2. Precautions at Installation, Moving and Storage
2.1 Installation of the Motor
Mounting the motor the wrong way or at an inappropriate position may cause the
deterioration of accuracy, shortening of the product’s lifetime and a failure of the motor.
Please be sure to observe the following precautions.
Mounting Direction
Mount the motor in one of the directions shown
in the figures at right. If the motor is to be
mounted vertically, mount it so that the encoder
unit faces upward. If foreign substances or
grease enter the encoder unit, the motor may
malfunction or break down.
Installation Location
The motor is intended to be used in normal
indoor conditions.
•
Well ventilated places with little dust
and debris
•
Avoid installing the motor in an
atmosphere with high
temperature/high humidity or which
contains dust, dirt, metal powder,
corrosive gasses, etc.
Mechanical Connection
•
The levelness of the load surface with respect to the slider’s load mounting surface
must be 0.01 mm or less.
•
The clearance between the slider and mounting plate is approximately 0.1 mm. Dirt or
foreign substances adhering to the base surface may cause failures.
•
The motor mounting plate of products whose surface treatment suffix code is "N" is
coated to prevent rust. Before mounting, wipe the coating of the base mounting surface
completely with organic solvent (e.g. thinner, hydrocarbon solvent). If any coating
remains, the mechanical precision and functions may be impaired. Prevent areas other
than the base mounting surface, such as the core surface and guide unit, from being
subjected to the solvent and any remaining coating. Failure to do so may cause
deformation and breakdown. However, do not wipe off the grease in the guide unit.
•
The tightening torque of screws for mounting the mounting plate and load on the slider
must be 4 Nm for M4 screws, 13 Nm for M6 screws, 35 Nm for M8 screws, and 70 Nm
for M10 screws. Prevent screws from loosening by applying Loctite 601 or an equivalent
product.
