Hi,
I agree.
In detail it depends on a lot of parameters.
If you have high dV/dt at the motor signals it may produce a lot of EMI. Especially with 10m of not suitable cables.
If you run the motor lines for 10m then I recommend to use a simple filter on the driver side (to decrease dV/dt) and use twisted pair cables.
But i tend to prefer short cables to the motor. But then the control lines are the problem. If there is EMI from other devices it may affect signal reliability.
Therefore I´d use differential signaling like RS485 and a CAT6 cable.
Depending on noise in environment: ESD protection, surge protection, galvanic isolation.
