The various propagation routes are shown in Figure A.2.

    Figure A.5 Electrostatic Noise (3) Radiation noise Noise generated in an inverter may be radiated through the air from wires (that act as antennas) at the input and output sides of the inverter.

The basic measures for lessening the effect of noise at the receiving side include: Separating the main circuit wiring from the control circuit wiring, avoiding noise effect.
  • Page 267 What follows is noise prevention measures for the inverter drive configuration. (1) Wiring and grounding As shown in Figure A.7, separate the main circuit wiring from control circuit wiring as far as possible regardless of being located inside or outside the system control panel containing an inverter.

    App. G Replacement Information Function codes This section describes the replacement information related to function codes that are required when replacing the conventional inverter series (e.g., FVR-C9S and FVR-C11S) with the FRENIC-Mini series. It also provides the conversion table for the torque boost setting. FVR-C9S vs.
