Command Mode Selection and Priorities
The diagram below illustrates the control inputs and selection logic which determine the source of the drive's
start/stop and speed reference commands.
Command and Reference Switching
Parameters [Command mode sel] (CMOd) and [Frequency mode sel] (FMOd) are the first layers of logic used
by the drive to determine its command CMOd and speed reference FMOd source.
[Remote spd ref 2] (F207) is a secondary speed reference source that may override the source selected by
FMOd (see page
77).
The speed reference source identified by F207 takes control if either:
z A logic input assigned to function 38 (frequency reference source switching) is enabled, or
z Parameter [Auto/man speed ref] (F200) is set to 1 and the drive's output frequency is equal to or less than
1 Hz (see page 108).
If a serial communication link is established, it can take control of the ATV212 drive, overriding inputs identified
by CMOd, FMOd, and F207. Control is restored to CMOd, FMOd, and F207 only if:
z The serial communication link relinquishes control, or
z A logic input assigned to function 48 (forced local) is enabled.
The final layer of logic used by the drive to determine its command source is the LOC/REM key on the graphic
display option.
When the drive and embedded HMI is set to local mode (by pressing the LOC/REM key, lighting the local mode
LED), the drive responds only to commands from the embedded and graphic display option.
