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.
