Caution in Handling
1. Make sure to follow the usage condition, environment and specification range of the
product.
In case it is not secured, it may cause a drop in performance or malfunction of the product.
2. Do not attempt to have any handling or operation that is not stated in this Instruction
manual.
3. It is recommended to apply our products for the wiring between the actuator and the
controller.
4. 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.
5. Set the allowable moment within the allowable range.
If the robot is operated under a load equal to or greater than the allowable moment, abnormal noise
or vibration, failure, or shorter life may result.If it is extreme, flaking may occur on the guide.
6. Set the overhang load length within the allowable range.
Attaching a load with an overhang load length above the allowable range may cause vibration and
abnormal noise.
7. If back and forth operations are performed repeatedly in short distance, it may wear
out the film of grease.
Continuous back and forth operation within a distance less than 30mm may cause wear of grease.
As a reference, have approximately 5 cycles of back and forth operation in a distance more than
50mm in every 5,000 to 10,000 cycles to regenerate the oil film. Keep using the actuator with the
grease worn out may cause malfunction. If it is extreme, flaking may occur on the guide.
8. The position will slightly move only in the first time of turning the servo on after the
power is supplied.
In the first time to turn the servo on after the power is supplied only, position adjustment operation
will be conducted due to the characteristics of the stepper motor. For this reason, the position will
slightly move. The maximum amount of move is 0.025 × lead length [mm].
Pay attention not to have peripheral equipment interfere.
9. Turn on the servo after making sure the slider 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 pole non-confirmation error or excitation detection error may occur. Set the
slider away from the mechanical end.
10. Pressing operation cannot be performed.
11. 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.
