Cables and Cable Chain Procedures
If your positioning stage is supplied with a cable chain, follow these recommendations
regarding its use:
S Your stage is supplied with high flex cables that are designed to withstand
millions of bend cycles. In addition, the internal conductors of the cable are
twisted and shielded. A twisted, shielded cable reduces the problems
associated with EMI and EFI noise. Using other types of cable may cause
difficultly during servo tune procedure. Baldor recommends that any additional
cables installed into the cable chain conform to this standard.
S The cable chain must never be more than 80% filled. Additional cables,
pneumatic hoses, etc. contained by the cable chain require enough space to
freely bend and conform to the cable chain without kinking or cork screwing as
the stage cycles. The cables and pneumatic hoses must be installed without
twists and should never be put on top of one another in high velocity and high
cycle applications.
S If your stage was provided with flying leads, Baldor recommends that the cables
be strain relieved, i.e. clamp the cables as they exit the cable chain to relieve
tensile loads. Be sure not to pull the cables out of the cable chain making them
“taut” inside the chain. Allow the cables to freely lay within the cable chain and
find their natural position.
S To install additional cables and pneumatic hoses you must open one side of the
cable chain. Typically the side of the cable chain facing the cable chain tray is
the side that opens. Gently pull one end of the removable side toward the
opposite end of the cable chain. Slowly pull the removable side loose,
detaching the plastic segments. The segments are loosely attached to each
other and may become separated. Be careful that the segments are not lost.
To re–install the cable chain segments, it is recommended that a section of
three or four segments be done at a time. Once a section is installed,
additional sections can be easily assembled into place.
S Baldor recommends that you inspect the cables and pneumatic hoses during
regular maintenance procedures.
Note: If your cable chain is not large enough to accommodate your cables and
pneumatic hoses, please contact Baldor for assistance.
