Troubleshooting
Problem
Possible cause
Solution
Rotary actuator
does not move
Supply pressure is not applied
correctly.
Correctly set the regulator at the supply
pressure side.
The directional switching
valve (such as a solenoid
valve) does not switch.
Correctly apply a signal to the directional
switching valve (such as a solenoid valve).
Air leakage from piping.
Inspect the piping and stop the leakage.
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.
Operation is not
smooth.
(stick-slip)
The load has some friction.
Reduce the friction resistance.
Actuator axis and mating axis
not aligned.
Align the two centers or use a flexible fitting.
Insufficient output due to a low
supply pressure.
To obtain stable operation, adjust the supply
pressure to make the load ratio appropriate.
Speed controller is restricted
too much.
Adjust the speed controller so that the rotating
marks will be in the adjusting range.
Extreme rotating
angle changes.
Internal parts are broken.
Replace the rotary actuator with the new one.
After that, take the measures below.
(1)Calculate the kinetic energy applied to the
rotary actuator and adjust the load and
rotation speed to make the value within the
allowable kinetic energy.
(2)Mount an external stopper or shock
absorber to absorb the impact force
.
In this case, provide a buffer angle to the
stroke of the actuator( Use 100
°
actuator in
the case of 90
°
stroke.) and touch it to an
external stopper or the shock absorber surely.
