Rotary actuator
doesn
’t move
Supply pressure isn
’t
applied correctly.
Correctly set the regulator at the supply
pressure side.
17
The directional switching
valve (such as a
solenoid valve) doesn
’t
switch.
Correctly apply a signal to the
directional switching valve (such as a
solenoid valve).
21
Air leakage from piping.
Inspect the piping and stop the
leakage.
21
The restrictor in the port
is clogged.
Clean the restrictor.
Take the following countermeasures:
(1) Blow air through the piping again.
(2) Inspect the air filter.
23
Operation is not
smooth.
(stick-slip)
A load has some friction.
Reduce the friction resistance.
22
Actuator axis and mating
axis not aligned.
Align the two centers or use a flexible
fitting.
22
Insufficient output due to a
low supply pressure.
To obtain stable operation, adjust the
supply pressure so that the load rate
becomes 50% or less.
18
Extreme rotating
angle changes.
Internal parts are
broken.
Replace with a new actuator.
Please do the following treatment on that.
(1) Calculate the kinetic energy applied to
the rotary actuator, and adjust the
load and rotating speed so that the
kinetic energy will be within the
allowable range.
(2)
Please install the stopper or the
shock absorber outside and absorb the
impact power.
In this case, please
provide a buffer angle to the stroke of
the actuator
（
Use 100° actuator in the
case of 90° stroke and use 190°
actuator in the case of 180° stroke.
）
and touch it to an external stopper or
the shock absorber surely.
