Static and Dynamic Poles/Pendants

Static or dynamic terminology refers to the pole or pendant length when the luminaire is located. In either case, the mounting height specifies the location of the insertion point of the luminaire symbol in space. Pendants and Poles are always attached to the luminaire symbol at its insertion point.

• Poles are Dynamic by default attached to Z=0.

• Pendants are Static by default with length=0 (you must enter a length).

Dynamic Length

Dynamic refers to the pole or pendant changing length based on the mounting height of the luminaire. The base of a Dynamic pole is attached to the Z coordinate specified in the luminaire definition (Attach to Z=). By default, this Z coordinate is 0.

Example: If you specify a Dynamic pole attached to Z=0 AND you specify a luminaire mounting height of 30, your pole length will be 30 (30-0). If you specify a Dynamic pole attached to Z=10 AND a luminaire mounting height of 30, your pole length will be 20 (30-10).

Should be elect to use a Dynamic setting for a Pendant, be sure to set the Attach to Z= cell to the ceiling height where the pendant mounts. The default is zero which would draw the pendant to the floor, obviously incorrect!

Static is the default Pendant behavior.

 

Static Length

Static refers to the Pendant or Pole length remaining constant regardless of the mounting height of the luminaire. Static length is the default behavior of Pendants, (length =0).

For Pendants enter a length for the Pendant (it is not zero). This would be the length from the ceiling to the luminaire insertion point.

For Poles, use a Static designation when the base of the pole changes in elevation but the relative pole length remains the same (as on a hill).

Example: If you specify a Static pole length of 10 AND you specify a mounting height of 30, your pole base would be located at Z=20 (30-10).  If you  specified another luminaire with a mounting height of 25, your pole base would be located at 15 (25-10).
