A.1 ELECTRICAL INTERFERENCE PROBLEMS
Electrical interference problems are common with today’s computer-based controls. Such
problems are often difficult to diagnose and cure. If such a problem occurs with your
system, it is recommended that the following checks be made to locate the cause of the
problem.
1. Check the quality of the AC line voltage using an oscilloscope and a line monitor. If
line voltage problems exist, use appropriate line conditioning, such as line filters or
isolation transformers.
2. Be certain all recommended wiring practices are followed for location, grounding,
wiring and relay suppression (see Section 3.1).
3. Double-check the grounding connections to be sure they are good electrical
connections and as short and direct as possible.
4. Try operating the drive with all suspected noise sources switched off. If the drive
functions properly, switch the noise sources on again, one at a time, and try to isolate
the one(s) causing the interference problems. When a noise source is located, try
rerouting wiring, suppressing relays or other measures to eliminate the problem.
