Baldor iMN1800 manual Cables and Cable Chain Procedures

Cables and Cable Chain Procedures

If your positioning stage is supplied with a cable chain, follow these recommendations regarding its use:

SYour 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.

SThe 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.

SIf 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.

STo 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.

SBaldor 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.
