Page 7: Chapter 1 Product Overview
ServoTube 38 Installation Guide SERVOTUBE 38 ACTUATOR The ServoTube 38 Actuator is an optimal solution for industrial position control. Faster than a ballscrew with the clean reliability of a linear motor, the ServoTube 38 is a cost-effective alternative to air cylinders in applications requiring greater flexibility and control. - Page 8 Chapter 1 ServoTube 38 Installation Guide Overview The tubular motor has superior thermal efficiency, radiating heat uniformly. High duty cycles are possible without the need for forced-air or water cooling. Amplifiers ServoTube 38 is complemented by a range of matched, self-tuning servo-amplifiers and indexers complete with plug-and-play cabling.

ServoTube 38 Installation Guide UNPACKING • Check packaging for signs of damage. • Metal surfaces may be hot or below 0 • Remove packaging. Do not discard. In the event of items requiring return, it is recommended that the original packaging be used. - Page 10 Chapter 2 Installation Mechanical - XTA The outline drawing of the XTA is shown in Figure 2.1. It comprises the forcer with an integrated plastic sleeve bearing and the thrust rod. The integrated bearing acts as a guide for the moving thrust rod. It is not intended to withstand side loading.

- Page 14 Chapter 2 Installation Electrical All electrical connections to the XTA 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.

ServoTube 38 Installation Guide The XTA 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. •... - Page 16 Chapter 3 Maintenance • 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.

Page 21: Appendix A Glossary Of Terms & Abbreviations
ServoTube 38 Installation Guide Glossary of Terms & Abbreviations TERM DESCRIPTION OF TERM Peak force Peak force is the force produced when the peak current is applied to the motor. It is the product of Force constant (N/A The motor is not moving, there is no forced cooling and no additional heat-sinking. The duration of the peak force is thermally limited and is therefore only allowable for a period of 1 second. - Page 22 Appendices TERM DESCRIPTION OF TERM Electrical time Electrical time constant is the time taken for a step current input to the motor to reach 63.2% of its constant value. Continuous Continuous working voltage is the maximum allowable continuous voltage between any two motor working voltage phases or between any motor phase and the motor safety earth.

Figures C.1 and C.2). It should be noted that +SIN or -SIN is always in phase with motor phase U. For the motion shown, -SIN is in phase with motor phase U. For motion in the opposing direction +SIN is in phase with motor phase U. - Page 28 Appendices MOTOR OVER TEMPERATURE SENSOR It is strongly recommended that the motor over-temperature 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 excessive temperatures. Protection is provided by three, positive temperature coefficient (PTC) thermistors embedded in the motor phases.
