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-232 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-232.
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-232. The consequences of this can be expressed as follows:
