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
