Figure 5-16 DDS switchover in the inverter
The drive data sets are switched over using parameters P0820 and P0821. Parameters
P0820 and P0821 are interlinked to control commands, e.g. the digital inputs of the inverter,
using BICO technology.
Note
Drive data sets can only be changed over in the "ready for operation" state. The switchover
time is approx. 50 ms.
Exceptions: The ramp-function generator parameters, the ramp-down time for OFF3, and the
speed controller gain can be switched during operation.
