Emergency object – EMERGENCY
When IFD9503 detects an internal error, it will send an EMCY message to the CANopen bus.

Error register
The value in the error register will be mapped to index address H’1001 in the object
dictionary. Value = 0 indicates that no error occurs. Value = 1 indicates that a general error
takes place. Value = H’80 indicates that an internal error in the equipment occurs.
y
Emergency error code
Internal communication error
This error indicates the communication error between IFD9503 and AC motor drive (e.g.
communicate failure). When such error occurs, the emergency error code will be H’8101,
and the value in the error register will become 1.
CANopen bus communication error
This error indicates the communication error between CANopen master and IFD9503
slave (e.g. master disconnection). When such error occurs, the emergency error code
will be H’8130, and the value in the error register will become 1.
Insufficient length of PDO data
This error indicates that the length of Receive PDO data actually sent out is shorter than
the set data length. When such error occurs, the emergency error code will be H’8210,
and the value in the error register will become 1.
Internal error in the equipment
This error indicates the error taken place inside the AC motor drive (e.g. AC motor drive
in low voltage). When such error occurs, the emergency error code will be H’FFXX (XX
refers to the error code of the AC motor drive), and the value in the error register will
become H’80. After the error is eliminated, the emergency error code will become
H’0000.
Eliminating error
When an error is eliminated, the emergency error code will become H’0000.
Explanation
Take the IFD9503 slave of node ID = 6 as the object and compare the EMERGENGY
messages sent out by IFD9503 in different error conditions.
