Parameter conguration
The real-time control bits and real-time status bits can be congured in phases 2, 3
and 4.
The assignment parameters contain the number of the parameter to be congured for
the related real-time bit.
During conguration it is to be noted that the bit number must be assigned rst
(S-0-0413, S-0-0414, S-0-0415, S-0-0416) before a corresponding IDN is assigned as
the real-time bit (S-0-0301, S-0-0303, S-0-0305, S-0-0307).
6.4.2 Conguration of real-time bits, SERCOS III
y S-0-1050.x.20 "IDN – assignment real-time bit": IDN of the parameter
that is to be assigned to the related real-time bit.
y S-0-1050.x.21 "Bit – assignment real-time bit": Denition of which
bit number of the parameter assigned is to be represented.
6.5 Signal control word and signal status word
6.5.1 Signal control word (S-0-0145)
Signals can be transferred from the controller to the drive in real-time in the signal
control word S-0-0145. The signal control word can be congured for the cyclic
transfer in the master data telegram (MDT). The signal control word is congured in
phase 2 and is activated on the transition to phase 3. An erroneous conguration will
result in a device error and it will not be possible to switch to phase 3. The conguration
parameters for the signal control word are described in the following table.
S-0-0027 Conguration list for signal control word
This list contains all parameter numbers that are contained in the signal control word.
The sequence of the parameter numbers in the list denes the signicance of the bits
in the signal status word. The rst parameter in the list denes bit 0, the last parameter
number bit 15. The parameter S-0-0328 denes the bit number from the related
parameter that is to be given in the signal status word.

S-0-0027 Conguration list for signal control word
The bit numbers for the parameters from S-0-0027 copied to the signal control word
(S-0-0145) are programmed in this conguration list. The sequence of the bit numbers
in the list is that same as the sequence of the signals in the signal control word.
Table 6.8 Conguration parameters for the signal control word
The list of congurable parameters for the real-time status bits P3002 applies for the
conguration of the signal status word.
6.5.2 Signal status word (S-0-0144)
The drive status congured by the user can be represented in the signal status word
S-0-0144. The signal status word can be congured for the cyclic transfer in the drive
telegram (AT). The signal status word is congured in phase 2 and is activated on the
transition to phase 3. An erroneous conguration will result in a device error and it will
not be possible to switch to phase 3. The conguration parameters for the signal status
word are described in the following table.
S-0-0026 Conguration list for signal status word
This list contains all parameter numbers that are contained in the signal status word.
The sequence of the parameter numbers in the list denes the signicance of the bits
in the signal status word. The rst parameter in the list denes bit 0, the last parameter
number bit 15. The parameter S-0-0328 denes the bit number from the related
parameter that is to be given in the signal status word.
S-0-0328 Signal status word bit number assignment list
The bit numbers for the parameters from S-0-0026 copied to the signal status word
(S-0-0144) are programmed in this conguration list. The sequence of the bit numbers
in the list is that same as the sequence of the signals in the signal status word.

The list of congurable parameters for the real-time status bits P3002 applies for the
conguration of the signal status word.
