4. When the load is tobe stopped by the product with an external stopper or an external object
directly, utilize the
“pushing operation”. Do not stop the table with an external object by
positioning operation and in the range of the positioning operation.
If the product is used in the positioning operation, there may be galling or other problems when it
comes into contact with the external object.
5. When the table is stopped by pushing operation (stopping or clamping), set the product to a
position of at least 1
o
away from a work piece (This position is referred to as a pushing start
position).
If the pushing operation (stopping or clamping) is set to the same position as the externally stopping
position, the following alarms may be generated and operation may become unstable.
a. “Posn failed” alarm
The product cannot reach a pushing start position due to the deviation of work pieces in
width.
b. “Pushing ALM” alarm
The product is pushed back from a pushing start position after starting to push.
c. “Err overflow” alarm
The displacement at the pushing start position exceeds the specified range.
6. If the table is stopped by an external object, there is no backlash effect in pushing operation.
The return to origin position is set by pushing operation.
7. In the external stopper specification, an angle adjustment screw (adjuster bolt) is mounted as
the standard specification.
The rotation angle adjustment range is +/-2
o
from the angle rotation end.
If the adjustment range is exceeded, the rotation angle may change due to insufficient strength of the
external stopper.
The angle adjustment of the adjuster bolt is 1
o
/rotation (reference).
8. In case that gravity is added to the work-piece along the rotation direction when product is
mounted vertically, the work-piece may fall down when "SVON" signal is OFF or EMG is not
energizing.
9. When mounting the product, keep a 40 mm or longer diameter for bends in the motor cable.
10. Grounding method of the actuator.
1. The cross-sectional area of this wire shall be a minimum of 2 mm
2
.
2.
Avoid common grounding with other devices.
6.4 Maintenance
1. The high precision bearing is assembled by pushing into position. It is not possible to
disassemble it.
