DBX21.0 - DBX21.2 Drive parameter set selection A, B, C
Edge evaluation: No
Meaning With bit combinations A, B and C it is possible to select 8 different drive parameter sets for the
digital drives SIMODRIVE 611D/611U.
The following assignment applies:
The switchable drive parameters are as follows:
•
•
•
•
•
As soon as the new drive parameter becomes effective, the drive signals this to the PLC using the
interface signals:
DB31, ... DBX93.0, 1 and 2 (active parameter set).
Application Drive parameter switchover can be used for the following:
example(s)
•
•
Special cases, In principle it is possible to switch over drive parameter sets at any time. However, as torque jumps
errors, .... can occur when switching over speed controller parameters and motor speed normalization,
parameters should only be switched over when in the zero speed state (especially when the axis is
stationary).
