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.
• If you have a pacemaker or any other electronic medical device, do not go near the magnetic
way of the linear servomotor.
Failure to observe this warning may result in the malfunction of the medical device.
• Be sure to use nonmagnetic tools when installing or working close to the linear servomotor.
(Example: a beryllium-copper alloy hexagonal wrench set, made by NGK Insulators, Ltd.)
• If starting an operation with the linear servomotor in a machine, set the linear servomotor to
always allow emergency stops.
Failure to observe this warning may result in injury.
• Never touch the linear servomotor or machinery during operation.
Failure to observe this warning may result in injury.
• Before wiring, install the SERVOPACK and the linear servomotor.
Failure to observe this warning may result in electric shock.
• Do not operate switches with wet hands.
Failure to observe this warning may result in electric shock.
• 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.
• Make sure that the main circuit power cable, the control power cable, and the linear
servomotor main circuit cable are wired correctly.
Failure to observe this warning may result in damage to the SERVOPACK.
• 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 SGDH SERVOPACK supports both AC and DC power. If DC power is supplied to the
SERVOPACK without setting Pn001=n.†1†† (DC power input), the internal components
of the SERVOPACK will burn and may result in fire or serious damage.
Before using a DC power supply, be sure to check the parameter Pn001 setting.
• 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.
