tables below and must be checked first and adjusted where necessary. You can adjust
the parameters via a drive control panel, a PC tool or a web user interface.
Note:
•
Not all drives display descriptive names for the configuration parameters.
•
The new parameter settings take effect only when you power up the module the
next time or when you activate the fieldbus adapter refresh parameter 51.27 FBA
A par refresh.
FMBT-21 configuration parameters – group A (group 1)
Note: The actual parameter group number depends on the drive type. Group A (group
1) corresponds to:
•
parameter group 51 in ACS380, ACS480, ACS580, ACH580 and ACQ580.
•
parameter group is typically 51/54 (group 151/154 in some variants) in ACS880 if
the adapter is installed as fieldbus adapter A/B.
No.

Description
01
FBA type
Read-only. Shows the fieldbus adapter type as detected by the
drive. The value cannot be adjusted by the user.
If the value is 0 = None, the communication between the drive and
the module has not been established.
02
Protocol/profile
Selects the application protocol and communication profile for
the network connection.
The selections available for Modbus communication are listed
