Detailed Description
2.1 Various interface signals and functions (A2)
Basic logic functions: NC/PLC interface signals (Z1)

DB31, ...
DBX21.0 - DBX21.2
Drive parameter set selection A, B, C
Edge evaluation: no Signal(s) updated: cyclic
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/SINUMERIK 810D.
The following assignment applies:

The switchable drive parameters are as follows:
• Current setpoint filters (lowpass, bandstop); for adaptation to the mechanics
• Motor speed normalization
• Speed controller parameters
• Speed setpoint filter
• Speed monitoring data
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
example(s)
Drive parameter switchover can be used for the following:
• Changing the gear stage
• Changing-over the measuring circuit
Special cases,
errors, ....
In principle it is possible to switch over drive parameter sets at any time. However, as torque jumps
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).
