Safety Precautions
This section describes important precautions that must be followed during storage,
transportation, installation, wiring, operation, maintenance, inspection, and disposal.
Be sure to always observe these precautions thoroughly.
WARNING
• Never touch any rotating servomotor parts during operation.
Failure to observe this warning may result in injury.
• Before starting operation with a machine connected, make sure that an
emergency stop can be applied at any time.
Failure to observe this warning may result in injury or damage to the equipment.
• Never touch the inside of the SERVOPACKs.
Failure to observe this warning may result in electric shock.
• Immediately after the power is turned OFF or after a voltage resistance
test, do not touch terminals.
Residual voltage may cause electric shock.
• Follow the procedures and instructions provided in the manuals for the
products being used in the trial operation.
Failure to do so may result not only in faulty operation and damage to equipment,
but also in personal injury.
• The multiturn limit value need not be changed except for special applica-
tions.
Changing it inappropriately or unintentionally can be dangerous.
• If the Multiturn Limit Disagreement alarm occurs, check the setting of
parameter Pn205 in the SERVOPACK to be sure that it is correct.
If Fn013 is executed when an incorrect value is set in Pn205, an incorrect value
will be set in the encoder. The alarm will disappear even if an incorrect value is set,
but incorrect positions will be detected, resulting in a dangerous situation where
the machine will move to unexpected positions.
• Do not remove the cables or connectors from the SERVOPACK while the
power is ON.
Failure to observe this warning may result in electric shock.
• Do not damage, pull, exert excessive force on, or place heavy objects on
the cables.
Failure to observe this warning may result in electric shock, stopping operation of
the product, or fire.
• Do not modify the product.
Failure to observe this warning may result in injury, damage to the equipment, or
fire.
• Provide appropriate braking devices on the machine side to ensure safety.
The holding brake on a servomotor with a brake is not a braking device for
ensuring safety.
Failure to observe this warning may result in injury.
• Do not come close to the machine immediately after resetting an instanta-
neous power interruption to avoid an unexpected restart. Take appropriate
measures to ensure safety against an unexpected restart.
Failure to observe this warning may result in injury.
