Enable Logic - Siemens SINAMICS S120 Commissioning Manual

The encoder resolution is too low here to convert the chain links to a linear SI unit without
rounding-off errors having an effect on the modulo correction. A chain link must therefore be
taken as target variable.
Target variable to be controlled: 1 chain link
40 chain links travelled per load revolution. According to the encoder resolution, maximum
468,095 LU/40 chain links = 11,702 LU per chain link can be selected. We will therefore
select 1,000 LU per chain link (1 LU = 33.8667344 µm). 40 chain links per revolution results
in:
● p2506 = 40,000 LU per load revolution
● p2576 = 250,000 LU modulo range

Enable logic

☐
If, when commissioning, you interconnected telegrams, then these interconnections are
displayed in the "Enable logic" screen form. Further specification is not required.
If, when commissioning, you did not specify any telegram types, then you must interconnect
the required signal sources in the "Enable logic" screen form.
Interconnecting signal sources
1. Connect the signal source for the "Infeed operation" (p0864) command.
2. Connect the signal source for the "OFF1 (low active)" command (p0840).
This command corresponds to control word 1 bit 1 (STW1.1) in the PROFIdrive profile.
3. Connect the 1st signal source for the "OFF2 (low active) signal source 1" command
(p0844).
This command corresponds to control word 1 bit 1 (STW1.1) in the PROFIdrive profile.
4. Connect the 2nd signal source for the "OFF2 (low active) signal source 2" command
(p0845).
5. Connect the 1st signal source for the "OFF3 (low active) signal source 1" command
(p0848).
This command corresponds to control word 1 bit 2 (STW1.2) in the PROFIdrive profile.
6. Connect the 2nd signal source for the "OFF3 (low active) signal source 2" command
(p0849).
This command corresponds to control word 1 bit 2 (STW1.2) in the PROFIdrive profile.
7. Interconnect the signal source for the "Enable operation" command (p0852).
This command corresponds to control word 1 bit 3 (STW1.3) in the PROFIdrive profile.
