AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
• 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.
• Do not adjust or set parameters to extreme values, because it will make the operation unstable. Injury
may result.
• Ensure that the Servomotor has a sufficient rigidity. Equipment damage or malfunction may result.
• If a problem occurs in serial communications or the computer during a test operation, you have no
means to stop the Servomotor.
Connect an externally installed emergency stop switch, etc. to the Error Stop Input of the general-pur-
pose input so that the Servomotor can be stopped without fail.
• When using the Servomotor with key, run the Servomotor in a state in which the key cannot jump out
of the shaft.
Not doing so may result in hurting people around the equipment due to the jumping key.
• Before operating the Servo Drive in an actual environment, check if it operates correctly based on the
newly set parameters. Equipment damage may result.
• Do not adjust or set parameters to extreme values, because it will make the operation unstable. Injury
may result.
• Do not drive the Servomotor by the use of an external drive source. Fire may result.
• Check the newly set parameters for proper execution before actually using them.
• Tighten the mounting screws, terminal block screws, and cable screws for the Servo Drive, Servomo-
tor, 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.
• Do not place flammable materials near the Servomotor, Servo Drive, or peripheral equipment. 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.
• If the Servo Drive fails, cut off the power supply to the Servo Drive at the power supply. Fire may
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.
