♦ The "tens digit" of the binector enables a distinction to be made
between a 16-bit item of process data (e.g. 3002) and a 32-bit item
of process data (e.g. 3032).
♦ If an item of process data is transferred as a 16-bit quantity, you
must assign the connector which belongs to the desired PZDi and
which is for a 16-bit item of process data (e.g. if PZD2 is assigned a
16-bit item of process data, the relevant connector is 3002) to the
selection switch (see section "Control Word and Status Word" in the
instruction manual of the converter).
♦ If an item of process data is transferred as a 32-bit quantity, you
must assign the connector which belongs to the desired PZDi and
which is for a 32-bit item of process data (e.g. if PZD2+PZD3 are
assigned a 32-bit item of process data, the relevant connector is
3032) to the selection switch (see section "Control Word and Status
Word" in the instruction manual of the converter).
♦ The first word (relevant connector: 3001) of the received process
data is always allocated to control word 1 (STW1). The meaning of
the control-word bits is given in the operating instructions for the
converter in the section, "Start-up aids".
♦ The second word is always allocated to the main setpoint (HSW).
If the main setpoint is transferred as a 32-bit item of process data, it
also occupies word 3. In this case, the most significant component is
transferred in word 2 and the least significant component in word 3.
♦ If a control word 2 (STW2) is transferred, the fourth word (relevant
connector = 3004) is always allocated to STW2. The meaning of the
control-word bits is given in the instruction manual for the converter
in the section, "Start-up aids".
♦ The connector is always a four-digit number. The connectors
assigned to the process data (PZD1 to PZD16) are given in the
function plan.
♦ The connector is entered at the PMU as a 4-digit number (e.g.
3001). During parameterization via the CAN bus, the connector is
entered via the bus in the same way as via the PMU (e.g. connector
3001 is transferred as 3001(hex)).
Process-data connection (softwiring) of the setpoint channel can also
be carried out via the CAN bus as long as P053 has previously been
set to an odd number.
