M-230 Linear Actuators MP102E Version: 1.2 3
2.1 Intended Use
The M-230 is a laboratory device as defined by DIN EN 61010-1. It is intended to be
used in interior spaces and in an environment which is free of dirt, oil, and lubricants.
Based on its design and realization, the M-230 is intended for positioning, adjusting
and shifting loads in one axis at various velocities.
The intended use of the M-230 is only possible when installed and with a suitable
controller (p. 11). The controller is not included in the scope of delivery of the M-230.
2.2 General Safety Instructions
The M-230 is built according to state-of-the-art technology and recognized safety
standards. Improper use can result in personal injury and/or damage to the M-230.
Only use the M-230 for its intended purpose, and only use it if it is in a 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 M-230.
2.2.1 Organizational Measures
User manual
Always keep this user manual available by the M-230.
The latest versions of the user manuals are available for download on our
website.
Add all information given by the manufacturer to the user manual, for example
supplements or Technical Notes.

If you pass the M-230 on to other users, also turn over this user manual as
well as other relevant information provided by the manufacturer.
Only use the device on the basis of the complete user manual. Missing
information due to an incomplete user manual can result in minor injury and
property damage.
Only install and operate the M-230 after having read and understood this user
manual.
Personnel qualification
The M-230 may only be installed, started up, operated, maintained and cleaned by
authorized and appropriately qualified personnel.
2.2.2 Safety Measures during Installation
A cable break leads to a failure of the linear actuator.
Install the linear actuator so that the cable is not bent or squeezed too
severely during operation.
Lateral forces that affect the pusher of the linear actuator increase the friction on the
internal drive components. Increased friction impairs the motion of the pusher and
increases wear on the drive components.
Avoid lateral forces on the tip and on the pusher of the M-230.
The motion of the pusher can be hindered by a mounting nut that has been tightened
too strongly. This reduces the positioning accuracy.
Tighten the mounting nut to a maximum torque of 1.7 Nm.
The heat produced during operation of the M-230 can affect your application.
Install the M-230 so that your application is not affected by the dissipating
heat.

M-230 Linear Actuators MP102E Version: 1.2 5
2.2.3 Safety Measures during Start-Up
A motorized linear actuator can generate powerful forces depending on the gear ratio.
Connecting a linear actuator to an unsuitable controller can cause damage to the
linear actuator or controller.
Connect a linear actuator with DC motor to a DC motor controller only.
Connect a linear actuator with stepper motor to a stepper motor controller
only.
Faulty motor controllers can cause unintentional motor motion and run the M-230 into
the hard stop.
The linear actuator can perform an unintentional motion when connecting it to the
motor controller.
Do not place any objects in areas where they can get caught by moving parts.
Keep your fingers at a safe distance from the motion range of the M-230.
The collision of moving parts with the hard stop (end of travel range), as well as high
acceleration, can cause damage to, or considerable wear on the mechanical system.
In the event of a malfunction of the motor controller, stop the motion
immediately.
Ensure that the end of the travel range is approached at low velocity.
Set your control signal so that the moving part does not stop abruptly or try to
continue moving at the end of the travel range.
Determine the maximum velocity for your application.
Ensure that the automatic limit switch halt is supported by the controller, or
that it is activated in the controller.
2.2.4 Safety Measures during Operation
For models with DC motors:
Unsuitable settings made to the servo-control parameters can impair the performance
of the M-230. The consequences of this can be expressed as follows:
Oscillations
Imprecise approach of the position

6Version: 1.2 MP102E M-230 Linear Actuators
Settling time is too long
If the performance of the M-230 is not satisfactory, check the settings for the
servo-control parameters of your controller.
2.2.5 Safety Measures During Maintenance
The M-230 is precisely aligned.
Do not loosen any sealed screw.
