Siemens 6SL3121-2TE13-0AA3 SINAMICS S120 Double Motor Module
A two-axis SINAMICS S120 power stage in the 3 A class, identified by the discontinued AA3 hardware suffix.
Overview
6SL3121-2TE13-0AA3 is a SINAMICS S120 Double Motor Module for two controlled motor axes in a common DC-link system. It combines booksize construction, an external cabinet cooling path and DRIVE-CLiQ integration. The full AA3 suffix is essential because Siemens assigns a later AA4 reference as its substitute.

Features
- Supplies two controlled motor connections from the modular S120 DC-link architecture.
- Uses optimized pulse patterns associated with this documented hardware generation.
- Carries control, topology and diagnostic information through DRIVE-CLiQ.
- Routes the principal power-stage heat through an external air-cooling arrangement.
- Supports system-level safety functions when they are engineered and validated in the complete drive project.
Applications
- Exact-spare maintenance for installed low-current dual-axis S120 machine sections.
- Two-axis servo groups that retain the original external-cooling cabinet interface.
- Lifecycle planning that compares the installed AA3 reference with its named AA4 substitute.
- Controlled shutdown work where the archived drive topology can be restored.
- Machine rebuilding projects that must preserve the documented electrical and cooling architecture.
Lifecycle
- Siemens classifies this order number in PM410 product cancellation.
- The official product record names 6SL3121-2TE13-0AA4 as the substitute.
- A substitute relationship does not remove the need to compare hardware, firmware and project dependencies.
- Retain motor, encoder, topology and safety data before removing the existing unit.
- Complete electrical, cooling and safety checks before returning both axes to operation.
FAQ
What does the TE13 current class mean for this module?
It identifies the low-current double-motor variant and must be matched with the complete suffix.
Why is the AA3 ending important during procurement?
It identifies the cancelled hardware generation and separates it from the later AA4 substitute.
Which project data should be archived first?
Save both axis parameters, motor and encoder data, topology and validated safety settings.
What cabinet feature must remain compatible?
The external air-cooling interface and service clearances must suit the selected replacement.
Does one module control one or two motors?
This is a Double Motor Module intended to provide two controlled motor outputs.
What proves a successful service replacement?
Both axes should pass wiring, direction, diagnostic, cooling and safety-function checks.
