CAUTION
Do not move the movable section of the product with external force and do not use the
product in an application that requires the movable section to decelerate suddenly.
A malfunction or damage may occur due to regenerative currents.
Do not subject the product to external force when returning to the origin.
The origin may not be recognized correctly.
Do not put dents and scratches on the movable section.
An operation fault may occur.
Do not subject the movable section to impact.
Leave a margin for the transfer load since the product life changes depending on the transfer
load and the environment.
If vibrations are generated, change the set speed and use the product at a speed that does
not generate vibrations.
Depending on the conditions of use, vibrations may be generated during an operation even when
the product is used within the operation speed range.
Provide the required pressing force with a sufficient margin to ensure operation.
The pressing force and the maximum current values given in "1.5 Specifications" are provided as a
guide. Variation in the motor torque may cause errors even when the setting values are the same.
Do not turn off the servo while gravity or force of inertia is applied.
Turn off the servo in an equilibrium state where no gravity and force of inertia are applied or after
safety is ensured.
Do not stop the product while it is accelerating or decelerating.
It may lead to a change in speed (acceleration) and cause a risk.
Do not insert fingers or an object into the opening of the product.
An injury or product damage may occur.
When replacing either the actuator or the controller in a combination, make sure to check the
program and parameters before operating the product.
An unexpected operation may lead to an accident.
Do not turn the power on and off frequently.
Elements in the controller may become damaged.
Do not use a load that does not fall within the specified range.
If the load falls outside the range, an excessive uneven load applied to the guide section may
cause rattling in the guide section, deteriorate accuracy, and adversely affect service life.
To use the product for pressing, make sure to perform the
"
pressing operation
"
.
If external contact is made during positioning operation and within the positioning range, a
significant energy is generated and damage may occur.
Set
the target position for the pressing operation
to a position that is at least 1 deg less than the
external contact position (to allow for backlash).
When operating the product without supplying power, make sure to use the manual operation
plate.
The table will not move even if external force is applied since a self-locking mechanism using
gears is employed.
•
If a sudden stop occurs during table rotation due to an emergency stop or inching, a load
torque that exceeds the theoretical value can be generated depending on the backlash,
operating conditions, and loading conditions.
•
There is backlash since a worm gear is used in the drive system. Depending on the operating
conditions and loading conditions, it can cause residual vibration or increase positioning time.
•
When stop accuracy is required, stop the product using the external stopper and complete the
positioning by performing the pressing operation.
