Forced local mode
Definition
Forced local mode supports switching to the terminals or display terminal.
This function complements channel switching and makes it possible to make use of an existing function from the Altivar 58 range.
Forced local mode is only available in CiA402 profile, not in I/O profile.
All other communication takes priority over forced local mode.
Forced local mode can be configured via the display terminal:

In "forced local" state:
•Any attempts to write the parameter via one of these channels is rejected (applies to command, reference and adjustment parameters).
•However, the parameters can be read.
•The drive does not register a communication fault.
On exiting "forced local" mode:
•The drive copies the run commands, the direction and the forced local reference to the active channel (maintained).
•Monitoring of the active command and reference channels resumes following a time delay
•Drive control only takes effect once the drive has received the reference and the command.
