Generic Profile Technical Data
Overview
The generic profile aims to fulfill the industry-standard drive
profile for each protocol (e.g. PROFIdrive for PROFIBUS, AC/
DC Drive for DeviceNet) .
Control Word
As described earlier in Control interface the CONTROL WORD
is the principal means for controlling the drive from a fieldbus
system. For specific CONTROL WORD content, see the user’s
manual provided with the FBA module .
Status Word
As described earlier in Control interface, the contents of the
STATUS WORD is status information, sent by the drive to the
master station. For specific STATUS WORD content, see the
user’s manual provided with the FBA module .
Reference
As described earlier in Control interface, the REFERENCE
word is a speed or frequency reference .
NOTE:
REF2 is not supported by the Generic Drive profiles.
Reference Scaling
REFERENCE scaling is fieldbus type specific. However, at the
drive, the meaning of a 100% REFERENCE value is fixed as
described in the table below . For a detailed description on the
range and scaling of the REFERENCE, see the user’s manual
supplied with the FBA module .

-100% = -(par . 9907)
0 = 0
+100 = (par . 9907)
Final reference limited by
1104/1105 .
Actual motor speed limited by
2007/2008 (frequency)
Actual Values
As described earlier in Control interface, Actual Values are
words containing drive values .
Actual Value Scaling
For Actual Values, scale the feedback integer using the
parameter’s resolution . (See Complete parameter descriptions
section for parameter resolutions .) For example:
Feedback
Integer
Parameter
Resolution
(Feedback Integer)
×
(Parameter
Resolution) = Scaled Value
1
0 .1 mA
1
×
0 .1 mA = 0 .1 mA
10
0 .1%
10
×
0 .1% = 1%
Where parameters are in percent, the Complete parameter
descriptions section specifies what parameter corresponds to
100% . In such cases, to convert from percent to engineering
units, multiply by the value of the parameter that defines 100%
and divide by 100% . For example:
Feedback
Integer
Parameter
Resolution
Value of the
Parameter
that defines
100%
(Feedback Integer)

(Parameter

(Value of 100% Ref .)

1 . Assuming, for the sake of this example, that the Actual
Value uses parameter 9908 MOT NOM SPEED as the
100% reference, and that 9908 = 1500 rpm .
2 . Assuming, for the sake of this example, that the Actual
Value uses parameter 9907 MOT NOM FREQ as the
100% reference, and that 9907 = 500 Hz .
