 Even after you shut OFF the power supply, voltage may still remain in the SERVOPACK. Do not
touch the SERVOPACK until the power indicator goes OFF.
There is a risk of electric shock.
 Before you replace a SERVOPACK, back up the SERVOPACK parameter settings and table
data. Copy the backed up parameter settings and table data to the new SERVOPACK and con-
firm that they were copied correctly.
If you do not copy backed up parameter settings and table data or if the copy operation is not com-
pleted normally, normal operation may not be possible, possibly resulting in machine or equipment
damage.
 Discharge any static electricity from your body before you touch a SERVOPACK.
There is a risk of equipment damage.
 Troubleshooting Precautions
 When an alarm occurs, remove the cause of the alarm and ensure safety. Then reset the alarm
or turn the power supply OFF and ON again to restart operation.
There is a risk of injury or machine damage.
 If the SERVO ON signal is input to the SERVOPACK and an alarm is reset, the Servomotor may
suddenly restart operation. Confirm that the system is in the SERVO OFF state and ensure
safety before you reset an alarm.
There is a risk of injury or machine damage.
 Always install a magnetic contactor or other shutoff device on the input side of the isolated 24-
VDC power supply so that the power supply can be shut OFF.
If a magnetic contactor or other shutoff device is not connected when the SERVOPACK fails, a
large current may flow, possibly resulting in fire.
 If an alarm occurs, shut OFF the power supply.
If a magnetic contactor or other shutoff device is not connected when the SERVOPACK fails, a
large current may flow, possibly resulting in fire.
 Install a ground fault detector against overloads and short-circuiting or install a molded-case
circuit breaker combined with a ground fault detector.
There is a risk of SERVOPACK failure or fire if a ground fault occurs.
