Safety Precautions
AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
• Tighten the mounting screws, terminal block screws, cable screws and shield clamp screws for the
Servo Drive, Servomotor, and peripheral equipment to the specified torque. Failure may result.
• Install a stopping device on the machine to ensure safety.
The holding brake is not a stopping device to ensure safety. Injury may result.
• Install an immediate stop device externally to the machine so that the operation can be stopped and
the power supply is cut off immediately. Injury may result.
• Conduct a test operation after confirming that the equipment is not affected. Equipment damage may
result.
• Do not use the built-in brake of the Servomotor for normal braking operation. Failure may result.
• After an earthquake, be sure to conduct safety checks. Electric shock, injury, or fire may result.
• Connect an emergency stop (immediate stop) relay in series with the brake interlock output. Injury or
failure may result.
• Do not use the cable when it is laying in oil or water. Electric shock, injury, or fire may result.
• Install safety devices to prevent idling or locking of the electromagnetic brake or the gear head, or
leakage of grease from the gear head. Injury, damage, or taint damage result.
• Be sure to turn OFF the power supply when not using the Servo Drive for a prolonged period of time.
Not doing so may result in injury or malfunction.
• When constructing a system that includes safety functions, be sure you understand the relevant
safety standards and all related information in user documentation, and design the system to comply
with the standards. Injury or equipment damage may result.
• If the Servomotor is not controlled, it may not be possible to maintain the stop. To ensure safety,
install a stop device. Equipment damage or injury may result.
• Periodically run the Servomotor approximately one rotation when the oscillation operation continues
at a small angle of 45° or smaller. Servomotor failure may result.
• Immediately stop the operation and cut off the power supply when unusual smell, noise, smoking,
abnormal heat generation, or vibration occurs. Not doing so may result in Servo Drive or Servomotor
damage or burning.
• Fully check the shaft when you reset a brake interlock from PC tool.
• After replacing the Servo Drive, transfer to the new Servo Drive all data needed to resume operation,
before restarting operation. Equipment damage may result.
• Do not repair the Servo Drive by disassembling it. Electric shock or injury may result.
