3.4.2 AC input and regeneration resistor output wiring
The installation methods shown in Figure 7 will improve the reliability of the system, reduce
troubleshooting time, and optimize the EMC (electromagnetic compatibility) behavior of the
control system. The MotiFlex
e
100’s protective earth connection does not provide
electromagnetic compatibility. Its purpose is to prevent exposed metalwork becoming live in the
case of a serious failure. To avoid EMC coupled effects within the panel design:
1. Do not run AC filter input and output power cables in close proximity.
2. Do not run motor output power cables with any other cables, especially Ethernet, signal
cables, or ’clean’ AC power.
3. Do not run power and signal cables in the same trunking. If the cables must run in parallel,
they should be separated by 200 mm (8 in) or placed in separate metal trunking.
4. If any of the above cables must cross, they must do so at 90 degrees to minimize coupling.
5. Ensure all sources of electrical noise are suppressed, e.g. solenoids, relays, contactors.
