Page 11: Special Safety Instructions For The Al38Xx
Safety Special safety instructions for the AL38xx The safety instructions are designed to avert danger and must be followed during installation, commissioning, production, troubleshooting, maintenance and trial or test assemblies. The linear servomotors from the AL3xxx series are not capable of running independently and are always installed into a machine or system. - Page 12 Safety NOTE Damage to the magnets at higher temperatures The magnets should never be exposed to temperatures above 70° C. They can become demagnetized at higher temperatures. CAUTION Magnetic attractive forces can lead to damage • The magnetic plates exercise a powerful attractive force on any soft-magnetic materials such as iron. These forces are more than the hand can manage.

Page 15: Technical Description
Technical description Technical description Design of the motors The linear servomotors from the AL38xx series are ironless three-phase motors for high-quality servo applications. In conjunction with our digital servo drive, they are particularly suitable for positioning tasks in the semiconductor industry with demanding requirements in terms of synchronism and precision. The motors from the AL38xx series are intended to be operated exclusively by the digital servo drive with speed and torque control. -

Page 17: Standard Features
Technical description Standard features The ironless linear servomotors of the AL38xx series from Beckhoff are not self-contained systems. It includes various components such as a coil unit and magnet yokes and must be integrated into a complete machine concept or a complete working unit. The size and shape of the carrier frame, the design of the carriage, the type of rail and type of bearings, and the kind of buffer used depend on the application. -
Page 18: Additional Equipment
Servo drive and feedback system The following components are required for the construction of a complete linear axis and its operation: • Servo drive, e.g.: AX5xxx from Beckhoff Automation GmbH & Co. KG. • Graduated rule and linear displacement transducer •... -
Page 19: Mechanical Installation
Mechanical installation Mechanical installation Specification of the mounting surfaces The mounting surfaces for the magnet yokes and the coil unit must be extremely even, in order to prevent bending forces. • Evenness of the mounting surface for the coil unit: ≤ 0.1 mm •... -
Page 20: Installation Sequence
Mechanical installation Installation sequence WARNING Damage due to uncontrolled magnetic attractive forces The sequence specified in this introduction for the installation must be followed. Deviation from the se- quence may result in dangerous situations and damage through magnetic forces. Complete the installation of the machine bed, before installing the linear motor components. Mount and align the rails and the graduated rule on the machine bed. -
Page 21: Assembling The Coil Unit
Mechanical installation Assembling the coil unit NOTE Damage due to contamination The mounting surface must always be free from contamination. Particles with a size of more than 0.1 mm can result in incorrect configuration and damage to the linear motor. Mounting of the coil unit on the clean mounting surface of the carriage is not hindered by attractive forces! An axis reference for the coil unit (CR) is achieved as follows: •... -
Page 22: Electrical Installation
Connection of motors with preassembled ca- bles • Use only cables approved by Beckhoff for the operation of the AL38xx. • Route the power and encoder cables as separately as possible from one another (separation > 20 cm). -
Page 23: Connection Of Motors With Flying Wires
Beckhoff offers preassembled motor and feedback cables for safe, faster and flawless installation of the motors. Beckhoff cables have been tested with regard to the materials, shielding and connectors used. They ensure proper functioning and compliance with statutory regulations such as EMC, UL etc. The use of other cables may lead to unexpected interference and invalidate the warranty. -

Page 26: Calculation Of The Brake Resistor
Electrical installation Calculation of the brake resistor During the braking procedure of the linear axis, energy is fed back into the servo drive. During the design the regenerative power must be calculated in order to select a brake resistor if necessary. To do this the peak and continuous power must be calculated. -
Page 27: Ntc Specification
All linear servomotors from Beckhoff are wired and connected in exactly the same way, so that a single test is sufficient in order to determine the polarity of a motor/graduated rule combination. If more than one axis is being constructed in a similar way, the polarity will be identical. -
