Read this manual thoroughly before checking products on delivery, storage and transportation,
installation, wiring, operation and inspection, and disposal of the NS115 Module.
• Never touch any motor rotating 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 panel 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

Malfunctions that occur after the servomotor is connected to the machine not only damage the machine, but
may also cause an accident resulting in death or injury.
• 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.
• Do not damage, press, pinch, 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.
• Do not modify the product.
Failure to observe this warning may result in injury or damage to the product.
• 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.
