LEFB, LEFG-BS series

Product catalog summary
Overview: The document provides comprehensive specifications and guidelines for the Ball Screw Drive Series LEFS and Belt Drive Series LEFB electric actuators, designed for precise positioning and high-speed transfer applications. It also covers step motors and servo motors, focusing on 24 VDC models, and includes information on controllers, drivers, and electric actuators.
Specifications:
  • Ball Screw Drive (LEFS): Available in sizes 16, 25, 32, 40 with a maximum stroke of 2000 mm and speed of 2000 mm/s. Positioning repeatability is ±0.02 mm. Supports step motor (Servo/24 VDC) and AC servo motor.
  • Belt Drive (LEFB): Available in sizes 16, 25, 32 with a maximum stroke of 3000 mm and speed of 2000 mm/s. Not suitable for vertical applications.
Motor and Mounting Options: Motors include step motor (Servo/24 VDC), servo motor (24 VDC), and AC servo motor. Motor mounting options include parallel and bottom mounting types.
Controller and Encoder Types: Controllers include Series LECSB, LECSC, LECSS for absolute encoders, and Series LECSA for incremental encoders. Step data input types include Series LECP6/LECA6 and programless type Series LECP1.
Performance Features: High-speed transfer capability with maximum acceleration/deceleration of 20000 mm/s². Clean room specifications are available for certain models. Equipped with seal bands to prevent grease splashing and entry of foreign matter.
Application Examples: Precise positioning of workpieces, load and unload transfer of workpieces, and pick and place operations.
Additional Features: Built-in vacuum piping for minimizing external particle generation. Support guide for workpieces with significant overhang. Easy mounting and reduced installation labor due to compact design.
Control and Operation: Easy mode for simple settings and normal mode for detailed settings available. Fieldbus-compatible gateway unit for connecting up to 12 controllers. Programless operation with Series LECP1 for easy setup without a PC or teaching box.
Specifications and Operating Limits: The document emphasizes not exceeding operating limits to avoid noise, degraded accuracy, and shortened product life. Actuators should not be used in applications with excessive external force or impact.
Selection and Handling Warnings: Warnings include not increasing speed beyond the operating limit and ensuring the actuator is not subjected to excessive external forces. Proper mounting is crucial to avoid damage.
Maintenance Guidelines: Regular maintenance is advised, including visual checks for loose screws, dirt, and cable joint issues, and internal checks for lubricant condition and mechanical play.
Model Specifications: Detailed specifications for different models (LEFS25, LEFS32, LEFS40) are provided, including stroke lengths, work load capacities, maximum speeds, and acceleration limits.
Installation and Mounting Instructions: Instructions for mounting the actuator include ensuring the correct height for the body mounting reference plane and avoiding interference with surrounding workpieces.
Component Parts: The document lists various components of the LEFB32/40SS electric actuator, including materials and notes on coatings and anodizing.
Specifications: Detailed dimensions for different stroke lengths of the belt drive series LEFB are provided, including measurements for motor top and bottom mounting types.
Procedures and Recommendations: Recommendations for mounting the actuator include setting the height of the opposite surface or pin to be 3 mm or more due to R chamfering, with a recommended height of 5 mm.
Standards and Norms: The document outlines the use of absolute and incremental encoders with specific resolutions, and mentions compatibility with Mitsubishi Electric’s servo system controller network.
Recommandations: The document suggests using CC-Link communication for connecting up to 32 drivers and SSCNET III for up to 16 drivers, emphasizing the importance of high-speed optical communication for efficient operation.
Key Data from Tables: The tables provide detailed dimensions for various stroke lengths, specifying parameters such as length (L), width (A), and other critical measurements for different configurations of the LEFB series actuators.
Overview: This document provides technical specifications, wiring examples, and safety precautions for the Mitsubishi Electric AC Servo Motor Driver Series LECS. It includes detailed instructions on installation, handling, and operation to ensure safe and efficient use.
Specifications: The document outlines the voltage requirements, torque limits, and control signal wiring for the LECS series. It specifies the use of a 24 VDC power supply and details the connections for various components such as pulse detectors and control signals.
Wiring and Connections: Detailed wiring examples are provided for connecting the servo motor driver to a positioning unit, emphasizing the importance of proper grounding and the use of protective earth (PE) terminals to prevent electric shock.
Safety Precautions: The document highlights critical safety warnings, including the need to use specified voltages, install emergency stop circuits, and avoid operating the equipment with wet hands.
Handling and Maintenance: Instructions are given for safe handling, including avoiding static electricity, ensuring proper installation on fireproof materials, and maintaining a safe distance from heat sources.
Mounting Instructions: The servo motor driver should be mounted on a vertical wall with a flat surface to prevent malfunctions.
Grounding: Proper grounding is essential for safety, and the document provides instructions for connecting the actuator's copper wire to the driver’s protective earth terminal.
