Telegram selection
You select the telegram using p0922.
You can select any of the listed telegrams if you are working with the SINAMICS profile.
If you use the AC/DC profile of the ODVA, select the standard telegram, p0922 = 1. You
cannot work with the EDS file if you wish to use the assemblies described in Section
Supported objects (Page 140). In this case, you must integrate the inverter into your control
system.
Setting the bus monitoring time
You set the bus monitoring using parameter p8840 in the inverter.
If you set this parameter to 0, the inverter continues to operate even if the bus develops a
fault condition. If you set a time ≠ 0, then the inverter switches off with F08501 "Setpoint
timeout" if the control system does not issue any signals within this time.

control system with objects 90 hex or 91 hex.
Setting the off response for the motor
You set the standard off response for the inverter using parameter p8981:
● p8981 = 0: OFF1 (factory setting), also corresponds to the setting in the SINAMICS
● p8981 = 1: OFF2
You can find details on OFF1 and OFF2 in section Switching the motor on and off
(Page 227)
