Precautions
1. Do not attempt to establish the settings for the speed and acceleration/deceleration above
the allowable range.
An operation with speed and acceleration/deceleration beyond the allowable range may cause an abnormal
noise, vibration, malfunction or shortened life.
2. Back and forth operation in short distance may wear out the oil film of the grease.
If the actuators are moved back and forth continuously over a short distance of 30 mm or less, grease film
may run out. As a guide, move the actuators back and forth repeatedly for around 5 cycles over a distance of
50 mm or more after every 5,000 to 10,000 cycles. Keep using the actuators with the grease worn out may
cause malfunction. If it is extreme, flaking may occur on the guide.
3. Do not attempt to apply a rotary torque
Doing so may damage the internal component such as the rod stopper, and may result in an operation failure.
4. The allowable load moment for the flat type should be within the allowable range.
If the robot is operated under a load equal to or greater than the allowable load moment, abnormalnoise or
vibration, failure, or shorter life may result. In an extreme case, flaking may occur. If it is extreme, flaking may
occur on the guide.
5. For the model equipped with the home-position check sensor (Model: HS), do not attempt
to have the home return speed setting faster than the initial setting at the time the product
was delivered.
Because the home-position check sensor switch is stored inside the body on the motor end, it may get
damaged if the setting is made faster than the initial.
6. Make sure to attach the actuator properly by following this instruction manual.
Using the product with the actuator not being certainly retained or affixed may cause abnormal noise,
vibration, malfunction or shorten the product life.
7. Ensure use of the product in the specified conditions, environments and ranges.
An operation out of the guarantee may cause a drop in performance or malfunction of the product.
