Precautions in Operation
1. It is set to “high output” when the machine is delivered from the factory.
There is a limit in the duty for the high output setting. Even though the transportable weight and
maximum speed decrease, an operation with the duty 100% becomes available if the high
output setting is set invalid in the parameters.
See 1.2.1 Settings for Valid/Invalid of High Output Setting for more details.
2. Set the operation patterns.
There are some operation (PIO) patterns prepared for each model classified by the built-in
controller.
Set the operation pattern and parameters suitable for the operation method of each model.
See Chapter 4 Operation for more details.

Caution : Please note it is very risky when the control sequence and PIO pattern setting do not
match to each other. It may not only cause the normal operation disabled, but also
may cause an unexpected operation.
3. Do not set speeds and accelerations/decelerations equal to or greater than the
respective ratings.
If the actuator is operated at a speed or acceleration/deceleration exceeding the allowable
value, abnormal noise or vibration, failure, or shorter life may result.
4. The allowable load moment for the slider type should be within the allowable
range.
If the actuator is operated under a load equal to or greater than the allowable load moment,
abnormal noise or vibration, failure, or shorter life may result. In an extreme case, flaking may
occur.
5. The overhung for the slider type should be within the allowable range.
Attaching a load beyond the allowable overhang length may generate vibration or abnormal
noise.
6. Do not attempt to apply a rotary torque the rod type.
Doing so may damage the internal component such as the rod stopper, and may result in an
operation failure.
7. Back and forth operation in short distance may wear out the oil film of the
grease.
If the actuator is moved back and forth continuously over a short distance of 30 mm or less,
grease film may run out. As a guide, move the actuator 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
actuator with the grease worn out may cause malfunction. If it is extreme, flaking may occur on
the guide.
