ABB ACS880-104

76 Program features
The communication uses data sets 10…33. The contents of the data sets are freely
configurable, but data set 10 typically contains the control word and one or two
references, while data set 11 returns the status word and selected actual values. For
ModuleBus communication, the ACS880 can be set up as a “standard drive” or an
“engineered drive” by parameter 60.50 DDCS controller drive type. ModuleBus
communication uses data sets 1…4 with a “standard drive” and data sets 10…33 with
an “engineered drive”.
The word that is defined as the control word is internally connected to the drive logic;
the coding of the bits is as presented in section Contents of the fieldbus Control word
(ABB Drives profile) (page 637). Likewise, the coding of the status word is as shown
in section Contents of the fieldbus Status word (ABB Drives profile) (page 638).
By default, data sets 32 and 33 are dedicated for the mailbox service, which enables
the setting or inquiry of parameter values as follows:
By parameter 60.64 Mailbox dataset selection, data sets 24 and 25 can be selected
instead of data sets 32 and 33.
The update intervals of the data sets are as follows:
• Data sets 10…11: 2 ms
• Data sets 12…13: 4 ms
• Data sets 14…17: 10 ms
• Data sets 18…25, 32, 33: 100 ms.
