FBM227 P0927AC Output module

EMC testing was performed using a single drive with standard wiring. When a machine incorporates several drives or is designed for use in an environment requiring very low emissions, additional steps may be necessary to reduce the overall machine emissions and/or susceptibility. High frequency grounding of cable shields may help reduce radiated and conducted emissions as well as protect against susceptibility to external and selfgenerated noise. High Frequency Grounding of Cable Shields NOTE When a cable with a separate inner foil shield and outer braided shield is used, EMC performance may be improved by connecting the foil shield to the PE location on the connector and removing about 10 mm (0.5 in) of the outer cable jacket close to the drive [within 0.6 m (2 ft) of the drive] to expose the braided shield and clamping the outer braided shield to the ground plane with a 360°- type clamp. If a ground plane is available at the motor end of these cables, similar use of a conductive clamp at that end to connect the shield to the ground plane may help as well. Clamping the cable shields to PE typically reduces the level of emissions and increases the level of immunity to interference. Example of 360° clamping of cable shields

REGEN RESISTOR

 Regen Wiring (AC drives) For complete instructions pertaining to an external regen resistor with an AC input drive, refer to Base AC Drive Wiring. In addition to the information in that section, users installing drives for use in a CE installation should use an appropriately-grounded, shielded regen cable to reduce overall system emissions. Accessible Regen Cables CAUTION When using an external regen resistor, if regen cabling is accessible during normal machine operation, the cable should be a shielded cable rated at 450 VDC with the shield connected to PE. High Frequency Grounding of Regen Cable Shield NOTE When using a regen resistor in a CE installation, the cable should be appropriately rated and have a braided shield connected to PE for safety, and clamped to the ground plane with a 360° clamp for EMC purposes
