Reported failure Major causes Countermeasures
Large overrun.
(Stopping accuracy
is low)
Check the peripheral
equipment of the lock unit.
①
Effective area of the
solenoid valve for locking
is too small.
Replace the solenoid valve to the one
with larger effective area.
②
Piping between the lock
release port and the
solenoid valve for locking
is long or the piping
diameter is small.
・
Install the solenoid valve for locking
close to the lock unit and shorten the
piping tube or, directly connect them.
・
Install a rapid exhaust valve close to
the lock unit piping port.
③
Poor response of the
solenoid valve for locking. Replace the solenoid valve to the one
with better response.
④
Poor response of the
solenoid valve for locking
to the auto switch for
signal detection.
Replace the switch with the auto
switch with better response.
⑤
[Proximity switch for
locking is installed outside
of the actuator]
There is a play with the
switch detector of the
proximity switch. The
shape of switch detector is
not suitable.
・
Adjust the switch detector to
eliminate the play.
・
Redesign the switch detector.
