Notes for Safe Operation
Read this manual thoroughly before checking products on delivery, storage and transportation, installation,
wiring, operation and inspection, and disposal of the AC servodrive.
• Never touch any rotating motor parts while the motor is running.
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.
• Never touch the inside of the SERVOPACKs.
Failure to observe this warning may result in electric shock.
• Do not touch terminals for five minutes after the power is turned OFF.
Residual voltage may cause electric shock.
• Do not touch terminals for five minutes after voltage resistance test.
Residual voltage may cause electric shock.
• Follow the procedures and instructions for trial operation precisely as described in this man-
ual.
Malfunctions that occur after the servomotor is connected to the equipment not only damage the
equipment, but may also cause an accident resulting in death or injury.
• The multiturn limit value must be changed only for special applications.
Changing it inappropriately or unintentionally can be dangerous.
• If the Multiturn Limit Disagreement alarm (A.CC) 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 front cover, cables, connectors, or optional items while the power is ON.
Failure to observe this warning may result in electric shock.
• Do not damage, press, exert excessive force or place heavy objects on the cables.
Failure to observe this warning may result in electric shock, stopping operation of the product, or
burning.
• Provide an appropriate stopping device on the machine side to ensure safety. A holding
brake for a servomotor with brake is not a stopping device for ensuring safety.
Failure to observe this warning may result in injury.
• Do not come close to the machine immediately after resetting momentary power loss to
avoid an unexpected restart. Take appropriate measures to ensure safety against an
unexpected restart.
Failure to observe this warning may result in injury.
•
Connect the ground terminal to electrical codes (ground resistance: 100
Ω
or less).
Improper grounding may result in electric shock or fire.
