4.5.1 Adding a data record for data record changeover
Introduction
The "MC_ChangeDataset" technology function can be used to perform a data
record changeover at an axis. You can create data records for velocity-controlled
axes, positioning axes and synchronization axis. Virtual axes always have only one
data record.
The data record changeover function can be used, for example, to toggle between
the motor encoder and the machine encoder, or the edit controller parameters.
Warning
When editing data record parameters, note that some of the parameters must be
identical in the data records:
• parameters changing the structure (different controller types such as PV or PID
controllers, for example)
• important activating parameters (following monitoring on/off, DSC on/off, for
example)
The consistency check reports any illegal technology parameter settings when you
configure data records in S7T Config.
Requirements
• Axis is configured.
