It looks like you basically have two options to use that motor drive with our KFlop Controller. Either command the motor driver open loop with Step + Direction signals much like a Stepper Driver (a footnote seems to indicate it accepts Step + Direction as well as CW and CCW pulses).. Or command the driver with a +/-10V Analog velocity command and feed the encoder signals back to our KFLOP+Kanalog boards and have KFLOP close the position loop. My preference would be the second choice where our software and diagnostics could be used to tune and monitor the servo performance. It looks like the encoder signals would need to be paralleled to both the Servo drive and our Kanalog board as the position information is needed for both.
I hope this helps. TK

So are the signals of my servo amp and the motor standard?
Would it make any sense to buy new servo amps.? I guess what I am trying to say is: what is the likelihood that this would work with the kflop?
Thanks for your prompt response.

Hi Vetsen,
Yes +/- 10V analog signals are very common and standard. As are the differential encoder signals going from the motor to the drive. It is very likely to work with KFlop+Kanalog. But the document you supplied on the amps does not provide details on how to configure the various modes. You would need to research it further. To test if the Amp is configured correctly you could apply a small voltage to the input. Possibly even a 1.5V battery. The motor should run at a controlled speed of 15% of full speed. Reversing the battery to apply a negative voltage should cause the direction to reverse. If that works it would almost certainly work with KFlop+Kanalog.
