6 PRS-200 Precision Rotation Stage
2.2.3 Measures during Start-Up
Do not put your PRS-200 into operation until it is fully mounted and
connected.
Your system can be damaged by uncontrolled oscillation of the PRS-200.
Noise generated during operation of the PRS-200 is a typical sign of
oscillation.
Immediately switch off the servo-control system of the affected rotational
axis.
Check the settings of the servo-control parameters.
Moving parts attached to devices with motorized rotation stages can
accelerate rapidly and generate high forces which can cause injury or
damage to equipment.
Unintentional motion of the rotation 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 functioning of the limit switches at velocities between 10 %
and 20 % of the maximum velocity.
In the event of a malfunction of the limit switches, stop the 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.
Determine the maximum velocity for your application.
2.2.4 Measures during Operation
If noise occurs during operation of the PRS-200, check the settings of
the 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 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 PRS-200 is precision adjusted.
Do not loosen any sealed screws.
Dirt, oil, lubricants and condensation will render the motor/drive inoperable.
Keep the PRS-200 free of lubricants.
Keep the PRS-200 free from dirt and condensation.
