Control word and Status word
The Control Word (CW) is a 16-bit or 32-bit packed boolean word. It is the
principal means of controlling the drive from a fieldbus system. The CW is sent
by the fieldbus controller to the drive. With drive parameters, the user selects
the EFB CW as the source of drive control commands (such as start/stop,
emergency stop, selection between external control locations 1/2, or fault
reset). The drive switches between its states according to the bit-coded
instructions of the CW. The fieldbus CW is either written to the drive as it is or
the data is converted. See section
The fieldbus Status Word (SW) is a 16-bit or 32-bit packed boolean word. It
contains status information from the drive to the fieldbus controller. The drive
SW is either written to the fieldbus SW as it is or the data is converted. See
section

References
EFB references 1 and 2 are 16-bit or 32-bit signed integers. The contents of each
reference word can be used as the source of virtually any signal, such as the
speed, frequency, torque or process reference. In embedded fieldbus
communication, references 1 and 2 are displayed by
