1.1. Standard Features
A precision ground ballscrew and Linear Motion Guide (LMG) are standard features on all PRO115 stages.
The precision-ground, preloaded ballscrew ensures superior positioning resolution and accuracy while the
LMG bearing system provides stiffness, good load carrying capabilities, and continuous load support over
the entire range of travel. Other standard design features include an integral hardcover, side seals, and an air
purge to keep contamination out of the interior of the stage, and integral wipers on the ballscrew nut and bearing trucks to further reduce contamination. Optical limit switches and mechanical end stops, which protect
the carriage from over-travel, are also standard.

Overview
1.1.1. Optional Features
Available assembly options allow the PRO115 series stages to be configured for a variety of applications.
The standard motor for the PRO115 is the BMS60, which includes a 2500 line incremental squarewave
encoder and is available with an optional brake. A foldback option is available for use in space-constrained
applications. In addition, any motor with a NEMA 23 frame size and 6.35 mm (1/4”) or 9.53 mm (3/8”) shaft
can be mounted to the stage or to the foldback.
Figure 1-3:
PRO115 Stage Shown with Foldback Option
The stage table is available with the mounting holes and grid pattern in either English (-TTU) or Metric (-TTM)
dimensions. The –TT100 and –TT150 tabletop options provide quick mounting of an Aerotech ADRS-100 /
ACS-100LP or ADRS-150 / ACS-150LP in horizontal or vertical applications. The -TTAGR tabletop option provides quick mounting of an Aerotech AGR-50 with horizontal or vertical axis of rotation, or AGR-75 with vertical axis of rotation only. Optional wipers can be installed on all tabletops (or to the stage base for XY
applications) to prevent accumulation of debris on the hard cover.
PRO115 stages can easily be assembled in XY axis arrangements. The upper axis can be bolted directly to
the lower axis’ carriage, thereby reducing system height. Dedicated angle brackets are available to allow the
stages to be mated to form XZ or XYZ axis arrangements. Multi-axis combinations can be optionally aligned
to either 10 or 5-arc sec orthogonality. See Figure 1-4 and Figure 1-5 for examples of multi-axis arrangements.

Installation
Chapter 2: Installation
This chapter describes the installation procedure for the PRO115 stage, including handling the stage properly, preparing the mounting surface to accept the stage, securing the stage to the mounting surface, attaching the payload, and making the electrical connections.
Installation must follow the instructions in this chapter. Failure to follow these instructions
could result in injury and damage to the equipment.
2.1. Unpacking and Handling the Stage
Carefully remove the stage from the protective shipping container. Set the stage on a smooth, flat, and clean
surface. This is a simple, yet very important step in maintaining the integrity of the stage. Each stage has a
label listing the system part number and serial number. These numbers contain information necessary for
maintaining or updating system hardware and software. Locate this label and record the information for later
reference. If any damage has occurred during shipping, report it immediately.
Improper stage handling could adversely affect the stage’s performance. Use care when
moving the stage. Manually lifting or transporting stages can result in injury.
Lift the stage only by the base.
Do not use the ballscrew or motor as lifting points
www.aerotech.com
Chapter 2
15
Installation
PRO115 Series Stage User's Manual
2.2. Preparing the Mounting Surface
The mounting surface should be flat and have adequate stiffness in order to achieve the maximum performance from the PRO115. When an PRO115 series stage is mounted to a non-flat surface, the stage can
be distorted as the mounting screws are tightened (see Figure 2-1).
Figure 2-1:
Mounting to a Flat Surface
N O T E : To maintain accuracy, the mounting surface should be flat, as specified in Table 2-1.
Any distortion will decrease the overall accuracy of the stage. Adjustments to the mounting surface must be
done before the stage is secured.
N O T E : The stage base is precision machined and verified for flatness prior to stage assembly at the factory. If machining is required to achieve the desired flatness, it should be performed on the mounting surface rather than the stage base. Shimming should be avoided if possible. If shimming is required, it should
be minimized to improve the rigidity of the system.

Installation
2.3. Securing the Stage to the Mounting Surface
If necessary, manually move the stage table to access the 6.5 mm (0.28 in) diameter mounting holes along
the edges of the stage (refer to Figure 2-2). This stage is designed to use socket head cap screws (SHCS) to
secure the base to the mounting surface. Use M6 x 22 mm or ¼ x 7/8” long SHCS with flat washers to
achieve 1.5x diameter thread engagement. Torque the mounting screws to 8.1 N*m (6 ft*lb).
N O T E : The stage table may offer a considerable amount of resistance when it is moved manually. This is
especially true if the stage is fitted with a motor assembly.
N O T E : If the stage is not connected to a power source, and not equipped with an optional brake, it should
be possible to move the stage table by hand with steady even pressure. Do not attempt to manually move
the stage if it is connected to a power source or includes an integrated brake.
The stage must be mounted securely. Improper mounting can result in injury and damage to
the equipment.

