● Parameter p2070 is used to define at which location (after how many words) the SCC
starts in receive words r2050/r2060.
● Parameter p2071 is used to define at which location (after how many words) the SIC
starts in send words p2051/p2061.
● If, using p0922 = 999 and p2079 = x, a fixed telegram is to be parameterized with PZD
extension, then you can appropriately adapt p2070 and p2071.
● For p0922 = p2079 = x, p2070 and p2071 are locked to prevent changes being made.
● When writing to parameter p0922 or p2079, parameters p2070 and p2071 are
appropriately preassigned (with the length of the standard telegram). All BICO
interconnections in r2050[...]/r2060[...] and p2051[...]/p2061[...] are deleted and
reassigned to telegram x. In so doing, p60122 is also set = 999.
● When changing from a fixed telegram (p0922 = p2079 = x) to a free telegram (p0922 =
999), p2070 and p2071 remain unchanged, however they are released so that they can
be changed. The value of p60122 is kept.
● If p10235 and p10250 are manually changed, fault F01786 is output without any drive
response. This fault can be acknowledged by the standard message acknowledgment.
Note
Effects in r2050[...]/r2060[...] and p2051[...]/p2061[...] when changes are made to p2070,
p2071 and p60122
• If you change p2070 and p2071, all BICO interconnections in r2050[...]/r2060[...] and
p2051[...]/p2061[...] will be deleted (starting with the end of the currently set standard
telegram). In so doing, p60122 is also set = 999.
• If you change p60122 to a value ≠ 999, then (starting with the indices set in p2070 or
p2071) all BICO interconnections are deleted in r2050[...]/r2060[...] and
p2051[...]/p2061[...] and the new telegram set for SIC/SCC.
