AC Servomotors/Servo Drives 1S-series Instruction Manual
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.
Fully check the shaft when you reset a brake interlock from PC tool.
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.
Install a stopping device on the machine to ensure safety.
The holding brake is not a stopping device to ensure safety.
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.
Injury or malfunction 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.
When a difference between a position indicated by the Servo Drive before the power supply
OFF and a position after the power supply ON is one rotation or more, check that devices
are placed in appropriate areas.
Immediately stop the operation and cut off the power supply when unusual smell, noise,
smoking, abnormal heat generation, or vibration occurs.
The Servo Drive or Servomotor may be damaged or burn.
Cut off the power supply during maintenance. Not doing so may cause an electric shock.
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.
