Siemens telegram 352, PZD 6/6
The standard control (control word, frequency setpoint etc.)
of SINAMICS G120 is implemented using the Siemens telegram.
In SINAMICS G120, instead of telegram 352 (fixed assignment
of the con-trol/feedback signal words), telegram 999 is used
(free assignment of the control/feedback signal words).
In this case, in SINAMICS G120, to start, telegram type 350
should be selected in parameter p922. This pre-assigns the
BICO connections. Telegram type 999 (free interconnection
via BICO) should then be selected and the following interconnections
made:
■ p2051[4] = r2131 (error number)
■ p2051[5] = r2110 (alarm number)
In order that SINAMICS G120 can use the safety functions in
the safety program, symbolic addresses must be assigned for
the inputs and outputs of the PROFIsafe module. The input
window for the symbolic addresses is opened by selecting the
PROFIsafe module, pressing the righthand mouse key and selecting
Edit symbols...
