PROFIdrive control and status words

The control word, STW1, is the principal means for controlling the drive. It is sent by the controller (PLC)
to the device (inverter). The bitmapping for the control word is described in Table 36. The status word,
ZSW1, returns status information from the inverter to the controller. The bitmapping for the status word
is described in Table 37.
