can be checked, for example, by means of
gauge blocks and feeler gauges before the motor is installed.
Note
The applicable installation dimensions can be found in the following
documents:
S /PJLM/ Configuration guide for linear motor
S The data sheet of the appropriate 1FN1 or 1FN3 motor.
Please note with respect to installation dimension and air gap:
The electrical and system-related properties of the linear motor are guaranteed
solely as a function of the installation dimension and not the measurable air
gap. The air gap must be large enough to allow the motor to move freely.