2.4. Attaching the Payload to the Stage
To prevent damage to the stage or parts, test the operation of the stage before any payload is mounted to the
stage tabletop. Proceed with the electrical installation and test the motion control system in accordance with
the system documentation. Document all results for future reference. For information on electrical connections, refer to the Electrical Installation section later in this chapter, the documentation of the motion control system delivered with the stage, and the wiring drawings in Chapter 3: Operating Specifications.
The payload must be flat, rigid and comparable to the stage in quality.
N O T E : For valid accuracies, the mounting interface should be flat within 1 µm per 50 mm.
Refer to Section 3.4. for information on cantilevered loads and load positioning.
N O T E : Do not attach a payload to the stage table with screws that are too long. A screw passing through
the stage table can come into contact with the hardcover, affecting travel and possibly damaging the stage.

2.5. Electrical Installation
Electrical installation requirements will vary depending on stage options. Installation instructions in this section are for stages equipped with standard Aerotech motors intended for use with an Aerotech motion control
system. Contact Aerotech for further information regarding stages that are otherwise configured.
Aerotech motion control systems are adjusted at the factory for optimum performance. When the PRO115
series stage is part of a complete Aerotech motion control system, setup involves connecting a stage and
motor combination to the appropriate drive chassis with the cables provided. Connect the provided cables to
the appropriate electrical connectors on the stage shown in Figure 2-3. Labels on the drive indicate the appropriate connector locations. Refer to your drive manuals and documentation for additional installation and operation information. In some cases, if the system is uniquely configured, a drawing showing system
interconnects is supplied.
Figure 2-3:
Electrical Components of a Typical PRO115 Stage
Never connect or disconnect any electrical component or connecting cable while power is
applied, or serious damage can result.
The stage's protective ground is located on pin A4 of the Motor Wiring connection. If you are
using cables other than those provided by Aerotech, you must connect pin A4 to a ground
connection.

2.5.1. Standard Aerotech Motor Options
The BMS60, one of Aerotech’s high performance brushless, slotless rotary motors, is the standard motor for
the PRO115 stage. The electrical wiring from the motor and encoder to the “connectorized” ports on the motor
can is contained within the rear motor housing and has been completed at the factory. The motor cables and
limit cable convey motor power, encoder feedback, and limit switch signals to an appropriate hardware
device (e.g. axis controller or amplifier). Refer to Section 3.6. for standard motor wiring and connector pin outputs.
2.5.2. Motor Foldback Options
When the foldback option is chosen, any motor with a standard NEMA 23 frame size may be used. Either a
6.35 mm (1/4”) shaft or a 9.53 mm (3/8”) shaft size can be specified when ordering the stage. The belt pulleys
are attached to the motor shaft with two set screws. See Figure 4-5 and Figure 4-6 for illustrations showing
the locations of the set screws as well as the entire pulley and belt power transfer system. Refer to Section
4.3. for more information about the foldback option.
2.5.3. Optical Limit Switches
The PRO115 is equipped with optical limit switches, which can be configured as a 5 volt normally closed (5VNC), 5 volt normally open (5V-NO), or 24 volt normally closed (24V-NC). The limit cable exits the stage on
the same side as the motor and is bundled with the motor cables. The customer has the option of flying leads
or a 9-pin D connector for the end of the limit cable. Refer to Section 3.5. for a description of limit switch operation and wiring.

Chapter 3: Operating Specifications
The surrounding environment and operating conditions can affect the performance and service life of the
stage. This chapter provides information on ideal environmental and operating conditions. Also included are
instructions for estimating load capability and torque required to turn the ballscrew given various loadings.
3.1. Environmental Specifications
The environmental specifications for the PRO115 are listed in the following table.
Table 3-1:
Environmental Specifications
Ambient
Temperature
Operating: 10° to 35° C (50° to 95° F)
The optimal operating temperature is 20° C ±2° C (68° F ±4° F). If at any time the operating temperature deviates from 20° C degradation in performance could occur. Contact Aerotech for
information regarding your specific application and environment.
Storage: 0° to 40° C (32° to 104° F) in original shipping packaging
Humidity
Operating: 40 percent to 60 percent RH
The optimal operating humidity is 50 percent RH.
Storage: 30 percent to 60 percent RH, non-condensing in original packaging
Altitude
Operating: 0 to 2,000 m (0 to 6,562 ft) above sea level
Contact Aerotech if your specific application involves use above 2,000 m or below sea level.
Vibration
Use the system in a low vibration environment. Excessive floor or acoustical vibration can affect
stage and system performance. Contact Aerotech for information regarding your specific application.
Dust Exposure
The PRO115 stages have limited protection against dust, but not water. This equates to an
ingress protection rating of IP50.
Use
Indoor use only
Do not expose the stage to environments or conditions outside the specified range of operating environments. Operation in conditions other than those specified can cause damage to
the equipment.
3.2. Accuracy and Temperature Effects
The accuracy specification of PRO115 series stages is measured at the center of travel 25 mm above the
table with the stage in a horizontal position. The stage is assumed to be fully supported by a mounting surface meeting or exceeding the specification in Table 2-1.
The accuracy of the ballscrew is a key element in the overall positioning accuracy. A scale error can be
expected if temperature of the ballscrew differs from 20° C (68° F). The greater the temperature difference,
the greater the error. The temperature of the ballscrew depends on the speed and duty cycle of the stage. The
faster the movement and higher the duty cycle, the more the stage accuracy will be affected by heat. The thermal expansion coefficient of the ballscrew is 11.7 x 10-6 ppm/°C.

3.4. Load Capability
It is recommended that application loads be symmetrically distributed whenever possible (i.e., the payload
should be centered on the stage table and the entire stage should be centered on the support structure). With
the stage lying flat (horizontal) and the application load vertically applied and symmetrically distributed, the
maximum vertical load carrying capacity of PRO115 stages is 40 kg. If cantilevered loads are applied, refer to
Figure 3-1 to find the maximum allowable load.
In Figure 3-1, three curves are shown for different loading conditions. The Vertical curve is for situations
where the stage is mounted in a vertical orientation and the payload is mounted to the table top with its center
of gravity extended outward (5 mm lead version only). The Horizontal curve assumes a horizontal stage orientation. If a cantilevered load situation is used, first determine if it is a vertical cantilever or side cantilever system based on Figure 3-2. Measure the cantilever length, then find the corresponding load value from Figure 31.
Figure 3-1:
Load Capability of PRO115 Series Stages
N O T E : The Vertical curve only applies to the 5 mm lead version. The 20 mm lead version cannot be used
vertically.

3.5. Optical Limit Switch
PRO115 series stages are provided with a pair of optical limit switch assemblies mounted to the base of the
stage. The limit switches signal when the stage has reached its maximum useable travel distance in both
directions.
3.5.1. Limit Switch Operation
Each limit switch has a light source and detector mounted to a small printed circuit board. Each limit switch
board is mounted at an end of the stage with its emitter–detector axes perpendicular to the direction of table
motion. On a standard stage, the clockwise (CW) switch is located at the end opposite the motor. When
movement of the stage table causes the blade mounted to the stage carriage to break the light beam from the
emitter to the detector, a CW or counterclockwise (CCW) limit signal is generated. The limit switch itself can
be configured as normally closed (NC) or normally open (NO). The -24V-NC option is a factory option only.
If the stage is driven past the electrical limit, it will encounter the hard stop. Where the hard
limit occurs is dependent on stage travel. In stages with a 5 mm lead ballscrew, the hard
limit occurs ~2 revolutions (10 mm) for the 50 mm travel stage and ~1 revolution (5 mm) for
the 600 mm travel stage. In stages with a 20 mm lead ballscrew, the hard limit occurs ~2.8
revolutions (57 mm). Although the operating speed of the stage may be relatively slow, and
the stage’s rubber bumpers will provide some protection, damage to the stage could result.
Figure 3-4:
Internal View of a Typical Stage Showing Limit Switches
N O T E : Clockwise (CW) and counterclockwise (CCW) refer to the direction of motor rotation while looking into the shaft of the motor. For the PRO115, a CW rotation of the motor causes the stage table to move
away from the motor. CCW rotation of the motor causes the stage table to move toward the motor. If an
optional "foldback" option is used, the directions are reversed.

