Figure 1: Current controller step response
DC bus monitoring
In special applications, e.g. when shafts with a high mass are strongly accelerated or decelerated, the
intermediate circuit voltage (DC bus voltage) may break down or become too high. If the intermediate
circuit voltage becomes to high (overvoltage > 70 V), the DUET_FL servo positioning controller will be
shut down. This is a safety function and cannot be parametrized.
Intermediate circuit voltages that are too low can cause an error if this is configured accordingly by the
user.
The menu can be activated under Parameters/Device parameters/DC bus monitoring .
The field Rated DC-bus voltage shows the voltage for which the power stage is rated. This value
cannot be changed.
In the field Undervoltage detection , you can define the response threshold below which the voltage
has to fall so that the controller detects an undervoltage. Depending on the power supply unit used, a
normal value would be 50%…70% of the rated DC bus voltage.
