Embedded fieldbus
Feedback from the drive – EFB
Pre-defined feedback
Inputs to the controller (drive outputs) have pre-defined meanings established by the
protocol. This feedback does not require drive configuration. The following table lists
a sample of feedback data. For a complete listing, see input word/point/object
listings in the technical data for the appropriate protocol starting on page
197 .
Note: With Modbus, any parameter can be accessed using the format: 4 followed by
the parameter number.
Mailbox read/write
The ACQ550 provides a “Mailbox” function to access parameters that have not been
pre-defined by the protocol. Using mailbox, any drive parameter can be identified
and read. Mailbox can also be used to adjust parameter settings by writing a value to
any parameter identified. The following table describes the use of this function.
1. As noted above, Modbus provides direct access to all parameters using the format: 4 followed by
the parameter number.

Mailbox
Parameter Enter the number of the drive parameter to
access. Does not apply. AV25
Mailbox
Data Contains the parameter value after a read, or
enter the desired parameter value for a write. AV26
Mailbox
Read A binary value triggers a read – the value of the
“Mailbox Parameter” appears in “Mailbox data”. BV15
Mailbox
Write A binary value triggers a write – the drive value
for the “Mailbox Parameter” changes to the value
in “Mailbox data”. BV16
