4.2.5 Broadcast telegrams
To control several frequency inverters simultaneously (e.g. same enable and same setpoint), it is
possible to address frequency inverter groups or all frequency inverters using broadcast telegrams.
This means that, in addition to the identifiers described above, additional broadcast identifiers for each
frequency inverter are also valid. A range of 32 addresses is assigned to one broadcast identifier. All
connected frequency inverters can be controlled using the broadcast identifier 1032.
CAN address (P515) Broadcast identifier
00 - 31 1024 (400h)
32 - 63 1025 (401h)
64 - 95 1026 (402h)
96 - 127 1027 (403h)
128 - 159 1028 (404h)
160 - 191 1029 (405h)
192 - 223 1030 (406h)
224 - 255 1031 (407h)
0 - 255 1032 (408h)
