Manufacturer Specific Objects
This section describes objects specific to OMNUC G5-series Servo Drives with built-in
EtherCAT communications. OMNUC G5-series Servo Drive parameters (Pn@@@) are
allocated to objects 3000 to 3999 hex. Index 3@@@ hex corresponds to OMNUC G5-series
Servo Drive parameter Pn@@@. For example, object 3504 hex is the same as parameter
Pn504.
For details on servo parameters, refer to Chapter 9 Details on Servo Parameter Objects.
Precautions for Correct Use
Pn@@@ uses decimal numbers but object 3 @@@ is a hexadecimal number.
 This object clears the contents of Diagnosis history (10F3 hex).
 This function can be executed by writing 6c63 6861 hex using SDO mailbox communications.
 The error history is saved in the EEPROM. If there is a Control Power Supply Undervoltage Error
(Error 11.0), you cannot make write access to the EEPROM. This means that the diagnosis history
cannot be cleared.
 In the following cases, an ABORT code is returned.
Writing with CompleteAccess.
Writing a value other than 6c63 6861 hex.
Writing when there is a Control Power Supply Undervoltage Error (Error 11.0).
 This object sets the number of times communications errors can occur consecutively before being
detected as an error.
 It can be set to between 0 and 15. The detection value will be set to one value higher than the set
value.
Reference
The default setting is 1, i.e., an error is detected when two communications errors occur
consecutively.
