Servo motor installation considerations
Servo motor installation considerations
(OP)
We are about to install a machine with more than 40 servomotors (don´t know the size/ratings of the motors, but they should be equivalent to about 1-2 HP each), and most of the servodrives will be installed in a main control cabinet located about 50 meters from motors. I´m somewhat concerned about problems we could have with all those motors, their cables, EMI/RFI, power quality, etc., because we have had very little experience with machines having that many servo axis, the most we´ve had is 10 in a single machine, and the motors were located pretty close to the drives in that case.
The only special servo-related preliminary installation guideline we´ve received from the manufacturer so far indicates that we should run two separate trays for motor cabling, one for resolver cables and the other for motor cables, separated at least 30 cms from each other.
Obviously grounds are very important, as well as ferrite "doughnuts" on motor power cables, but what other guidelines should we follow and ask thye manufacturer to follow? Any web reference somewhere? Thanks..

RE: Servo motor installation considerations
Some suggestions:
1. Motor / signal cable separation 10cm for every 10M of cabling.
2. Twist motor power leads and ground at a common point near amplifier.
3. DC power supplies could use an additional 1000uf of capacitance if PS is located more than about 3 ft. from the drive.
See the following link for various tips on servo / drives / wiring.

In a hundred years, it isn't going to matter anyway.

At the price of copper these days it might be less expensive too.
