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. Four models The ServoT ube 38 Actuator incorpora[...]

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. Amplifiers interface easily to PLCs and feature[...]

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. • Ensure that the delivery note correctly reflects your order and t[...]

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. If side loading is expected then it is advised t hat an external bearing is [...]

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. Where they are pre-terminated, simpl y plug the cables into the relevan[...]

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. • Clean any accumulated debris from the thrust rod surface (ferrous material, in particular[...]

• 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. • Tighten the cable retaining clamp. • Take care not to damage the sealing gasket on [...]

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 ). The motor is not mov ing, there is no forced cooling and no additional heat -sinking. The dur[...]

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. Pole [...]

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.1 and C.2). It should be noted that +SIN or -SIN is always in phase wi[...]

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. Protection is provided by three, positive tem perature coefficient (PT C) thermistors embedded in the[...]
