Emerson 0471-0128-02 manual Network configuration objects, SM-EtherCAT network loss trip, 0x2813

Commander SK / Commander SL

The software version of the Solutions Module can be identified by looking at Pr 15.02 and Pr 15.51.

The software version takes the form of xx.yy.zz, where Pr 15.02 displays xx.yy and Pr 15.51 displays zz (e.g. for software version 01.01.00 Pr 15.02 will display 1.01 and Pr 15.51 will display 0).

Table 9.4 Network loss behavior object

0x2813	Network loss behavior
Sub-index 0:
Access: RO		Range: N/A	Size: 1 byte	Unit: N/A
Default:	2
Description:	The number of last sub-indexes in this object.

Sub-index 1: Maximum time interval

Access: RW Range: 0 to 65535 Size: 2 bytes Unit: ms

Default:0 (by default the network loss behavior is disabled)

Description: The maximum time, in ms, allowed between accesses to PDOs (read or write). If no PDO access occurs for this period, the option will start network loss handling. If a value of zero is set, no network loss handling will occur.

Sub-index 2: Trip type

Access: RW		Range: 0 to 2	Size: 1 byte	Unit: N/A
Default:	0

Description: Network loss trip type. If this value is set to 0, a network loss trip will never occur; however, a network loss will still be handled by stopping the drive and indicating a warning as previously described. If this value is set to 1, the network loss trip will occur only after the motor has been stopped according to the Fault reaction option code. If the value is set to 2, the network loss trip will occur immediately on network loss (this implies that the motor will coast).

SM-EtherCAT resets an internal timer when a valid message is received from the EtherCAT network. The network loss trip is triggered when no new messages are received before the timer times out. The SM-EtherCAT will trip the drive and the SM- EtherCAT error code parameter (Pr MM.50) will show 120.

After power-up or reset the network loss trip is not armed until one of the following events occur:

•SYNC message is received.

•RxPDO is received

Once the trip has been armed, a minimum of one of the above messages must be received or transmitted in each time period set in sub-index 2 of the Network loss behavior object (0x2813).
