Checking the work carried out

Risk of electric shock
Voltage is induced at the power connections of the primary section each time a primary
section moves with respect to a secondary section – and vice versa. If you touch the power
connections you may suffer an electric shock.
• Do not touch the power connections.
• Connect the motor cable ports correctly, or insulate them properly.
5.4.7.1

Smooth running of the slide

Checking the smooth running of the slide
The motor assembly must be specially checked for the smooth running of the slide.
● Remove all tools and objects from the traversing range.
● Clean the magnetic surface with a cloth before moving the slide.
If the guidance system is precisely aligned, it must be possible to move the moving part of
the motor with a force that remains constant over the entire traversing range. A slight
fluctuation in force is permissible. The force fluctuation results from the system-related
residual force of the linear motor.
● If excessive sluggishness results locally, check the air gap and the alignment of the
guidance system.
Note
Increased shifting force or force ripple
When checking the smooth running of the slide, ensure that the power connections of the
motor cable are not connected to the drive. In addition, the power connections must not be
"short-circuited". In these cases, a greater shifting force or force ripple occurs.
