5-7 Emergency Messages
When an error or warning occurs in a 1S-series Servo Drive, an emergency message is sent to the
master through SDO communications. An emergency message is not sent for a communications error.
You can select whether or not to send emergency messages in Diagnosis History (10F3 hex).
When the power supply is turned ON, Diagnosis History – Flags (10F3-05 hex) is set to 0 ( not
notify ).
To send emergency messages, set the least significant bit of Diagnosis History – Flags (10F3-05 hex)
to 1 every time the power is turned ON.
An emergency message consists of 8-byte data.
Note For details on errors and warnings of the Servo Drive, refer to Section 12 Troubleshooting .
