1. Introduction
Complex cabling places a limitation on servo system design. The precision actuators in servo systems have multiple connections with other motors, a centralized controller, a power source, etc. For servo systems, housing and guidance become problems during, the design phase. It is important that the cabling not restrict the bending and twisting connections. Thus, the cable guidance can become so complicated that automated’ installation is not possible. Such complex designs become problematic when maintenance is required as it may be inconvenient to repair cables without taking the entire machine off-line. Cabling contributes to higher material, manufacturing, and maintenance costs as well-as increased weight and bulk. The number of problems associated with cabling varies directly with the increasing number of axes in an apparatus.
