Safety Precautions
22
AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
Lock the power cable and extension cable connectors.
Not doing so may cause fire.
Operation Check
Use the Servomotor, Servo Drive and motor cable in a specified combination.
Not doing so may cause fire or equipment damage.
Usage
Do not enter the operating area during operation.
Doing so may cause injury.
Do not touch the Servo Drive radiator, Regeneration Resistor, or Servomotor while the
power is supplied or for a while after the power is turned OFF because they get hot.
Doing so may cause fire or a burn injury.
Take appropriate measures to ensure that the specified power with the rated voltage is sup-
plied. Be particularly careful in locations where the power supply is unstable.
Not doing so may cause failure.
When the power is restored after a momentary power interruption, the machine may restart
suddenly. Do not come close to the machine when restoring power.
Implement measures to ensure safety of people nearby even when the machine is
restarted.
Doing so may cause injury.
Use appropriate tools to wire terminals and connectors. Check that there is no short-circuit
before use.
Not doing so may cause electric shock.
Be sure to observe the radiator plate installation conditions that are specified in the manual.
Not doing so may cause the Servo Drive or Servomotor to burn.
If the load that exceeds the allowable range is installed, it may cause the dynamic brake to
be damaged. Be sure to use the appropriate load. For the selection of the appropriate load,
refer to 4-5 Adjustment for Large Load Inertia on page 4-78.
Not doing so may cause the Servo Drive to be damaged.
The dynamic brake is intended for the stop at the time of an error and therefore it has a
short-time rating.
If the dynamic brake is activated, provide an interval of 3 minutes or more before the next
activation to prevent a circuit failure and burning of the Dynamic Brake Resistor.
