  • Page 4: Safety

    Equipment should be designed and utilized to prevent personnel from coming in contact with moving parts that could potentially cause injury. Read the Moog Linear Motor User’s Manual which applies to the motor you are using before attempting to operate this device.
  • Page 5 A NOTE identifies information that is critical for successful application and understanding of the product. Follow all warnings and cautions listed in this manual and in the applicable Moog Linear Motor User’s Manual when working with Moog Components Group High Force Linear Motors.
  • Page 6 Linear Motor shaft necessitating repair by Moog. CAUTION: The Moog Linear Position Sensor is not designed to accommodate shock loads greater than 100 G. Ensure that the shaft does not slam into either end stop.

  • Page 7: Scope

    Scope: This manual provides information for the installation of Linear Encoder Options LCA, LCB, LCC, LCD and LCE which are available with the Moog 4020/5020 Linear Motors. For all other aspects of Linear Motor installation, please refer to the appropriate user’s manual.

  • Page 8: Introduction

    The Linear Encoder Option is not designed to be removed, aligned, adjusted, disassembled or installed by the user. Typical Servo System with Moog Motor: Moog Motor with Linear Scale Option LCX Fig 4-1 Options LCX provide Integral Motor Position Sensing as part of the Linear Motor System.

  • Page 9: Installation Sequence

    4.1. Installation Sequence: Use the following sequence when installing a Moog linear motor the Linear Sensor Option. Those steps in bold apply specifically to this Linear Encoder Installation manual. 1. Read the applicable motor installation manual and observe all warnings, cautions, and notes in Sections 1 and 2 of that manual.

  • Page 10: Information For Drive Or Controller Setup

    The motor part number specifies the Linear Encoder Option: CLD4020D06-LCX-T-CV LCX is either LCA, LCB, LCC, LCD or LCE. Linear Encoder options A through E provide different resolutions, signal types, and compatibility. The Interface Control Drawing for the Linear Encoder option contains the relevant specifications.

  • Page 11: Mechanical Mounting Notes

    Mechanical Mounting Notes: 6.1. Encoder Alignment: The Linear Encoder Option provides Position Feedback, Commutation data, Indexing and Home switch functions required to control the Motor. With the encoder option, encoder and Hall device “heads” are mounted together on one end of the motor shaft. The heads move with the shaft and read positional and commutation data from separate, stationary tracks mounted to the encoder rail.

  • Page 12: Dual-Face Mounting

    For information on Dual-Face Mounting please refer to the appropriate Moog user’s manual. 6.3. End-Stops: Two End Stops are provided on the Moog Motor. The internal End Stop is not to be removed by the user. Fig 6-2 LCX Option provides an internal End Stop.
  • Page 13 WARNING: Do not step onto or apply lateral Loads onto the Linear Position Sensor Housing. CAUTION: The Moog Linear Position Sensor is not designed to accommodate shaft rotation. An external torque applied to the shaft will cause Linear Position Sensor misalignment leading to loss of position control and phasing.

  • Page 14: Encoder Cable Connections

    Modular Cables. Wiring can be greatly simplified if a Drive or Amplifier is used for which a Moog standard cable already exists. See Moog product literature to select a cable on the basis of Drive model and required cable length.

  • Page 15: Wiring The Linear Encoder To The Drive With The Pigtail Cable

    7.2. Wiring the Linear Encoder to the Drive with the Pigtail Cable: If you cannot use a modular cable, connect the drive using the following “pigtail” cable: FSC-EC-XX where XX = 02, 10 or 25, corresponds to cable length in feet. Figure 7-2 Pigtail Cable provides termination to most compatible Drives.

  • Page 16: Pigtail Cable Signal Descriptions

    7.2.2. Pigtail cable signal descriptions: In addition to sensor power, five general types of signals are accessed by the Linear Encoder connector: Position, Hall, Fault / Signal Quality, Reference Mark and Index. Additional, auxiliary pins are reserved for future use. Identify and wire the Encoder Power and signals for Position, Commutation, Encoder Fault, Reference Mark and Index functions per Figure 7-4 and the following signal descriptions.

  • Page 17: Digital Quadrature Incremental Signals A And B

    Differential mode “Sin/Cos” inputs per Figure 7-4. 7.2.2.4. Encoder Misalignment Fault Alarm E: Encoder options LCA, LCB, LCC and LCD provide a HIGH state on TTL level Differential alarm outputs E when the optical encoder signal falls below 45% nominal range. 7.2.2.5.

  • Page 18: Reference Mark (Z, Vo) And Limit Switch (Vq) Signals

    A Differential Mode TTL Level (0-5V) voltage signal, active “HIGH” provides an accurate absolute position reference to designate the rated Mid stroke shaft position. (The Reference Mark is designated “Z” in options LCA, LCB, LCC and LCD and “Vo” in option LCE).

  • Page 19: Commutation (Hall Sensor) Connections

    The Reference Mark is Synchronous with both Digital and Analog Quadrature signal phase. Repeatability of the Reference mark is limited in Digital and Analog sensors by one quadrature Line Count or by +0 / -18 degrees of Sin/Cos signal phase respectively.

  • Page 20: Inner And Outer Shields

    Grounding and Shielding of the Drive cables are also important for safety and for proper sensor electrical noise immunity. For more detail in system Grounding and Shielding, please see the Moog Linear Motor User’s Manual. CAUTION: Poor ground or shield connections or wiring can cause unpredictable motion, and could damage the motor, control system or machine.
