GantryFeedbackSeparation Parameter

Default Value: 0.0

Minimum Value: 0.0

Maximum Value: None

Units: distance

Type: float

The GantryFeedbackSeparation parameter defines Decoupling Control behavior of a gantry. For a gantry built from linear devices, it specifies a physical separation distance between the gantry spars. For a gantry built from rotary devices, this value is unity when the rotary units are radians. The table that follows supplies information to help you set the GantryFeedbackSeparation parameter.

Logical Axis Spar Device Type Mechanical Design GantryFeedbackSeparation Value
R Linear Rigid

Distance between the spar feedback devices in the same units as the R axis position.

R Linear Flexible

Distance between the flexible rotary joints in the same units as the R axis position.

R Rotary All

Value depends on the R rotary units:

  • radians: 1
  • milliradians: 1,000
  • microradians: 1,000,000
  • degrees: 180 / π
Theta All All 0
