5 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 servo drives.
• 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 remove the terminal cover while the power is ON.
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 noted in the relevant
User’s Manual.
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 multi-turn limit value must be changed only for special applications.
Changing it inappropriately or unintentionally can be dangerous.
• If the Multi-turn 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 terminal cover, cables, connectors, or optional items while the power is
ON.
Failure to observe this warning may result in electric shock.
• Connect the ground terminal to electrical codes (ground resistance: 100 Ω or less).
Improper grounding may result in electric shock or fire.
• Installation, disassembly, or repair must be performed only by authorized personnel.
Failure to observe this warning may result in electric shock or injury.
