Siemens SINAMICS S120: Sensor Module, Terminal Module, DRIVE-CLiQ and memory card
Around the Control Unit, Line Module and Motor Module, a SINAMICS S120 system uses many peripheral components: encoder modules, input and output modules, DRIVE-CLiQ hubs and cables, communication boards and memory cards with the firmware. They are small, but if one of them fails the drive stops.
The E-Repair catalogue covers about 155 part numbers for these components.

⚠️ Typical faults
- Sensor Modules damaged by overvoltages or faulty encoder cables
- Terminal Modules with burnt-out input or output channels
- damaged DRIVE-CLiQ cables, with topology or communication errors
- corrupted or unreadable memory cards, with loss of firmware and parameters
The memory card holds the drive licences and parameters: keeping a copy of it is the simplest protection against long downtime.

❓ Frequently asked questions
✔️ Can a Sensor Module or Terminal Module be repaired?
Yes, in many cases. E-Repair carries out a diagnosis and assesses a component-level repair.
✔️ Does anything need reconfiguring after replacing a DRIVE-CLiQ module?
Generally the drive recognises the component; if the topology has changed it must be confirmed in the configuration. It is advisable to have a project backup.
✔️ Can the memory card be copied?
Yes, a backup copy of the memory card is strongly recommended. For licences, the manufacturer's rules must be respected.
