Maintenance and Inspection Precautions
When you adjust the gain during system commissioning, use a
measuring instrument to monitor the torque waveform and speed
waveform and confirm that there is no vibration.
If a high gain causes vibration, the Servomotor will be damaged
quickly.
Do not frequently turn the power supply ON and OFF. After you
have started actual operation, allow at least one hour between
turning the power supply ON and OFF (as a guideline).
Do not use the product in applications that require the power
supply to be turned ON and OFF frequently.
The elements in the SERVOPACK will deteriorate quickly.
An alarm or warning may occur if communications are performed
with the host controller while the SigmaWin+ or Digital Operator
is operating.
If an alarm or warning occurs, it may interrupt the current process
and stop the system.
After you complete trial operation of the machine and facilities,
use the SigmaWin+ to back up the settings of the SERVOPACK
parameters. You can use them to reset the parameters after SER-
VOPACK replacement.
If you do not copy backed up parameter settings, normal operation
may not be possible after a faulty SERVOPACK is replaced, possibly
resulting in machine or equipment damage.
Do not change any wiring while power is being supplied.
There is a risk of electric shock or injury.
Wiring and inspections must be performed only by qualified engi-
neers.
There is a risk of electric shock or product failure.
