Chapter 1 Safety Considerations

Vertical or Incline Installation

A linear motor driven system mounted vertically or on an incline will not maintain position when the power is removed. Under the influence of gravity the motion platform and its payload will fall to the low end of travel. Design engineers should allow for this by designing in controlled power down circuits or mechanical controls to prevent the linear motor driven system and its payload from being damaged when the power fails.
ATTENTION
Linear motors are capable of high accelerations, sudden and fast motion. Rockwell Automation is not responsible for misuse, or improper implementation of this equipment.
ATTENTION
Linear motor driven systems must have end of travel bumpers. They must be designed to take a large impact from uncontrolled motion. The payload must be secured to the system such that it will not sheer off in the event of an impact in excess of the bumper ratings.
ATTENTION
The Hall effect module contains an electrostatic discharge (ESD) sensitive devise. You are required to follow static-control precautions when you install, test, service, or repair this assembly. If you do not follow ESD control precautions, components can be damaged. If you are not familiar with static control precautions, refer to Guarding Against Electrostatic Damage, publication 8000-4.5.2
, or any other applicable ESD
awareness handbook.
BURN HAZARD
When the linear motors are running at their maximum rating the temperature of attached heat sink can reach 100 ºC (212 ºF).
SHOCK HAZARD
An assembled linear motor will generate power if the coil or magnet channel is moved. Un-terminated power cables present an electrical shock hazard. Never handle flying leads or touch power pins while moving the motor.
12 Publication LDL-UM001A-EN-P - March 2009
Safety Considerations Chapter 1

Operational Guidelines

Please read and follow the guidelines shown here to safely operate the linear motor created from the these linear motor component s .
ATTENTION
Observe maximum safe speed. Linear motors are capable of very high forces, accelerations, and speeds. The maximum obtainable acceleration and speed is based on the drive output (bus voltage and current settings). The allowable maximum speed is application specific and partly based on the linear motion mechanics supplied by others.
ATTENTION
Moving parts can cause injury. Before operating the linear motor, make sure all components are secure and magnet mounting hardware is below magnet surface. Remove all unused parts from the motor travel assembly to prevent them from jamming in the motor air gap and damaging the coil or flying off and causing bodily injury.
IMPORTANT
You are responsible for making sure the servo control system safely controls the linear motor with regards to maximum safe force, acceleration, and speed, including runaway conditions.
ATTENTION
ATTENTION
A runaway condition can be caused by incorrect motor, hall effect, and position feedback wiring resulting in violent uncontrolled motion.
Keep away from the line of motor travel at all times. Always have bumpers in place and securely fastened before applying power to your linear motor.
High Voltage can kill. Do not operate with exposed wires. Do not go near electrically live parts.
Publication LDL-UM001A-EN-P - March 2009 13
Chapter 1 Safety Considerations
WARNING
Large Position Error Tolerances, such as those calculated by the Auto Tune function in RSLogix 5000 programming software, or when configuring a new axis with RSLogix 5000 software, can lead to undetected and repetitive high energy impacts against axis end stops if proper precautions are not in place. These tolerances can also lead to undetected and repetitive high energy impacts against unexpected obstructions. Such impacts can lead to equipment damage and/or serious injury.

Maintenance

Motor Storage

Publication LDL-UM001A-EN-P - March 2009 19
Linear motors require no maintenance when operated in a relatively clean environments. For operation in harsh and dirty environments, minimal cleaning is recommended every 6 months.
Clean the metallic debris and other contaminants from the air gap. Use a strip of masking tape to effectively remove the metal debris. Apply a strip of tape in the magnet channel and then remove it.
Motor storage area should be clean, dry, vibration free, and have a relatively constant temperature. If a motor is stored on equipment, it should be protected from the weather. All motor surfaces subject to corrosion should be protected by applying a corrosion resistant coating.

Introduction

Unpacking and Inspection

The following section shows you how to safely unpack and install your linear motor components.
Topic Page
Unpacking and Inspection 21 Installing the Linear Motor Components 22 Mount the Magnet Channel 22 Mount the Motor Coil 25
Inspect motor assemblies for damage that may have occurred in shipment. Any damage or suspected damage should be immediately documented. Claims for damage due to shipment are usually made against the transportation company. Contact Rockwell Automation immediately for further advise.
ATTENTION
Linear motors contain powerful permanent magnets which require extreme caution during handling. When handing multiple magnet channels do not allow the channels to come in contact with each other. Do not disassemble the magnet channels. The forces between channels are very powerful and can cause bodily injury. Persons with pacemakers or Automatic Implantable Cardioverter Defibrillator (AICD) should maintain a minimum distance of 0.33 m (1 ft) from magnet assemblies. Additionally, unless absolutely unavoidable, a minimum distance of 1.5 m (5 ft) feet must be maintained between magnet assemblies and other magnetic or ferrous composite materials. Use only non-metallic instrumentation when verifying assembly dimension prior to installation
• Compare the purchase order with the packing slip.
• Check the quantity of magnet channels received matches your
job requirements.
• Identify the options that came with your linear motor.
• Inspect the assemblies and confirm the presence of specified
options.

Chapter 3 Installing the LDL-Series Linear Motor

Installing the Linear Motor Components

Use the following procedures to install the magnet channel and the motor coil.
Required Tools:
• Aluminum straight edge
• Non-magnetic M4 or M5 hex wrench
• Magnet channel alignment tool
IMPORTANT
TIP
The alignment tool is shipped attached to the cables next to the Hall effect module. Remove before operating the linear motor.
Non-magnetic tools and hardware made of beryllium copper, 300 series stainless steel, and others should be used. If not available, proceed carefully since magnetic and ferrous items will be attracted to the magnet channel.
Mount the Magnet Channel
1. Select screw size and quantity.
The size of the Socket Head Cap Screw (SHCS) depends on mounting configuration. The diagram shows three ways you can mount your linear motor components. Mounting configuration B de-rates the motor continuous force by 10%. See Appendix A starting on page 66
Mounting Configuration
A M6 16.0 (11.8) 10.8 (8.0) B and C M5 9.5 (7.0) 6.36 (4.7)
