Drive parameter set selection A, B, C
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).
Corresponding to .... DB31, ... DBX93.0, 1 and 2 (active drive parameter set)

Motor selection A, B
Edge evaluation: no Signal(s) updated: cyclic
Meaning The PLC can switch between 4 different motors or motor mode types using the motor selection
function.

As soon as a new motor selection is detected, the drive cancels the pulse enable (feedback signal
using the interface signal DB31, ... DBX93.3 and 4 (active motor)).
Using the motor selection, it is possible, for example, to choose mode 1 as star-connected
operation and mode 2 as delta-connection operation for the main spindle drive (MSD).
The drive signals the currently selected motor back to the PLC using the interface signals:
DB31, ... DBX93.3 and 4 (active motor).

Notice:
Before a new motor is selected, the interface signal:
