ABB ACS880-104

Fieldbus control through a fieldbus adapter 635
The references are scaled as defined by parameters 46.01…46.07; which scaling is
in use depends on the setting of 50.04 FBA A ref1 type and 50.05 FBA A ref2 type.
The scaled references are shown by parameters 03.05 FB A reference 1 and 03.06
FB A reference 2.
 Actual values
Actual values are 16-bit words containing information on the operation of the drive.
The types of the monitored signals are selected by parameters 50.07 FBA A actual 1
type and 50.08 FBA A actual 2 type.
Debugging the network words
If parameter 50.12 FBA A debug mode is set to Fast, the actual values sent to the
fieldbus are displayed by 50.17 FBA A actual value 1 and 50.18 FBA A actual value
2.
Scaling of actual values
Note: The scalings described below are for the ABB Drives communication profile.
Fieldbus-specific communication profiles may use different scalings. For more
information, see the manual of the fieldbus adapter.
The actual values are scaled as defined by parameters 46.01…46.04; which scaling
is in use depends on the setting of parameters 50.07 FBA A actual 1 type and 50.08
FBA A actual 2 type.
