AC30 series Variable Speed Inverter
You should already have planned your cable routes with respect to segregating these cables for EMC compliance.
•
Use the shortest possible motor cable lengths.
•
When connecting multiple motors to a single VSD, use a star junction point for motor cable connections. Use a metal box with
entry and exit cable glands to maintain shield integrity.
•
Keep electrically noisy and sensitive cables apart.
•
Keep electrically noisy and sensitive parallel cable runs to a minimum. Separate parallel cable runs by at least 0.25 metres. For
runs longer than 10 meters, separation should be increased proportionally. For example if the parallel runs were 50m, then the
separation would be (50/10) x 0.25m = 1.25m.
•
Sensitive cables should cross noisy cables at 90
°
.
•
Never run sensitive cables close or parallel to the motor, dc link and braking chopper circuit for any distance.
•
Never run supply, dc link or motor cables in the same bundle as the signal/control and feedback cables, even if they are
screened.
•
Ensure EMC filter input and output cables are separately routed and do not couple across the filter.
