Chapter 6 SERVICE AND MAINTENANCE
Because of its solid state design, the 590 DRV Digital drive has few items requiring service or maintenance. Service
typically is a matter of replacing fuses, checking electrical contacts, and isolating problems in the overall system
application.
Caution
Service procedures must be performed by qualified personnel with an understanding of the dangers inherent
in high voltage applications and the precautions necessary when servicing industrial equipment. The
customer is responsible for assessing the technical competency of in-house service personnel.
