Hi Irfan,

thanks for the reply - last night i soldered the 3 pcbs - nearly ready

only nearly because:
i got 3 kits with different parts

i.e. the resistors with a value of 470R are only in...

Hi,

today i got my 3 HP-UHU-Kits :-)

what is the maximum tested voltage ?
My Maho has DC-Servo with a nominal voltage of 170V DC

are there any complete documentation on board rev. 10b ?...

Hi Dave,

here are two pictures

the heidenhain EXE: (very analog - a lot of LM339 :-) )

Dave,

i still use the indramat power stage and the resolver on back of servos.
(servo motors too)

(1) at the beginning i also use the heidenhain EXE to get encoder-like incremental signal from...

Hi all,

a friend asked me how to reset the c-Axis on a extendes lathe to 0 after one rotation (360°)

i've tried a lot of settings in his PP (other changes in the past years i've done without...

Andy,



the voltage of the motordata is given for continous current (static) voltage. But the geckos will chop the voltage
so, that's ok, because the current has to rise inside the coil as fast...

Hi Happytriger,

I know, that there a different drives availiable - but mine didn't support Step & Dir.
You're inverting the signals, but if your driver need explicent clock for CW and CCW your...

Hi Happytriger,

the normal application of a driver to the LPT-Port is known I think.
But the UDX need an explicent step for CW and CCW rotation
on a change from low to high at CW-pin the motor...

Hi happytriger,

I've just got several of these UDX-Drives.
To use them with Clk/Dir-Pinout I take a CMOS-Analog-Switch to get a CW-Clk-signal and another switch with an inverter in front to get...
