900 Alarm
* During initialization, "CF" (CF warning) may be displayed on the operation panel. Moreover, "CF" and the communication
status number are displayed alternately on the SSCNET ΙΙΙ communication status monitor. (Refer to page 48 for the
SSCNET ΙΙΙ communication status monitor.)

When the power of the servo system controller turned off after SSCNET ΙΙΙ
communication establishment.
When Pr. 499 SSCNET III operation selection = "9999" (Operation invalid mode).
When the SSCNET ΙΙΙ communication status displays "120", possible causes are as follows.
When the inverter power is on when the servo system controller power is off.
When an inverter failure or a communication error with the servo system controller
occurs. The display of the SSCNET ΙΙΙ communication status at this time is as follows:
"120"→"130"→"140"→"120"
When the servo system controller is in faulty.
When initialization has never completed after powering on the power.
During initial setting of the communication specifications
When the shaft numbers set by the servo system controller and the inverter shaft
number switch are not the same.
The display of the SSCNET ΙΙΙ communication status at this time is as follows:
"120"→"121"→"120"→"120"
When communication initialization setting has completed and the inverter is in
synchronization with the servo system controller.
During preliminary communication with the servo system controller.
During motor and encoder data communication with the servo system controller.
During initial signal data communication with the servo system controller.
During completion operation of initial data communication with the servo system controller.
Inverter alarm ("Major fault" of the inverter alarm)
Description
For example, the first shaft is indicated as 201, 301 or
401.
