Handling Precautions
1. Do not set a speed or acceleration/deceleration exceeding the applicable
rating.
Do not set a speed or acceleration/deceleration exceeding the applicable rating. Doing so may result in vibration,
failure or shorter life. If an acceleration/deceleration exceeding the rating is set, creep may occur or the coupling
may slip.
2. Keep the load moments to within the allowable value.
Keep the load moments to within the allowable value. If a load exceeding the allowable load moment is applied,
the life of the actuator may be reduced. In an extreme case, even flaking may occur.
3. Keep the overhang length to within the allowable value.
Keep the overhang length of the load to within the allowable value. If the overhang length exceeds the allowable
value, vibration or noise may occur.
4. Grease film may run out after back-and-forth operations over a short
distance.
Grease film may run out if the actuator is moved back and forth continuously over a distance of 30 mm or less. As
a guide, perform a back-and-forth operation five times or over a distance of 50 mm or more after a back-and-forth
operation over such short distance has been repeated 5,000 to 10,000 times. This will restore oil film.
5. Turn on the servo after making sure the slider or rod is away from the
mechanical end.
If the servo is turned on when the slider or rod is positioned near the mechanical end, the pole phase may not be
detected and a pole non-confirmation error or excitation detection error may occur.
Accordingly, turn on the servo after making sure the slider or rod is away from the mechanical end.
6. Make sure to attach the actuator properly by following this operation manual.
Using the product with the actuator not being certainly retained or affixed may cause abnormal noise, vibration,
malfunction or shorten the product life.
