General Mach Discussion / Parker Servo Feedback Connector Help ??

« on: February 04, 2017, 04:40:38 PM »

 Hi guys I'm trying to get a Parker SME82 Servo motor to work with a Parker Gemini GV6 - U12E drive, I have been trying for weeks now to get this darn thing to work however Im stuck on a problem with the Hall effects, I have wired the cable up to the diagrams I could find and have tested each pin for continuity, I can successfully communicate with the drive via rs-232 and program it, when I issue a DMODE13 command which configures the drive to run the motor open loop at 1rps it turns in the correct direction so the motor phases are wired correctly, the problem comes when I want to switch the drive to position mode (DMODE12), when the command is entered the drive will not enable and the error report (TASXF) shows bit21 which indicates a bad hall state, I have consulted every manual under the sun to no avail as they all say to check wiring  The motor in question has a tamagawa 2048ppr encoder which has 3 hall effects that are differential outputs, as the drive seems to only accept single ended hall signals I contacted parker directly and they said i should wire the positive pins to the drive and leave the negative pins disconnected (A- B- C-) however the drive still refuses to play ball, if anyone can help me it would be greatly appreciated as I'm scratching my head at this point, I have added some photos however it's difficult to see the wiring due to the spacing of the wires however there are no short circuits, the soldering looks a little rough due to impurities floating to the top of the soldercup as the pins are hollow, the copper conductor goes at least 5mm into each solder cup and is filled with solder.

Found a link to a manual of a drive i posted earlier (compax3) : https://www.google.co.uk/url?sa=t&source=web&rct=j&url=http://www.compumotor.com/manuals/Hauser/Compax3/Compax3_Single-Axis_UG_Feb_2004.pdf&ved=0ahUKEwjFza6b4vvOAhUkKsAKHblXBGgQFgggMAI&usg=AFQjCNEcaiQHBIaeHQDCWKxbaBEOePlZDA&sig2=_dDwzPyMLFfDJ8iI9sGaUQ


It supports sin cos feedback, just about the right amperage for my motor however i havent got a clue what profibus dp is, not sure whether you can alter it to step/dir to be compatible with the ESS

Thanks for the reply Hood, i too got extremely confused over there website and got frustrated looking for specs so i messaged customer service at Parker for a list of compatible drives, hopefully they will be able to help me, the seller also thinks the motor is 5200 rpm max so that should be way fast enough for a spindle as i dont plan on turning any tiny parts.

Thanks for the replys guys, did some digging from what i could find this motor has encoder feedback, had a look at the vix and aries series drivers but there are quite a few and im not quite sure which one is the right one, also spotted a few compax drives from parker which will run on 240Vac which is a requirement as i dont have 3 phase at home, this is the drive i found but i have no idea whether its compatible with this motor   Look at this on eBay  http://www.ebay.de/itm/252179487130  hopefully this motor will end up as a spindle for my lathe alongside the panasonic motor mentioned in my other post  

Just also found this Look at this on eBay  http://www.ebay.de/itm/262051282902
What confused me is on the motor label the wattage according to the v and a rms is 618w where as the Pn is 1.04kw is this the peak the motor will run at? Will it run at just over 600w until you push it to its maximum? Dont want to be blowing an expensive drive, the aries drive is 750w according to the order code, hmm

Hi guys looking for advice towards what model drive i should use to power this motor? The motor is a Parker SME82, had a look round but got lost trying to find a compatible drive for a decent price, cheers     

Link to where i bought it:-    Look at this on eBay  http://www.ebay.co.uk/itm/182199423112

That's a pretty cool feature wouldn't want the head of a machine to crush you incase of a power failure, thanks for your help getting the motor running, did some speed tests and torque tests, 3000rpm can't hardly hear it also the torque is insane compared to a stepper motor, looking to get the torque monitor output hooked upto an led bargraph maybe an LM391 driver

Guess I was a silly billy indeed the dynamic break wanted 24v to disengage I thought it needed 24v to engage  , oops rookie mistake haha

It doesn't show an error the LED display just flashes and you have to reboot the drive

Okay thanks a lot managed to get the motor running with mach  , getting some problems with the drive tripping, wondering if it's tuning, the motor is making a subtle whistling sound and at different velocitys in mach it squeals periodically, at low rpm it seems fine however the drive trips randomly, regenerative energy maybe?
