ServoDrive Parameters

04/05/2012 10:37 PM

I have connected up a servo motor to a manual dividing head to automate simple indexing on a CNC mill. All works great except that to alter the Servo Drive parameters I understand the commands need to be sent in binary code ? I have the ability to output ascii code via the program to rs232 is it possible to send binary as well or do i need another interface ? Any help would be appreciated.

Thanks

The question has no meaning. Theres no such thing as running a "servo motor" from a computer.

Its a "servo SYSTEM"

The motor could care less what data format is sent, the interface between the computer and motor is where the question is, and no information has been supplied about that.

ASCII is binary data. ASCII and RS 232 are transmission formats, not data.

-232 is a container. data is whats in it.

True, but a little unkind, since the OP does not even mention 'running a "servo motor"', though he does say "All works great".
There is a table of ASCII and binary equivalents at

http://www.pcguide.com/res/tablesASCII-c.html

from which you can see that many, but not all, binary commands can be sent as ASCII codes from a keyboard. If you need some extended codes and your terminal program allows it, then the command numbers may have to be sent in hexadecimal format rather than ASCII. They will all come out in binary format at the servo motor end.
