The basic controls seem pretty simple needing signals to start- forwards, start-reverse, stop, 0-5v or 0-10v to control speed.  There are a host of other options, features etc but listed are what I would really like to have working in the immediate future.


I have 4 Step & Direction controlled axis hanging off the Kflop's JP5, and now an empty KAnalog hanging off JP7.


Q1) I Have another Step and Direction axis which presumably now will need to come from the KAnalog? I am using step generators 0-3 already and I am not sure where it should go or how it will be addressed?


Q2) The D700 documentation is explicit about not connecting various "common" interfaces to either ground or earth.  I.E. the Start-F, Start-R, STOP all share a common connection as do the analogue speed input and output lines.   Should this explicit warning be ignored and each of these actually go back to ground on the KAnalog?

I think I have got the number of the step generators wrong in my question, currently Axis 0 uses JP5 pins 1&2 and channel 4  (which I think is step/dir generator 4).

Hi,

Regarding:

Q1 - KFLOP JP5 Has 4 Step/Direction generators available (channels 4 - 7) that are capable of driving 4 motor drives.  Kanalog does not have any Step/Dir outputs.  Kanalog was mainly designed to be used with Analog Servo Drives.  If you need more than 4 Step/Di drives you will need to multiplex the Step/Dir Generators that by default are on KFLOP JP7 to JP4 and JP6.  See:

http://www.dynomotion.com/Help/StepAndDirection/StepAndDir.htm


Q2 - There isn't enough information to answer the question.  Do you have a manual for the VFD?  Kanalog has isolated OPTO Outputs that you might use for Start-F, Start-R, STOP to avoid a GND connection.  Depending on the input requirement of the VFD thos might be used.  The Kanalog Analog signals will require a GND connection for those.

I think I understand how to implement your answer to Q1, I will give it a go and get back to you.

Thanks.
