Alarm group A: Overload alarm
Moving parts of ELECYLINDER stopped abnormally while moving to the target position.
No. Cause Countermeasure
1 Operation may not be possible due to contact
with or snagging on external obstacles. Remove any external obstacles or other
external loads.
2 The ELECYLINDER may be being used under
conditions exceeding the specifications
described in the catalog. Check the specification values such as
payload, acceleration/deceleration and speed,
and adjust them appropriately.
3 Causes may include foreign matter, brake
failure or motor failure. Visually check for the depletion of grease on
the ball screw / guide inside the
ELECYLINDER, intrusion of foreign matter, etc.
If this is the case, clean the inside of the
ELECYLINDER and replenish the grease.
Remove the motor and check the sliding
movement of the ELECYLINDER body.
If there is no abnormality in the sliding motion,
there is a possibility of motor or brake failure.
Replacement of the motor is recommended.
4 The base may have been distorted when
mounting the ELECYLINDER, increasing the
sliding resistance of the guide. The ELECYLINDER mounting surface should
be a machined surface or a plane with similar
accuracy, with flatness within 0.05mm/m.
Refer to the recommended tightening torque of
the bolts for base fixing in “2.3 Installation
method”.
5 The power voltage on 100 V AC (or 200 V AC)
has dropped. Check on the power voltage of 100 V AC (or
200 V AC).
In case it has been dropped, take a
counteraction so it gets back to the specified
power voltage.
In case a cable below AWG14 is used, apply
one with AWG14.
6 The deceleration distance was insufficient and
the calculation result of the arrival position
exceeded the operation range of the
ELECYLINDER due to the “next movement
command” being issued too soon during
operation with “Smooth accel/decel setting”
enabled. Adjust the timing of the “next movement
command” so that the command will be given
after the first movement is completed.
7 24 V DC and 100 V AC was turned on while
the driving part on ELECYLINDER is locked or
in condition of being forced at the mechanical
stopper. Resolve the state of immobilization.
Also, when it is forced at the mechanical
stopper, move it away from the stopper for
5mm or more before turning 24 V DC and 100
V AC (or 200 V AC) back on.
