2.13 AUXILIARY BRAKE MEASURES
The linear motor allows the dynamic brake to be applied by
connecting the power line. If an object being moved weighs much or
moves at high speed, a longer coasting distance is required. If there is
no sufficient stroke margin, a collision against a stroke end can occur,
resulting in a damage to the machine. So, a mechanical brake or shock
absorber needs to be additionally installed.
The motor itself does not have a mechanical brake, so that a
mechanical brake is needed to preserve the position at power-off time.
This is because strong magnetic attraction can cause the motor to
move freely to the magnetically stablest position even with the
horizontal axis. Note that with the vertical axis, in particular, the
motor makes a downward movement.
