The scaled references are shown by parameters 3.5 FB A reference 1 and 3.6 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
50.7 FBA A
actual 1 type and 50.8 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 50.7 FBA A actual 1 type and 50.8
FBA A actual 2 type .
