The CA N-8x
23 doesn’t support the SYNC generation, therefore 29-bit ID, bit 30 and bit
31 are always in 0.
4. The object with index 0x1008, 0x1009 and 0x100A records the CAN-8423 product
information. When interpreting these objects, the ASCII table will be needed.
5. The range of t he 0x 100c is from 0 to 32767 in CA N-8x23. For more information of t he
object with index 0x100C and 0x100D, please refer to the section 5.4.2.
6. The object 0x1010/0x1011 supports the saving/restoring of parameters in EEPROM.
There 3 parameter groups are distinguished:
Subindex 1 saves/restores all PDO communication and I/O application parameters.
Subindex 2 saves/restores all PDO communication parameters.
Subindex 3 saves/restores all I/ O application parameters (ex: safe value, A I invert er,
PWM setting, and so on).
7. For the object with index 0x1014, please refer to the section 5.3.1.
8. The object with index 0x1015 stores the inhibit time period bet ween two EMCY message.
The function of this object is similar to the P DO communication object with sub-index 04.
It is valid for avoiding the large loading on the CA N bus when transmitting a lot of EMCY
messages. This parameter range is from 0 to 32767 for the CAN-8x23, and the unit of
EMCY inhibit time is ms.
