Features
- Two-axis power-stage construction within the modular SIMODRIVE 611 drive system.
- Internal heat dissipation for an engineered cabinet cooling path.
- Two motor output groups plus protective-conductor connections.
- Shared P600/M600 DC-link interface with the drive group.
- Exact CA3 suffix supports controlled spare identification.
Applications
- Legacy machine tools using a CA3 two-axis SIMODRIVE 611 power module.
- Planned maintenance where both motor circuits and both axis control configurations are documented.
- Replacement work requiring verification of infeed capacity, cabinet cooling and terminal placement.
Lifecycle
- Keep the CA3 suffix visible in purchasing, receiving and installation records.
- Record both axis-control cards, motors, feedback systems and parameter sets before removal.
- Check the A1/A2 terminal arrangement against the machine drawings.
- Commission each axis separately after DC-link and protective-conductor checks.
FAQ
What is the system role of 6SN1123-1AB00-0CA3?
6SN1123-1AB00-0CA3 supplies two motor outputs in a compatible SIMODRIVE 611 drive group.
Which revision is identified by 6SN1123-1AB00-0CA3?
The complete article identifies the CA3 revision.
How is 6SN1123-1AB00-0CA3 cooled?
6SN1123-1AB00-0CA3 uses internal heat dissipation and therefore depends on the engineered cabinet cooling path.
What terminal warning applies to 6SN1123-1AB00-0CA3?
Siemens notes that the A1/A2 arrangement on the CA2/CA3 two-axis modules differs from other two-axis versions.
What should be backed up before a 6SN1123-1AB00-0CA3 exchange?
Back up both axis parameter sets and record motor, feedback, control-card and wiring data.
Can 6SN1123-1AB00-0CA3 replace a one-axis 50 A module?
No. 6SN1123-1AB00-0CA3 is a two-axis construction and must be matched to the machine architecture.
