During Use & maintenance
CAUTION
Perform the wiring work and inspection using
specialized technicians.
Perform the wiring after the product installation.
Failure to do so may lead to electric shock.
Do not perform any work with wet hands.
Doing so may lead to electric shock.
When performing the wiring work and inspection,
turn the power supply OFF and wait five minutes or
more before checking the voltage with a tester or
other equipment.
Failure to do so may lead to electric shock.
Do not attach or remove any wiring or connectors
with the power supply turned on.
Doing so may risk malfunction, failure, and electric shock.
When extending the cable, use a lead wire with a
diameter for maximum allowable current of 4 A.
A voltage drop may lead to malfunction and a decrease in
thrust as well as heat buildup and a reduced product
lifespan.
Do not connect the product's communication
connector to other devices.
Doing so may cause failure or damage.
Perform a periodic inspection two to three times a
year to check that the product is operating normally.
Refer to the Instruction Manual for details.
Routinely resupply the grease at intervals of about
100 km. However, because the interval will differ
depending on the use conditions, it is
recommended that the resupply interval be decided
during the initial inspection.
If the product fails (anomalous heat buildup, smoke
emission, strange odors, strange sounds, or
vibrations, etc. occur), immediately shut off the
power supply. Failure to do so may lead to fire due
to product damage and the continuous flow of
current.
The servo will not immediately stop when it is
turned OFF (including an emergency machine stop,
alarms) due to the added gravity and inertia. Be
sure to perform these operations in a balanced
state without any gravity or inertia applied or check
the safety before proceeding.
Be sure to turn off the power supply to this product
before performing maintenance, inspection, and
repairs. Warn other third parties in the surrounding
area so that they do not carelessly turn on the
power supply or perform any operations.
When disposing of the product, follow all laws
concerning waste processing and cleaning, and be
sure to consign the processing to a specialized
waste management service company.
The circuit board inside the product has capacitors
connected in between the circuits and the metal
body to prevent damage due to static electricity.
For this reason, voltage endurance and insulation
resistance tests should not be performed on the
equipment that the product is mounted to.
Performing such tests will damage the product.
Disconnect the product first if such equipment
testing is required.
When performing electric welding on the equipment
that the product is mounted to, remove all ground
wire connections to this product. If the connections
are not removed, the product may be damaged by
the welding current, excessively high voltage during
welding, or the surge voltage.
Set the flatness of the installation surface for the
rod to 0.1 mm or less and do not apply any twisting
or bending stresses to the product.
CAUTION
2. ECPT Controller
An excessive deviation (accumulated pulse) may
occur during pressing operations. If the torque
limiting is released under these conditions, it may
trigger sudden, uncontrolled movements. Be sure
to turn the servo off or clear the deviation.
Do not issue stop instructions while the product is
accelerating or decelerating. Doing so may result in
a dangerous change in speed (acceleration).
WARNING
Do not issue instructions which are smaller than
the minimum encoder resolution or the repeat
positioning precision. Doing so may prevent proper
positioning control in some cases.
