The following vendor-specific telegrams can be set via p0922:
– 102 Speed control with torque reduction, 1 position encoders
– 103 Speed control with torque reduction, 2 position encoders
– 105 DSC with torque reduction, 1 position encoders
– 106 DSC with torque reduction, 2 position encoders
– 370 Telegram for the infeed
3. Free telegrams (p0922 = 999)
The send and receive telegrams can be configured freely by using BICO
technology to interconnect the send and receive words.
– Interconnect the receive telegram (see function diagram 2460, 2481)
The following BICO outputs are available for interconnecting PZD receive
words 1 ... 16:
PZD receive word 1 ... 4
As connector output in DWORD and WORD format and as binector output.
PZD receive word 4 ... 16
As connector output in DWORD and WORD format and as binector output
via two connector/binector converters.
– Interconnect the send telegram (see function diagram 2470, 2483)
The following BICO inputs are available for interconnecting PZD send words
1 ... 16:
As connector input in DWORD and WORD format.
As binector input via two binector/connector converters.
Note
When you reset p0922 = 999 (factory setting) to p0922 999, the telegrams are
interconnected automatically.
When you reset p0922 999 to p0922 = 999, the previous telegram
interconnection is retained.
This is an easy method of interconnecting free telegrams as required on the basis
of existing telegrams.
