AXBB-E, Integrated Servo Motors and Noise

[flugzeug]

I am retrofitting an older router and as always there came up the challenge of making the whole system reliable and as little susceptible to issues with noise as possible.

I decided to go with AXBB-E controller and iSV57T integrated servo motors from Stepperonline (very similar to iHSV57 integrated servos from JMC).

Servo manual: https://www.omc-stepperonline.com/download/iSV57T.pdf

Unfortunately AXBB-E doesn't have differential outputs for step/dir signals and I assume that running a single ended signal through a 4 meter long drag chain that is already packed with other cables (inductive proximity sensors, spindle and motor power cables) will cause issues.

Should I go with a single ended to differential module or what would be the most optimal and reliable solution?

Ofcourse single ended signal is more sensitive to noise than differential.
You could use for example this module to convert the sindle ended lines to differential: http://cncdrive.com/Difflinedriver.html
