Factory Installed Options:

Position Feedback Option
  • PF1: Off-Axis Absolute Encoder
    • Standard absolute feedback with Encoder
  • PF3: High Accuracy, ±0.005 degrees native read-out accuracy for most positioners
    • Replaces standard absolute feedback with center-drive high accuracy absolute encoder Options are available, to further enhance the native accuracy using error correction techniques. See Enhanced Accuracy Options brochure for additional information.

Limit Switch Options
  • LS0: No Limits, Continuous Rotation
  • LS1: Restricted Rotation up to ±200 degrees (adjustable)

RF Path Option
  • RJ Rotary Joint (Continuous Rotation)
    • Adds a single channel RF path inside the positioner supporting continuous, unrestricted rotation of the axis. The factory installed kit contains RF rotary joint and internal RF cabling.
  • RF Path (Restricted Rotation)
    • Adds a single channel RF path inside the positioner with restricted travel of the positioner up to a ±200 degree travel range. The factory installed kit contains internal RF cabling.

Electrical Path Option
  • CRU (Continuous Rotation for Upper-Axes)
    • Adds an electrical path inside the positioner supporting continuous unrestricted rotation of the upper motorized axis. The factory installed kit includes an internal electrical slip-ring assembly and internal wiring.
  • RRU (Restricted Rotation for Upper-Axes)
    • Adds an electrical path for upper motorized axes inside the positioner supporting restricted rotation up to ±200 degrees. The factory installed kit includes internal wiring.
  • CRT (Continuous Rotation for Thru-Contacts)
    • Adds an electrical path inside the positioner supporting continuous unrestricted rotation for dedicated thru-contacts. The factory installed kit contains an internal electrical slip-ring assembly and internal wiring.
  • RRT (Restricted Rotation for Thru-Contacts)
    • Adds an electrical path inside the positioner supporting restricted rotation up to ±200 degrees for dedicated thru-contacts. The factory installed kit contains an internal wiring harness, cap and chain protectors.

Convenience & Protection Options


Stow-Pin
 Adds manual stow-pin and mating receptacle to protect the positioner’s drive-train in susceptible environments such as high wind-gust exposure in outdoor environments and high-load pick-up mode applications. Includes electrical interlock circuit for disabling the servo system when stow-pin is inserted. Default position is zero (0) degrees. Alternate stow-pin angle locations are available upon request.

Riser
Adds a structural riser below the positioner for applications requiring accurate centering from a platform, outdoor silo applications, and various customer requested heights. Risers are designed to withstand the full capacity of the mated positioner and are tailored to your required height. Available features include access hatches, custom color, internal shelving, and external and internal ladders.
