Re: [Emc-users] Retrofitting scara robot
50% sounds high! manufacturers are NOT interested in old equipment running. what i got is scrounged off service techs and the web. hey, thx for the reality check if i tried to keep those encoders, i'd need spcl code to read them, plus they need an initialization messaging on startup and home. replacing them is smart thx tomp tjtr33 On 09/09/2014 04:08 PM, Marius Alksnys wrote: On 2014.09.09 23:26, TJoseph Powderly wrote: get something with documents its not just the motor and driver that can bite you.

Re: [Emc-users] Retrofitting scara robot
Marius get something with documents its not just the motor and driver that can bite you. i got a 6dof with Sanyo Denki planetary drives and the encoder output is proprietary 'panasonic A' never did get that decoded i have screenshots and devices to capture the data hm, hey! I got a cheap robot for you ;) just kidding best of luck TomP tjtr33 09/09/2014 02:50 PM, Marius Alksnys wrote: > Maybe someone knows what motors are in these robots?

If voltage/current is higher than the 7i30 can do then the Pico amps are an option, The Mesa 8i20 (2.2kW) is probably overkill.
