WARNINGS W arning symbols and meanings In this User Manual warning symbols are used. These are intended to alert you to the potent ial hazards to personnel which are associated with the equipment described, in all aspects of use, including handling, installation, operation and maintenance.
READER’S NOTE S GENERAL This manual describes the Installation, Maintenance and S p ares of the ServoT ube 38 linear motor . ASSOCIATED PUBLICATIONS The following publications are associated with the ServoT ube 38 User Manual.
Page ( vi) Prelims ServoTube 38 Installation Guide.
SERVOTUBE 38 ACTUATOR The ServoT ube 38 Actuator is an optimal solution for industrial position control. Faster than a ballscrew with the clean reliability of a linear motor , the ServoT ube 38 is a cost-effective alternative to air cylinders in applications requiring greater flexibility and control.
The tubular motor has superior thermal ef ficiency , radiating heat uniformly . High duty cycles are possible without the need for forced-air or water cooling. Amplifiers ServoT ube 38 is complemented by a range of matched, self-tuning servo-amplifiers and indexers complete with plug-and-play cabling.
Chapter 2 Installation UNPACKING • Check packaging for signs of damage. • Metal surfaces may be hot or below 0 o C following prolonged storage. • Remove packaging. Do not discard. In the event of items requiring return, it is recommended that the original packaging be used.
Mechanical - XT A The outline drawing of the XT A is shown in Figure 2.1. It comprises the forcer with an integrated plastic sleeve bearing and the thrust rod. The integrated bearing act s as a guide for the moving thrust rod. It is not intended to wit hstand side loading.

Electrical All electrical connections to the XT A and XTB are made via two cables, see Figure 2.3. One carries power to the forcer and the other carries signals from the position sensor . These cables are supplied either pre-terminated for a specific drive or with flying leads.
Chapter 3 Maintenance XT A The XT A is low maintenance and as such requires only minimal periodic inspection. The integral bearing is dry running, requiring no lubrication. Periodically: • Check that the thrust rod can move freely over the entire stroke.
• Loosen the two fixings on the cable clamp. • Pull the cable out through the cable gland. Replacement Re-fitting is the reverse of the removal procedure. • Feed the new cable(s) through the cable gland. • Connect the cable(s) including the earth lead.

Appendix A Glossary of Terms & Abbreviations GLOSSARY OF TERMS TERM DESCRIPTION O F TERM Peak force Peak force is the force produc ed when the peak current is applied to the motor. It is the product of Force constant (N/A pk ) and Peak current (A pk ).
TERM DESCRIPTION O F TERM Electrical time constant Electrical time constant is the time taken f or a step current input to t he motor to reach 63.2% of its value. Continuous working voltage Continuous working voltage is the maximum allowable continuous voltage between any two motor phases or between any motor phase and the motor safety earth.
Appendix B Troubleshooting TROUBLESHOOTING CHART Check to see if the problem you are experiencing is listed in the chart below . If the problem cannot be solved with reference to this chart, contact the customer services dep artment. Fault Possible cause A ction Forcer/thrust rod f ails to move and produces no force.

POSITION SENSOR The position sensor outputs analogue, dif ferential sine and cosine signals for providing position feedback. Figure C. 1 shows the relationships between motor phase back EMF and position sensor output s for one direction of motion (as shown by arrows in Figures C.
MOTOR OVER TEMPERATURE SENSOR It is strongly recommended that the motor over-temperat ure sensor is connected to the drive amplifier or servo controller at all times in order to reduce the risk of damage to the motor due to ex cessive temperatures.

Un punto importante, dopo l’acquisto del dispositivo (o anche prima di acquisto) è quello di leggere il manuale. Dobbiamo farlo per diversi motivi semplici:
Se non hai ancora comprato il Motion Actuator è un buon momento per familiarizzare con i dati di base del prodotto. Prime consultare le pagine iniziali del manuale d’uso, che si trova al di sopra. Dovresti trovare lì i dati tecnici più importanti del Motion Actuator - in questo modo è possibile verificare se l’apparecchio soddisfa le tue esigenze. Esplorando le pagine segenti del manuali d’uso Motion Actuator imparerai tutte le caratteristiche del prodotto e le informazioni sul suo funzionamento. Le informazioni sul Motion Actuator ti aiuteranno sicuramente a prendere una decisione relativa all’acquisto.
In una situazione in cui hai già il Motion Actuator, ma non hai ancora letto il manuale d’uso, dovresti farlo per le ragioni sopra descritte. Saprai quindi se hai correttamente usato le funzioni disponibili, e se hai commesso errori che possono ridurre la durata di vita del Motion Actuator.
Tuttavia, uno dei ruoli più importanti per l’utente svolti dal manuale d’uso è quello di aiutare a risolvere i problemi con il Motion Actuator. Quasi sempre, ci troverai Troubleshooting, cioè i guasti più frequenti e malfunzionamenti del dispositivo Motion Actuator insieme con le istruzioni su come risolverli. Anche se non si riesci a risolvere il problema, il manuale d’uso ti mostrerà il percorso di ulteriori procedimenti – il contatto con il centro servizio clienti o il servizio più vicino.