3.5.2. Limit Switch Wiring
Limit switches are open-collector, TTL–compatible, electro–optical devices that change output states when
the stage approaches its maximum travel distance and breaks the light beam. Since they are open-collector
devices, they may be interfaced to 5-24 Volt logic inputs. Each limit switch is mounted on a small printed circuit board. Standard PRO115 stages include wiring in a separate 9-pin limit switch connector, detailed in Figure 3-5.
Figure 3-5:
PRO115 Series 9-pin Limit Switch Wiring
In all PRO115 Series Stages with the -24V-NC limit option, pin 1 of the 9-pin Limit Switch
will always be the power for the limits. You must connect either 5V DC or 24V DC based on
the option you have purchased.

Chapter 3

Operating Specifications
PRO115 Series Stage User's Manual
Assuming a -5V-NC limit configuration, the input to the controller is seen as a logic 0 (typical 0.4V @ 12.8
mA) when no limit condition is present. When the limit switch is activated, a 5V source through a pull-up
resistor, on the controller, causes a logic 1 (typically 4.8-5 V) to be seen by the controller input. The limit
switch operation for a NO limit configuration is the exact opposite as described above. See Figure 3-6 for a
diagram of limit switch wiring. The switch shown in Figure 3-6 is a PNP transistor (NPN for the -24V-NC
option).

N O T E : Refer to the other documentation accompanying your Aerotech equipment. Call your Aerotech
representative if there are any questions on system configuration.
N O T E : If you are using your own cables to connect the stage, ensure that motor and ground wires can
handle current higher than the continuous motor current listed in Table 3-5. The voltage rating of the wire
insulation must be greater than the maximum drive output voltage.

3.7. Vacuum Operation
Aerotech can specially prepare the PRO115 series stage for operation in vacuum environments. Aerotech
offers two vacuum preparation options; one for low vacuum (for use in atmospheric pressures to 10-3 torr)
and one for high vacuum (preparation for environments from 10-3 to 10-6 torr). As part of this preparation,
attention to detail during modification, cleaning, and assembly results in stages with optimal performance in
vacuum applications. This chapter will outline preparation techniques for stages that will operate in a vacuum. Some techniques covered are:
l
Lubrication with vacuum–compatible lubricants
l
Use of materials, fasteners, and coatings with vacuum outgas performance compatible with the level of
vacuum specified
l
For high vacuum stages, elimination of situations that may allow gases to become temporarily trapped
during pump down
l
Extensive cleaning prior to assembly in a clean environment and packaging in a special polyethylene
bag
3.7.1. Special Guidelines
To ensure that the stage will continue to perform well in the vacuum environment, follow the guidelines listed
below (in addition to standard handling, installation, and lubrication guidelines outlined earlier in this manual).
1. Do not remove the stage from the sealed bag until it is ready for use.
2. Always handle the stage in a clean environment and use powder-free polyethylene gloves to prevent any
contaminants from adhering to the surface of the stage.
3. During installation, use cleaned, vented, stainless steel fasteners when securing the stage.
4. Reduced air pressure eliminates significant convective heat transfer. This, coupled with the viscous vacuum–compatible lubricants, could result in excessive motor operating temperatures. Because of this,
consider all continuous torque ratings to be 40 to 60% lower than the value specified for operation in normal atmospheric environment. Reduce motor usage accordingly.
5. For vacuum applications, the recommended lubricant is a small quantity of Braycote® 602EF grease or
a substitute of equal quality.
6. Baking vacuum components between 100 and 125 °C for 24 to 48 hours significantly reduces outgassing at initial pump-down to vacuum pressure and evaporates water vapor that impregnates porous
surfaces on the aluminum surfaces and Teflon cables. Aerotech recommends that customers bake out
vacuum systems when first installing them in the vacuum chamber.

Maintenance
Chapter 4: Maintenance
This chapter will cover information about intervals between lubrications, detail the lubrication and inspection
process, and cover which lubricants are recommended for use. Also included is a section on belt tension and
adjustment on stages with the foldback option.
N O T E : The bearing area must be kept free of foreign matter and moisture; otherwise, the performance
and life expectancy of the stage will be reduced. Always operate the stage with the hard cover and side
seals in place to help keep dirt out..
To minimize the possibility of bodily injury, confirm that all electrical power is disconnected
prior to making any mechanical adjustments.
4.1. Service and Inspection Schedule
Lubricant inspection and replenishment in PRO115 series stages depends on conditions such as duty cycle,
speed, and the environment. An inspection interval of once per month is recommended until a trend develops
for the application. Longer or shorter intervals may be required to maintain the film of lubricant on the bearing
surfaces. In general, it is recommended that stages operating in a clean environment be lubricated annually,
or every 500 km, whichever comes first. For stages operating under conditions involving excessive debris,
lubrication every six months is recommended. If the application process uses only a small portion of travel for
most of the duty cycle, it is recommended that the stage be periodically driven through full travel to redistribute the lubrication in the bearings and ballscrew. The ballscrew end bearings and motor bearings are
sealed, and should not need to be relubricated under normal use.

Maintenance
PRO115 Series Stage User's Manual
4.2. Cleaning and Lubrication
4.2.1. Recommended Cleaning Solvents
For standard ballscrew assemblies and LMG guide rails, THK AFE-CA grease is recommended.
If a solvent is necessary for cleaning the stage, it is recommended that isopropyl alcohol be used. Harsher
solvents, such as acetone, may damage the plastic and rubber seals on the ballscrew or LMG trucks. If acetone is required, avoid the screw and bearing seals.
For high-speed applications (i.e., near maximum speed at a duty cycle of 50%), frequent ballscrew maintenance with standard lubricants is required.
4.2.2. Important Notes on Lubrication
When cleaning and/or lubricating components of the PRO115 series stages:
1. Be sure to use a clean, dry, soft, lint–free cloth for cleaning.
2. Take the opportunity during the lubrication procedure to inspect the linear motion guides for any damage
or signs of wear.
3. In applications that have multiple stages bolted together to form multiaxis systems, the orthogonality
may be lost if the stage tables of the support stages are loosened. Precision aligned stages should not
be loosened or disassembled.
4. Further disassembly of the stage is not recommended because proper assembly and calibration can
only be done at the factory. In addition, a laser interferometer is required for post assembly verification to
maintain warranties.
4.2.3. Lubrication and Cleaning Process
The lubrication and cleaning process is outlined in the steps that follow. Before beginning lubrication, see
Section 4.2.1. for recommended lubricants.
1. Drive the stage table to one end of travel (Figure 4-1) and remove power to the stage.
2. Remove the screws on the edges of the hard cover (Figure 4-2) and slide it out from the side opposite of
the motor (Figure 4-3). This can be done without removing the table.
3. Remove any accumulated dust or debris from the inside of the assembly.
4. Remove any dirty or dried lubricant from the ballscrew. Use a clean, lint-free cloth with a side-to-side
motion. Manually turn the ballscrew to clean its entire circumference. A swab soaked in Isopropyl Alcohol may be used to remove stubborn debris.
5. Clean the end of the ballscrew nut and wiper with a clean, lint-free cloth or swab.
6. Clean the linear bearing guides using a similar technique.
7. Apply a thin, continuous film of lubricant to the ballscrew threads and linear bearing guides. A good quality, natural bristle artist's brush makes an excellent applicator.
8. For stages without an optional brake, manually move the stage to the opposite end of travel. This will
work the grease into the ballscrew and linear bearing guides. If the stage has an optional brake, the
stage cannot be moved by hand. In this case, restore power to the stage, drive it to the desired position,
then remove power and continue to Step 9. Be sure to use extreme caution while operating the stage
temporarily without the hardcover installed.
9. Repeat steps 3 through 7 for any areas covered by the original table position.

4.3. Belt Adjustment
This section applies only to stages equipped with foldback motor options. On foldback stages, the motor
torque is transferred to the ballscrew via a timing belt. Belt tension is critical to stage performance and accuracy.
Figure 4-4:
Foldback Motor Option Example
When lubricating and cleaning the stage, it is recommended that belt tension be checked. Deflection in the
belt should be less than 5 mm when applying a downward force directly between the pulleys (Figure 4-5) of
approximately 5 N. If deflection exceeds this range, the belt tension should be adjusted. The method of
adjustment is outlined below.
1. Remove power to the stage.
2. Remove the four mounting screws for the foldback cover (Figure 4-5).
3. Check the tension in the belt to determine if adjustment is necessary.
4. If adjustment is required, loosen (but do not remove) the four motor mounting screws (Figure 4-5).
5. The motor mounting holes are slotted to allow for belt adjustment (Figure 4-6). With all four screws
loose, pull the motor away from the stage by hand until achieving the necessary belt tension.
6. Tighten motor mounting screws and re-check the tension in the belt. Belt tension may change after the
mounting screws are tightened, so if necessary repeat step 5 until desired tension is reached.
7. While adjusting tension, it is advisable to verify that the pulleys are tight on their respective shafts. Each
pulley is held in position with two set screws (Figure 4-6). If a pulley is loose, it may be necessary to
tighten one or both of these screws.
8. Once tension adjustment is complete, replace the foldback cover and mounting screws. Restore power
to the stage.
