Warning status alarms for servo amplifiers
When bit 2 (SWP) of parameter No. 1807 is set to 0, if a servo amplifier is placed in the warning status, a
DS alarm is output in addition to the servo warning detail signals.
If one of the following alarms is issued, automatic operation enters the feed hold state and movements
along all controlled axes including PMC axes are decelerated to a stop. Issuing a warning status alarm
does not cause to the servo motor to be deactivated.

DS0608
SV0444
n-axis : SV INTERNAL
FAN FAILURE
Immediately after the fan stops, alarm DS0608 is
displayed and movements along axes enter the
feed hold stop state. The servo motor is kept
active for 1 minute. After that, the servo motor is
deactivated and alarm SV0444 is displayed.
DS0609
SV0601
n-axis : SV EXTERNAL
FAN FAILURE
Immediately after the fan stops, alarm DS0609 is
displayed and movements along axes enter the
feed hold stop state. When bit 2 (SWP) of
parameter No. 1807 is set to 1 after that, the alarm
display can be canceled by a reset and operation
can be restarted.
DS0610
SV0443
n-axis : SV INTERNAL
FAN FAILURE
Immediately after the fan stops, DS0610 is
displayed and movements along axes enter the
feed hold stop state. The servo motor is kept
active for 1 minute. After that, the servo motor is
deactivated and alarm SV0443 is displayed.
DS0611
SV0606
n-axis : PS EXTERNAL
FAN FAILURE
Immediately after the fan stops, DS0611 is
displayed and movements along axes enter the
feed hold stop state. When bit 2 (SWP) of
parameter No. 1807 is set to 1 after that, the alarm
display can be canceled by a reset and operation
can be restarted.

ERROR
Alarm DS0614 is displayed and movements along
axes enter the feed hold stop state. The servo
motor is kept active for fixed time. The time until
deactivation depends on where the trouble occurs
in.
After an alarm in the warning status listed in Table 18.1 (b) is issued, when the
α
i servo amplifier is
actually placed in the alarm status, the servo motor is deactivated and the number of an alarm in the alarm
status is additionally displayed.
When bit 2 (SWP) of parameter No. 1807 is set to 1, if a servo amplifier is placed in the warning status,
only the servo warning detail signals are output and no alarm in the warning status (alarm DS0608 to
DS0614) is issued. If a servo amplifier is placed in the warning status during automatic operation,
automatic operation is kept. So, decelerate the movements along axes to a stop using the servo warning
detail signals before the servo motor is deactivated. Note that if the movements along axes are not
decelerated to a stop, the servo motor is suddenly deactivated during movement along axes.
