Description of choice:
Index 0 to 11:
These are the twelve display values which are also avail-
able in the Extended Display. Only the value of the display
is sent via the serial interface, not the unit.
Index “0”. REFERENCE %, represents only external speed
reference signals: analog inputs on terminals 53 and 60,
the pulse from input on terminal 17, and the serial bus ref-
erence. It does not include the jog speed set by parameter
203 or the digital references set by parameters 205 through
208.
Index 12:
A decimal value, which is to be converted to an 8-bit binary
code. This represents the status of the binary inputs.

Index 13 and 14:
A decimal value between 0 and 1023, where 0 corresponds
to 0% and 1023 corresponds to 100% of the selected input
signal, for example 0 to 10 V DC.
Index 15:
A decimal value which is to be converted to a 16-bit binary
number. Each bit represents a warning in accordance with
the table below. When a warning is present, the corre-
sponding bit has the value “1”.
The warnings are described at the end of the programming
section..

Index 16:
A decimal value which is to be converted to a 16-bit binary
number. Each bit represents a control command. When a
control command has been activated, the corresponding bit
has the value “1”.
Index 17:
A decimal value which is to be converted to a 16-bit binary
number. Each bit represents a status message. When a
status message is present, the corresponding bit has the
value “1”.
Index 18:
A decimal value which is to be converted to a 16-bit binary
number. Each bit represents an alarm. When an alarm is
present, the corresponding bit has the value “1”.
