards on ebay etc.
i just got a brand new 2280 controller for $300 instead of $3000+
i use the icm 1900 . can be any voltage i/o if configured correctly

my biesse uses a relay to "ignite" the inverter from a plc output . and then others to switch specific routers on ***spindle routing output circuit must be made before inverter is switched on or damage may be made to inverter***
also has a emergency signal, inverter inhibit "run" signal and thermal overload sence from router head input to overcome to get to run
its worth checking that the main circuit voltage circuit is permanantly live or also switched by plc output. obviously without this it wont run

if you check circuit diagram you should find a series loop of emergency/ over temp/ run signal to inverter input.

you will probably find the servo motor has a tach and encoder, or like you said encoder on axis.
the drive may require the tach i dont know but the galil will take the encoder output only. very easy to wire in. but make sure you follow instructions re first switch on exactly as motors seem to run away until set correctly.
 i can help with galil startup tuning parameters etc and what i found re tuning as i made notes.
the i/o is a bit of a pain in mach as you have to use vb.macros  i edited samples of code i found on this forum rather than learn it from scratch

how much did you pay for your antique or is that like asking how old the wife is?

re the spindles
1. a lot of the inverters are signaled by rs485 on italian machines. check the inverter inputs for analogue are connected. you may need to reprogram the inverter to accept analogue instead of rs 485 if thats the case. what inverter is it? is it a single inverter machine, relay switched to each router motor etc? (as biesse is)
if its rs communication you will have to find the right code to get existing controller to switch it on.
mine requires vacuum pump to be running , sufficient air pressure etc before it will do anything
can you get a start light on it? ie drives switched on from plc ready to run.

it may have a weird button combination like biesse. "start, stop, reset" to switch on vavuum pump (i had to get a biesse tech to tell me that when i first got mine as i couldnt switch it on) also all axis must be global reset ie. homed before anything else will work. on a biesse this is done on the manual screen.

do you have a user manual or wiring diagram for the machine? if not try to buy or steal one. as lots will take ages to work out without one.
mine uses rs485 for i/o communication to all the i/o boards scattered around the machine


also you need to work out its power up sequence. a lot of this sort of machine have timer relays etc. you should find these in the cab

i know its not a biesse, im trying to point out what i found with mine, as its italian too.
are you going to try to run it as is or convert straight to mach etc?
if converting to mach, what are your ideas for conversion so far?
 its definately quite a big job as i found out.


there is normally a manual plc screen where you can switch each output on. air rams, drills down etc.

IF YOU CAN PULL UP THE FIXED CYCLES SCREEN YOU SHOULD BE ABLE TO WORK OUT HOW TO GET ROUTERS TO SPIN
ON A BIESSE IT PULLS UP FIXED CYCLE PON  BY USING L=PON
I READ ALL FIXED CYCLES TO CONFIRM LOGIC HANDLING ETC ON MINE.

im using a galil controller via mach whicg gives very smooth movement on the servos. well worth the money and its fully closed loop.
so many i/o to handle though! has it got an atc on it?

its the same layout as some of the very old biesse too.
if its anything like biesse theres a lot of i/o controlled by serial communication including the inverter.

Galil / Re: Mitsubishi HF-SE Ac servos and drives.

« on: February 15, 2010, 04:46:37 AM »

yesterday i set up some cheapie ebay yaskawa sgd s drives. couldnt be simpler!
started with all drive parameters as standard apart from setting 300rpm per volt
with all the pid on galil set to 0 letting the drive tuning take over. (although my drives arent tuned quite right yet as i was bench running them they were holding around 1 to 2 encoder counts off. which is a little annoying in mach as the 4th decimal place dithers a bit)
another very smooth combination. im sure once the servos are auto tuned correcltly they will be nearly as nice as the mistsubishi (but cheaper)
the only thing id say against the yaskawa is the requirement of an external 24v for the i/o whereas the mitsubishi has this onboard.
thanks to artsoft mach and galil we can all have totally accurate fully closed loop control now. thanks for all your hard work guys!

by the way i have a candcnc unit here but its not a stand alone unit. it works with their interface and breakout only and outputs step/dir to motors only
i dont like the way their auto install removes any other saved profiles from mach so only their stuff turns up in mach loader!
they use serial com port for speed required to update.
