8.2.5 MOTOR WIRING RECOMMENDATIONS
Wire section
The minimum wire section is determined by the motor current. It is preferred to use wide section stranded wires to reduce impedance, power losses and ease the
assembly. Insulator size should not exceed 5 mm (connector pitch). Following table indicates recommended section:

Wire length
The distance between the Jupiter Servo Drive and the motor
. Short cables are preferred since they reduce power losses as well
should be minimized when possible
as electromagnetic emissions and immunity.
Avoid running motor wires in parallel with other wires for long distances, especially feedback and signal wires.
The parasitic capacitance between motor wires should not exceed 10 nF. If very long cables (> 100 meters) are used, this condition may not be met. In this case,
add series inductors between the Jupiter outputs and the cable. The inductors must be magnetically shielded, and must be rated for the motor surge current.
Typically the necessary values are around 100 μH.
Wire ferrules
It is recommended to use wire ferrules to prevent cable damage or wrong contacts. Ensure crimped ferrule diameter does not exceed 2.5 mm and the insulator is <
5 mm. Following are some suggested ferrules:
