2.1 Intended Use
The LS-270 is a laboratory device as defined by DIN EN 61010. It is
intended for indoor use and use in an environment which is free of dirt, oil,
and lubricants.
In accordance with its design, the LS-270 is intended for positioning,
adjusting and shifting of loads at various velocities. The LS-270 can be
mounted horizontally or vertically.
The intended use of the LS-270 is only possible in conjunction with suitable
electronics. The following options are available:
1. Drive electronics and controller with suitable software
2. Combination device with suitable software
•The electronics are not included in the scope of delivery of the LS-270.
•The electronics must provide the required voltages. To ensure proper
performance of the servo-control system, the electronics must be able to
read out and process the signals from reference and limit switches, and
from the incremental position encoder.

2.2 General Safety Instructions
The LS-270 is built according to state-of-the-art technology and recognized
safety standards. Improper use of the LS-270 can result in personal injury
and/or damage to the LS-270.
Only use the LS-270 for its intended purpose, and only use it if it is in good
working order.
Read the user manual.
Immediately eliminate any faults and malfunctions that are likely to affect
safety.
The operator is responsible for the correct installation and operation of the
LS-270.
2.2.1 Organizational Measures
User Manual
•Always keep this user manual available when using the LS-270. If the
user manual is lost or damaged, contact our customer service
department (see chapter 10).
•Add all information from the manufacturer such as supplements or
technical notes to the user manual.
•Only use the device on the basis of the complete user manual. If your
user manual is incomplete and is therefore missing important
information, serious or fatal injury as well as damage to the equipment
can result.
•Only install and operate the LS-270 after you have read and understood
this user manual.
Personnel Qualification
The LS-270 may only be started up, operated, maintained and cleaned by
authorized and appropriately qualified personnel.
2.2.2 Measures during Installation
The LS-270 may be damaged by excessively long screws and wrongly
mounted parts.
•When mounting the LS-270, make sure that the mounting screws do not
interfere with the stage motion. The screw heads must not protrude from
the countersunk holes.
•Observe the depth of the mounting holes in the moving platform.
•Only use screws of the correct length for the respective mounting holes.
•Only mount the LS-270 and the loads on the mounting fixtures (holes)
intended for this purpose.
•The LS-270 heats up during operation. High temperatures can influence
your application.
•Install the LS-270 so that your application is not affected by the
dissipating heat.
•Cable extensions can affect the performance of the LS-270 and damage
the electronics.
•Only use genuine PI miCos parts to connect the LS-270 to the
electronics.
•Do not use cable extensions. If you need longer cables, use cable
extensions from PI miCos.
•Avoid short circuiting the lines for motor voltages since this can damage
the electronics.

6 LS-270 Linear Stage
2.2.3 Measures during Start-Up
•Do not put your LS-270 into operation until it is fully mounted and
connected.
Your system can be damaged by uncontrolled oscillation of the LS-270.
Noise generated during operation of the LS-270 is a typical sign of
oscillation.
•Immediately switch off the servo-control system of the affected stage
axes.
•Check the settings of the servo-control parameters.
Moving parts attached to devices with motorized stages can accelerate
rapidly and generate high forces which can cause injury or damage to
equipment.
Unintentional motion of the stage is possible when it is connected to the
controller for the first time. Defective software or incorrect operation of the
software can also result in unintentional motions.
•Do not place any objects in areas where they can be caught by moving
parts.
Collision of a part in motion at the end of the travel range and high
accelerations can cause damage to or wear on the mechanical system.
•Ensure that the automatic limit switch halt is supported by the controller,
or that it is activated in the controller.
•Do not disable the evaluation of the limit switch signals by the controller.
•Check the function of the limit switches at about 10% to 20% of the
maximum velocity.
•In the event of a malfunction of the limit switches, stop motion
immediately.
•Ensure that the end of the travel range is approached at low velocity.
Set the control signal so that the moving part does not stop abruptly or try to
continue motion at the end of the travel range.
•Determine the maximum velocity for your application.
2.2.4 Measures during Operation
•If noise occurs during operation of the LS-270, check the settings of the
servo-control parameters of your controller.
Highest dynamic force and holding force are achieved at a control signal
level of 100%; however, during continuous operation the motor/drive may
overheat.
•During continuous operation at room temperature, do not exceed a
maximum of 90% of the control signal level.
•For continuous operation at other temperatures, observe the maximum
permissible duty cycle in relation to the ambient temperature or contact
our customer service department for more information (see chapter 9).
2.2.5 Measures during Maintenance
The LS-270 is precision adjusted.
Do not loosen any sealed screws.
Dirt, oil, lubricants and condensation will render the motor/drive inoperable.
Keep the LS-270 free of lubricants.
Keep the LS-270 free of dirt and condensation.

This stage must be started up with a suitable cable and the associated
controllers.
7. MAINTENANCE
Depending on the operating conditions and the period of use of the LS-270,
the following maintenance measures are required:
Maintenance Run
The maintenance run is performed to redistribute the existing lubricant on
the guidings of the stage.
•To evenly distribute the existing lubricant on the stage guidings, perform
a maintenance run across the entire travel range after 500 hours of
operation, or after 1 year at the latest.
•If the stage is to be operated continuously in an industrial environment
over a small travel (less than 20 percent of the entire travel range),
perform a maintenance run across the entire travel range every 5000
motion cycles.
Lubrication
Under laboratory conditions, the guidings of the stage need to be lubricated
in exceptional cases only. For continuous industrial use, the lubrication
intervals must be defined individually.
•Do not lubricate the guidings of the LS-270 without consulting our
customer service department (see chapter 9).
•To lubricate the guidings, follow the instructions specified in the
maintenance manual, which you can obtain from our customer service
department.
