Страница: 40 / 41

Problem Possible cause Solution
Air leakage from the
table
Piston seal is worn out.
The seal parts need to be replaced.
Contact SMC.
The pinion gear is
broken.
Excessive kinetic energy was
applied to the rotary table.
Replace the rotary table with the new one.
After that, take the measures below.
・
Calculate the kinetic energy applied to the
rotary table and adjust the load and rotation
speed to make the value within the allowable
kinetic energy.
・
Mount an external stopper or shock absorber
to absorb the impact force .
In this case, adjust so that the adjusting bolt
does not come into contact with the piston. Set
the rotation end with an external stopper.
・
Do
not apply external torque to the product that
exceeds the rated output.
（
when cushion equipped
）
Cushion needle adjustment is
not optimum. Kinetic energy is
not adsorbed by the cushion.
Replace by new actuator, and do followings.
1. Adjust the cushion needle at optimum
condition
2. Confirmation if kinetic energy generated
by the load is less than cushion
absorbable energy
Insufficient rotating
Angle.
The adjustment bolt for angle
adjustment is set at a smaller
angle than required.
Set the adjustment bolt correctly.
No allowance in actuator
rotation angle. Actuator
rotation angle deviated to the
external stopper.
Remove the external stopper to check the all
rotation range of actuator to set the external
stopper to the correct place.
（
When cushion equipped
）
Cushion needle is closed
Adjust the cushion needle
The auto switch will
not operate or
operates incorrectly.
The auto switch is mounted in
an inappropriate position.
Mount the auto switch in the correct position.
Effect of an external magnetic
field. Check that there is no strong magnetic field
present.
Trouble with the electrical
circuit Check that there is no trouble with the electrical
circuit.
Trouble with the electrical
specification Check there is no trouble with the electrical
specification.
