WIRING
The environment that any electronic control system ‘lives’ in can effect its
operation. Danaher Motion Kollmorgen recommends that the SERVOSTAR
system be operated and stored under the environmental conditions stated in the
product specification tables. The system may be operated in higher temperature
ambient conditions with a derating applied. Please check with the factory for
derating information.
Attention to proper installation and field wiring are of prime importance to
ensure long-term and trouble-free operation. Users should familiarize
themselves with and follow the installation and wiring instructions listed in this
section. In addition to these practices, some localities and industries may require
applicable electrical and safety codes, laws, and standards.
Particular care should be used when layout of an enclosure is designed. Efforts
to separate power wires from small signal wires should be taken. The following
guidelines highlight some important wiring practices to implement:
• Control and signal cables must be separated from power and motor cables.
Distance of 20 cm (8 in.) is sufficient in most cases.
• Control and signal cables must be shielded to reduce the effects of radiated
interference.
• Where control cables must cross power or motor cables, they should cross
at a 90º angle, if possible. This reduces the field coupling effect.
Enclosure
The Danaher Motion Kollmorgen SERVOSTAR series of electronic system
components are designed for panel assembly. This panel assembly should then
be mounted in a metallic enclosure. Enclosures are supplied by the
manufacturers of the final product and must meet the environmental IP rating of
the end product. To ensure proper grounding (and to optimize EMC), the
enclosure should have continuous ground continuity maintained between all
metal panels. This ground continuity is intended to be both a safety ground and a
high frequency ground. The units should be mounted on a back plane, which is
installed into the enclosure. Ideally, the back plane should be an unpainted
metallic surface to optimize electrical bonding of the frame and provide the
lowest possible impedance path to earth ground. These enclosures also provide
added safety.
