With bit combinations A, B and C, 8 different drive parameter sets can be
selected.
The following assignment applies:

The switchable drive parameters are as follows:
● Current setpoint filters (lowpass, bandstop); for adaptation to the
mechanic system
● 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:
DB390x DBX4001.0 to 2 (active drive parameter set).
Drive parameter switchover can be used, for example, for the following:
● To change the gear stage
● To change over the measuring circuit
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 stationary at zero speed (especially when the axis is
stationary).

Speed controller integrator disable
Signal(s) to drive (PLC → NCK)
Signal(s) updated: Cyclic
For the drive, the interface signal is used to disable the speed controller
integrator. The speed controller is thus changed over from a PI to a P con‐
troller.
Note:
If the speed controller integrator disable is activated, compensation opera‐
tions might take place in certain applications (e.g. if the integrator was al‐
ready holding a load while stationary).
The drive acknowledges the integrator disable:
DB390x DBX4001.6 (speed controller integrator disabled)
The integrator of the speed controller is enabled.
