The input mappings are PNU968 and PNU1001 and the output mappings are PNU967
and PNU1003.
Pr S.02.001 will display 5.00.968 (PNU968), Pr S.02.002 will display 5.01.001
(PNU1001), Pr S.03.001 will display 5.00.967 (PNU967) and Pr S.03.002 will display
5.01.003 (PNU1003).
Table 6.5 shows all the possible values of the Telegram selection (Pr S.01.008).
Table 6.5 All values for Telegram selection
As shown in Table 6.5, only Auto, Custom and STD Tel 1 are available when the
SI-PROFIBUS module is connected to a Unidrive M and compatibility mode
(Pr S.01.031) is set to Auto detect. If any other telegram selection is made, the drive will
display an alarm of Invalid IN map and Invalid OUT map (see Section 10 - Diagnostics
for more information).
See section 14 Legacy features for more information on the full range of Telegram
selection (Pr S.01.008) when in Unidrive SP compatibility mode.
The network loss detection feature provides a method which detects whether the
communication to the master is still present. The SI-PROFIBUS resets an internal timer
when a valid message is received from the SI-PROFIBUS network, if a message is not
received within the specified period, network loss is detected.
The network loss detection can be disabled by setting the value of Pr S.01.010 to 0.
Users must then take adequate precautions in the event of a failure of the PROFIBUS
network.
