Safety Information
The following conventions are used to indicate precautions in this manual. Failure to heed these precautions can
result in serious or possibly even fatal injury or damage to the products or to related equipment and systems.
Notes for Safe Operation
Read these instructions thoroughly before checking products on delivery, storage and transportation, installation,
wiring, operation and inspection, and disposal of the AC SERVOPACK.
Indicates precautions that, if not heeded, could possibly result in loss of life or seri-
ous injury.
Indicates precautions that, if not heeded, could result in relatively serious or minor
injury, damage to the product, or faulty operation.
In some situations, the precautions indicated could have serious consequences if not
heeded.
Indicates prohibited actions that must not be performed. For example, this symbol
would be used as follows to indicate that fire is prohibited: .
Indicates compulsory actions that must be performed. For example, this symbol
would be used as follows to indicate that grounding is compulsory: .
• Be sure to correctly connect the SERVOPACK connectors, CNA and CNB.
Incorrect wiring may result in electric shock, injury, or damage to the equipment. For the wiring
method, refer to 3.8 Wiring the Power Supply/Regenerative Unit Connector (CNA) and 3.9 Wiring
the Servomotor Main Circuit Cable Connector (CNB).
• Make sure that the emergency-stop circuit turns OFF the Servo ON signal and the power
supply of the main circuit when the EMG (emergency stop) signal turns ON.
Because of residual voltage, the servomotor rotates for a few seconds after the power supply has
turned OFF. This may result in injury or damage to the equipment. Make sure that the EMG means
the stop of the motor rotation.
• 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. Also, design the circuit's power supply to be automatically cut off if
/S-ON signal is OFF, and an emergency stop occurs at the same 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.
