The inverter saves the receive data in the "Word" format (r2050), in the "Double word" format
(r2060) and bit by bit (r2090 ...r2093). If you set a specific telegram, or you change the
telegram, then the inverter automatically interconnects parameters r2050, r2060 and r2090 ...
r2093 with the appropriate signals.
If you wish to adapt a predefined telegram, then you must interconnect the send and receive
data with the appropriate signals. To facilitate manual interconnection of send and receive
data, you must first adapt parameters p0922 and p2079.
For additional details relating to freely interconnecting process data, refer to the List Manual,
function diagrams 2420 and 2472.

Explanation
The motor brakes with the ramp-down time
p1121 of the ramp-function generator. The in‐
verter switches off the motor at standstill.
The inverter goes into the "ready" state. If, in
addition bit 3 = 1, then the inverter switches on
the motor.
Switch off the motor immediately, the motor
then coasts down to a standstill.
The motor can be switched on (ON command).
