The telegrams use - with the exception of telegram 999 (free interconnection) - the word-by-
word transfer of send and receive data (r2050/p2051).
If you require an individual telegram for your application (e.g. for transferring double words),
you can adjust one of the predefined telegrams via parameters p0922 and p2079. For
details, please 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).
