AL128 Error occurs when reading CANopen PDO from EEPROM
Trigger condition
and causes
An error occurs when loading the default value from ROM at start-up.
All objects of CAN automatically return to the default value.
Checking methods
and corrective
actions
When PDO is receiving or sending, check if the error occurs because the
specified object reads from EEPROM.
How to clear the
alarm?
NMT: reset node or 0x6040 (fault reset).
AL129 Error occurs when writing CANopen PDO to EEPROM
Trigger condition
and causes
An error occurs when saving the current parameter value into ROM.
Checking methods
and corrective
actions
When PDO is receiving or sending, check if the error occurs because the
specified object is written to EEPROM.
How to clear the
alarm?
NMT: reset node or 0x6040 (fault reset).
AL130 Accessing address of EEPROM is out of range when using CANopen PDO
Trigger condition
and causes
The quantity of the data in the ROM is greater than the allowable space
specified by the firmware. It is probably because the firmware has been
updated, but the data in the ROM was stored by the old version of the
firmware.
Checking methods
and corrective
actions
Check if the addressing in EEPROM exceeds the range for the specified
object during PDO receiving or sending.
How to clear the
alarm?
NMT: reset node or 0x6040 (fault reset).
AL131 CRC of EEPROM calculation error occurs when using CANopen PDO
Trigger condition
and causes
The data in ROM is damaged; all CANopen objects are automatically
restored to default values.
Checking methods
and corrective
actions
Check if the specified object causes a CRC calculation error in EEPROM
when PDO is being received or sent. Usually, this alarm is caused by an
error in DSP.
How to clear the
alarm?
NMT: reset node or 0x6040 (fault reset).
AL132 Parameter is write-prohibited when using CANopen PDO
Trigger condition
and causes
When using CAN object to write data to the parameter, the parameter is
currently write-prohibited.
Checking methods
and corrective
actions
Please refer to the specified parameter description to write data to the
parameter.
