10 Troubleshooting and remedial action
During actuator operation, the actuator may fail to function properly due to an improper
setting or wiring. When the actuator cannot be operated properly, refer to the contents
provided in this section and take an appropriate action. If the problem persists, contact your
nearest Oriental Motor sales office.
Phenomenon
Possible cause
Remedial action
While push-motion
operation is executed, the
ball screw shaft does not
move with being jammed
in the nut part.
The ball screw shaft was
stopped by hitting against
a load or others at a speed
exceeding the maximum push
speed (6 mm/s).
Return the ball screw shaft at the
recommended speed shown in the
table below, and check if the ball
screw shaft and the load are not
damaged.
The ball screw shaft does
not move with being
jammed.
The operation was executed
under conditions where
the speed or the load was
exceeded the specification
value.
Return the ball screw shaft at the
recommended speed shown in the
table below. After that, check the
following items.
•
Are the ball screw shaft and the
load damaged?
•
Are the positions of the set collar
and the home position displaced?
The ball screw shaft
does not operate at the
command speed.
The torque of the actuator is
not enough against a load.
Review the load.
The ball screw shaft rotates
idly. (for non-guide type
actuator)
An anti-spin mechanism is not
provided.
Be sure to provide an anti-spin
mechanism for the non-guide type
actuator.
Malfunction of actuator
•
The installation accuracy is
low.
•
A load moment exceeding
the specification value is
applied.
•
Check the installation accuracy.
•
Use the actuator with a load
moment of the specification value
or smaller.
The thrust force of the
actuator has lowered.
•
The wiring distance is
exceeded the specification
value.
•
The viscosity of the grease
was changed.
•
Keep 20 m (65.6 ft.) or less for
the wiring length between the
actuator and driver.
•
Refer to p.29, and check the
operating ambient temperature.
