Hi!!! stepper always consume amps. so, have to add values of all drives. But! remember: you have motors, so, question is how to have maximum safe power of motors. your Keling's 425 oz stepper...

Hi!!! my operator remove relay from PCB for manteinance but didn see some are NC and other NO. Does anyone have a photo, schem or diagram of their position? thanks!!!

Hi!!!! same opinion. Once used G540 with 24Volts and no reliable high speed was reach. Lost money changed hardware. If you want high speed you should use ballscrews and servos. I use once steppers...

Hi!!! I am from Mexico and have similar lathe. by mistake remove relays from PCB and machine is not working. Can you help me telling me order of 17 and 25 type relays? thanks!!

Hi!!! I am form Mexico too and have similar lathe. by mistake remove relays from PCB and machine is not working. Can you help me telling me order of 17 and 25 type relays? thanks!!

Sure. No problem, been working with yaskawa drives for about 3 years. This one was a headacke! but I can help you on your machine

Hi!!! rthanks for reply. Certantly was a parameter error, electronic gear was originally 4:1 and pulses above 1200 per mm. Finally used about 13.15 and pulses get down to about 98. So with SS can...

Hi!!! no, I havent. Try to use electronic gear on SGDV and same result, no matter wich relation I use, always motors stalls at 550 RPM or so. I think is a pulse error, but using eletronic gear I...

Hi!! Have a router with 2 SDGV and 1 SGDM yaskawa servopacks. Change them to work with mach3 (before this all work great, but software was obsolete). Change Parameters on drives for position...

hi! I have a grinding machine configured with:
Mach3

all works...

Hi!!! I just finished a Gecko drive and homeshop 1200 oz/in retrofit. I used a 70 volts 1500 watts power supply from Antek.inc At slow speed all works fine, but when I increase it motors stop. If I...

thanks for the response!! but I still have a question: it is possible to make a follow up of position and speed of the spindle with an encoder an a G-Rex or PMDX? a mind for threading.

Hi! I want to retrofit a Lathe with 2 axis movement. I want to use a stepper for the spindle movement (rotation). is it possible to make a continious movement at high speed (about 1300 RPM) on large...
