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 output
torque, allowable moment of inertia,
acceleration/deceleration and speed, and
adjust them appropriately.
3
Causes may include depletion of grease, brake
failure and motor failure.
Have a visual inspection to check on the gears
inside ELECYLINDER for dry-up of grease.
If the grease is dried up, supply 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 main frame may have been distorted when
mounting the ELECYLINDER, increasing the
sliding resistance.
The ELECYLINDER mounting surface should
be a machined surface or a plane with similar
accuracy, with flatness within 0.05 mm/m.
Refer to the recommended tightening torque of
the bolts for main frame fixing in "2.3 Installation
method".
5
The peak power capacity of the 24 V power
supply is less than 4.2 A.
Use a power supply with peak current of 4.2 A
or higher (per axis).
6
If the diameter of the power wire is less than
AWG18 (thin), the peak current may not flow
due to increased resistance value or contact
failure at the connection terminal.
Make sure that the wiring for power supply use
is AWG18 and that there is no looseness,
contact failure, disconnection or the like at the
connection terminal / connector etc.
7
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.
8
24 V power was turned ON while the moving
parts of the ELECYLINDER were immobilized
or pressed against the mechanical stopper.
Resolve the state of immobilization.
If the unit is pressed against the mechanical
stopper, move it at least 5 mm away, then turn
ON the power again.
