8-2-3 RTEX Update_Counter error warning (WngC2h)
This warning will occur when the total No. of updates of Update_Counter does not reach the setting of Pr.7.28
(RTEX_Update_Counter error warning setting.)
When the setting of Pr.7.28 is 0 or 1, or when bit 11 of Pr.6.38 (Attribute C) is 0, this warning is invalid.
This warning indicates that updating cycle of the host controller and that of the servo driver are different with each other.
Mismatched communication cycles will cause detection error.
Cause
• Total number of updates of Update_Counter does not reach the setting of
Pr.7.28 (RTEX_Update_Counter error warning setting).
Detecting timing
• When RTEX communication status is RUNNING.
• When synchronization between the communication and servo is established.
• When received data is read at the command update cycle.
Internal process upon
detecting error
• Capture the received data as it is.
• RTEX communication keeps RUNNING status.
• Synchronization between communication and servo is kept established.
▪
Because the communication continues, if the normal reception is possible
after occurrence of warning, commands such as alarm clear can be received.
Action
• Check to see that the host controller and driver are normally setting cycles.
• When the communication cycle to command updating cycle ratio is 1:1 and
Update_Counter is not used, this warning is disabled.
Warning clearing
procedure after removal
of cause
• Disable this warning and execute alarm clear.
• Execute alarm clear command or the power reset or reset command to reboot
the system.
