Switchover between different settings
Overview
In several applications, the converter must be able to be operated with different settings.
Example:
Different motors are operated on one converter. Depending on the particular motor, the
converter must operate with the associated motor data and the appropriate ramp-function
generator.
Function description
Drive Data Sets (DDS)
Your can parameterize several converter functions differently and then switch over between
the different settings.
Note
You can only switch over the motor data of the drive data sets in the "ready" state with the motor
switched off. The switchover time is approx. 50 ms.
If you do not switch over the motor data together with the drive data sets (i.e. same motor
number in p0826), then the drive data sets can also be switched over in operation.
The associated parameters are indexed (index 0 or 1). Via control commands select one of
the two indices and therefore one of the two saved settings.
The settings in the converter with the same index are known as drive data set.
