I/O Filtering

I/O filtering, while not a necessity for CE compliance, may be desirable

(depending on system installation, application, and integration with other

equipment). To avoid unwanted signals entering and disturbing the drive system

or other associated equipment, place ferrite cores on I/O lines. The following

chart lists some recommended ferrite parts used for I/O filtering and noise

attenuation. These parts are ideal for providing an in-line common mode

impedance for I/O lines (Fair-Rite Products Corporation also has a varied

selection for most applications).

* This core must be used with the CD-Series of drives for CE compliance.

It should be applied to the 24 V input power lines and the Remote Enable

lines (7 & 8 on C3 connector) with approximately three turns through the

core.

The following figure illustrates the use of multiple turns through a clamp-on

core. The more turns created, the more impedance is added to the line. Avoid

putting the shield in a clamp-on core. It is undesirable to place an impedance in-

line with the shield. The use of ribbon cable may be common in many cabinets.

Some ferrite clamps are designed just for ribbon cable use.
