NOTICE!
– 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 per-
formed 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.
DANGER!
Do not change any wiring while power is being supplied.
There is a risk of electric shock or injury.
WARNING!
Wiring and inspections must be performed only by qualified engi-
neers.
There is a risk of electric shock or product failure.
CAUTION!
– Wait for at least six minutes after turning OFF the power supply
(with a SERVOPACK for a 100- VAC power supply input, wait for
at least nine minutes) and then make sure that the CHARGE indi-
cator is not lit before starting wiring or inspection work. Do not
touch the power supply terminals while the CHARGE lamp is lit
after turning OFF the power supply because high voltage may
still remain in the SERVOPACK.
There is a risk of electric shock.
– Before you replace a SERVOPACK, back up the settings of the
SERVOPACK parameters. Copy the backed up parameter set-
tings to the new SERVOPACK and confirm that they were copied
correctly.
If you do not copy backed up parameter settings or if the copy opera-
tion is not completed normally, normal operation may not be possible,
possibly resulting in machine or equipment damage.
