LAT3 series

Product catalog summary

Overview: The document provides technical specifications and operational guidelines for the LAT3 series of linear motors, designed for precise positioning and pushing applications. These systems integrate a linear motor, linear guide, and displacement sensor into a single unit.

Specifications:

Stroke options: 10 mm, 20 mm, 30 mm
Positioning repeatability: ±5 µm for LAT3F models, ±90 µm for LAT3 models
Maximum pushing force: 6 N
Weight: Ranges from 4.6 oz (130 g) to 8.8 oz (250 g) depending on the model
Maximum speed: 400 mm/s
Load mass: Up to 500 g vertically, 100 g horizontally

Features:

Easy programming with three parameters: positioning time, target position, and load mass
Two body mounting options: bottom and top
Integrated cable connector that does not protrude above the actuator

Operating Principles:

The system uses a linear motor where a permanent magnet and coil generate thrust force, allowing the table to move in both directions based on current direction.
Positioning and pushing operations are controlled through a setup process involving the entry of specific parameters into the controller.

Model Selection:

Selection is based on required positioning repeatability, stroke, and load mass.
Graphs and tables are provided to determine the shortest positioning time and allowable load mass.
Considerations include mounting orientation, angle, and overhang.

Recommendations:

Ensure the duty ratio is managed to prevent overheating of the Card Motor.
Verify that the applied load and pushing force do not exceed specified limits.

Conclusion: The LAT3 series offers a versatile solution for applications requiring precise linear motion, with easy setup and a range of models to suit different operational needs.

Specifications and Model Selection: The document outlines the specifications for the Series LAT3 Card Motor, including details on sensor resolution, stroke lengths, actuator cable lengths, and controller options. The thrust setting values are specified for minimum, continuous, and instantaneous maximum thrust for each model. The operating conditions include horizontal table mounting and specific pushing directions.

Ordering Information: The document provides a detailed guide on how to order the Series LAT3, specifying options for sensor resolution, stroke, actuator cable length, controller type, and I/O cable length. It also notes that certain options like controllers and cables can be included in the order, while others must be ordered separately.

System Construction and Accessories: The system construction includes components such as multi-counters, controller setup kits, power supply cables, and actuator cables. Accessories supplied with the controller include power supply plugs and counter plugs. Separately sold products include multi-counters and controller setup kits.

Controller Specifications: The LATC4 controller specifications include power supply voltage, current consumption, power consumption, input and output signals, and operating conditions. The controller can be mounted using screws or a DIN rail, and it features natural air-cooling and LED indicators for power and alarms.

Mounting and Wiring: The document provides detailed instructions for mounting the controller, including dimensions and wiring examples for both NPN and PNP output circuits. It emphasizes the importance of correct wiring and the use of appropriate cables for connecting power supplies and I/O devices.

Positioning Operations: The document describes two methods for setting step data in the Card Motor controller: the Takt Time Entry Method and the Speed Entry Method. Each method involves calculating positioning distances and times based on load mass and desired speed or positioning time. The document provides equations for calculating acceleration, deceleration, and positioning times.

Operation Modes: The Card Motor controller supports two main operation modes: transporting a workpiece to a specific position and applying force to a workpiece. The positioning operation involves automatic calculation of acceleration and deceleration based on set positioning time or speed, while the pushing operation requires setting the target position at least 1 mm away from the contact point to avoid damage.

Return to Home Position: There are three methods for returning to the home position: mechanical end stopper, external jig, and sensor home. Each method has specific procedures and considerations for setting the home position accurately.

Signal Timing and Wiring: The document details the signal timing for various operations, including positioning and pushing, and provides wiring diagrams for connecting the controller, actuator, and multi-counter. It emphasizes maintaining a minimum interval between input signals.

Safety and Handling Precautions: The document warns against using the Card Motor outside specified limits, applying excessive force, and operating in environments with strong magnetic fields. It also advises on handling the product safely to prevent injuries and equipment damage.

Design and Selection Considerations: Users are advised to consider potential movements during emergencies and ensure the Card Motor is used within its specifications to avoid reducing its lifespan and accuracy.

Mounting Instructions: Detailed instructions are provided for mounting the Card Motor, including recommended torque values and considerations for maintaining flatness and avoiding damage to the guide rail and table.

Operating Environment:

Avoid using products in areas with dust, metallic powder, or exposure to water, oil, or chemicals to prevent malfunctions.
Do not use in magnetic fields or environments with flammable, explosive, or corrosive substances.
Protect from strong light sources and heat radiation to prevent sensor malfunctions and overheating.
Ensure usage within specified temperature and humidity ranges.

Maintenance:

Regular maintenance and inspections are crucial to prevent malfunctions.
Conduct functional tests post-maintenance and ensure emergency stop functionality.
Do not disassemble or modify the product.
Ensure sufficient space for maintenance activities.

Grounding:

Always ground the Card Motor using a dedicated D-class grounding with resistance of 100 Ω or less.
Keep grounding points close to the actuator and minimize ground wire length.

Installation:

Mount the Card Motor on a base with good cooling performance to prevent overheating.
Use stainless steel screws with appropriate length and torque for mounting.
Avoid applying impact or excessive force to the Card Motor during installation.

Design/Selection Handling:

Use specified voltage to avoid malfunctions or damage.
Install an emergency stop circuit accessible to operators.
Implement a backup system to prevent damage from potential malfunctions.

Handling:

Avoid touching internal components to prevent electric shock.
Ensure safe movement of workpieces before powering the product.
Prevent static electricity from affecting the controller.

Wiring:

Turn off power before wiring and ensure proper connections to avoid malfunctions.
Separate digital I/O signal and power cables to prevent noise interference.

Power Supply:

Use low-noise power supplies and separate controller and I/O signal power supplies.
Take measures to prevent surges from lightning and use UL-certified power supplies.

Safety Instructions Overview: Before using SMC products, it is crucial to read the 'Handling Precautions for SMC Products' (M-E03-3). The responsibility for ensuring product compatibility with specific equipment lies with the designer or specifier, who must conduct necessary analyses and tests. Continuous review of product specifications is advised to prevent equipment failure.

Personnel and Operation: Only trained personnel should operate machinery and equipment. Incorrect handling can lead to unsafe conditions. Maintenance and assembly should be performed by experienced operators.

Service and Maintenance: Ensure safety before servicing or removing products. Confirm measures to prevent falling or runaway of driven objects. Implement safety measures and cut power before removal. Prevent unexpected operation before restarting equipment.

Special Conditions: Contact SMC for special safety considerations if using products in conditions outside specifications, such as outdoors, in direct sunlight, or in critical applications like atomic energy or medical treatment.

Warranty and Compliance: The product is intended for peaceful use in manufacturing industries. The warranty period is 1 year in service or 1.5 years after delivery, excluding vacuum pads. Compliance with security laws is required for international transactions.

Hazard Levels: Safety instructions use labels 'Caution,' 'Warning,' and 'Danger' to indicate hazard levels. These must be followed alongside international standards like ISO 4414 and IEC 60204-1.
