WARNINGS
Warning symbols and meanings
In this User Manual warning symbols are used. These are intended to alert you to the potential hazards to personnel
which are associated with the equipment described, in all aspects of use, including handling, installation, operation and
maintenance.
Heart pacemakers. Personnel fitted with pacemakers must not handle or work on this equipment.
Strong magnets. The thrust rod contains powerful magnets and will strongly attract ferrous objects.
Damage can occur to computer disks and credit cards.
Electric shock. Potentially lethal voltages may be present during the commissioning and servicing of
this equipment. Isolate and disconnect all sources of electrical supply before working on the
equipment. Particular care needs to be taken when working on or around motor phase connections.
Hot surface. Surface temperatures of up to 80 °C can be present during the commissioning and
servicing of this equipment. Allow the forcer and thrust rod to cool before working on the equipment.
Heavy object. May need two people to lift.
Crush hazard. The forcer may move unexpectedly. Always isolate all sources of electrical supply
before working on the equipment.
General hazard. Follow the advice given.
Electrical safety
This equipment must be earthed using the green/yellow conductor.
EMC precautions
This equipment is intended for use in a light industrial environment. It is recommended that the following precautions be
observed during installation:
Keep all cable lengths to a minimum.
•
Provide as much physical separation as possible between power and signal cables. In particular, avoid long,
•
parallel runs of cables.
Maintain screen continuity throughout the cable run.
•
Use 360 degree screen terminations where possible. “Pig-tail” terminations are not recommended.
•
It is the responsibility of the User to ensure compliance with any local electrical and EMC regulations in force at
•
the time of installation.

Product Overview
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.
Four models
The ServoTube 38 Actuator incorporates an IP67 rated
forcer and a sealed stainless steel thrust rod enclosing
rare-earth magnets. Four models deliver a continuous
force range of 137-276 N (31-62 lb) with peak forces up
to 1860N (418 lb). Nine stroke lengths are available
from 33- 318 mm
The patented magnetic design of ServoTube 38
generates 25 micron (0.98 mil) repeatability and 400
micron (16 mil) accuracy from a non-contact, integral
position sensor. No external encoder is required.
Position output is industry standard 1V pk-pk sin/cos
signals.
model number and the system comes up tuned and
ready to run. Clear diagnostics make system
commissioning easy. Fill in the blanks to define position,
velocity and acceleration.
SERVOTUBE 38
ServoTube 38 delivers the speed of a belt-drive
system with the clean reliability of a linear motor at
a price unprecedented in the industry. Familiar
form factor, integral position feedback and large air
gap make installation simple.
The ServoTube 38 motor components comprise an
IP67 rated forcer and a sealed stainless steel thrust rod
enclosing rare-earth magnets. Four models deliver a
continuous force range of 137-276 N (31-62 lb) with
peak forces up to 1860 N (418 lb). A range of Thrust
Rods are available for travel lengths up to 1362 mm.

Maintenance free
The XTA has an internal dry bearing which provides a
clean, quiet, maintenance free performance. Life
expectancy far exceeds typical ballscrew solutions. The
ServoTube 38 Actuator is ideal for push/pull/lift material
handling, packaging and automated assembly
applications. ServoTube 38 accepts a range of industry
standard accessories for simple mechanical integration.
Plug and Play
Flexible mid-stroke position control is simple with Xenus
- a matched, self-tuning indexer complete with plugand-play cabling. Simply select your ServoTube 38

signals.
Easy Integration
ServoTube 38 is an ideal OEM solution for easy
integration into pick-and-place gantries and general
purpose material handling machines. The load is
mounted directly to the Forcer typically supported by a
single bearing rail. The Thrust Rod is mounted at both
ends, similar to a ballscrew. A large air gap reduces
alignment constraints.

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. Amplifiers interface easily to
PLCs and feature CANopen network connectivity for
distributed control applications.

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. If side loading is expected then it is advised that an external bearing is fitted.
The XTA forcer can be mounted by two methods.
• Using the T -slots in the top of the forcer.
• Using M6 fixings (4 off) on the end flange.
IMPORTANT
When using the end flange fixing method, the fixings and mounting plate must be of a non- ferrous material
such as aluminum, stainless steel, and plastic for example.
Dimensional details for both are given in Figure 2.1.
The recommended tightening torque for the fixings are:
M6 end flange 9 Nm M6 T-nut 10 Nm (both non lubricated i.e. no thread lock)
The thrust rod has optional male and female threaded connections at each end. These are intended to interface to a
number of standard accessories. The thrust rod has an external circlip at each end to restrain the thrust rod within the
forcer. These are not intended as "hard stops" to prevent over-travel and it is the responsibility of the User to prevent the
thrust rod from being ejected from the forcer.
