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
eldbussystem.Forspecic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specic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 proles.

on the range and scaling of the REFERENCE, see the user’s
manual supplied with the FBA module.

Speed
-100% = -(par. 9908)
0 = 0
+100 = (par. 9908)
Final reference limited by
1104/1105.
Actual motor speed limited by
2001/2002 (speed).
Frequency
-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specieswhatparametercorrespondsto
100%. In such cases, to convert from percent to engineering
units,multiplybythevalueoftheparameterthatdenes
100% and divide by 100%. For example:
Feedback

Resolution) ×
(Value of 100% Ref.)
/ 100% = Scaled Value

10 × 0.1% × 1500 RPM / 100%
= 15 rpm
100
0.1% 500 Hz
2
100 × 0.1% × 500 Hz / 100% = 50 Hz
