Why Engineers Specify This Model
- DRIVE-CLiQ Integration – Plug-and-play digital communication with SINAMICS S120 Control Units (CU320-2, CU310-2) eliminates manual encoder parameterization
- High Overload Rating – 200% peak current for 5 seconds handles aggressive acceleration profiles without derating
- Booksize Form Factor – Compact rail-mount design minimizes cabinet footprint; modules share a common DC bus for energy recovery
- Integrated Safety Functions – Supports STO (Safe Torque Off) and SS1 (Safe Stop 1) per IEC 62061 / EN ISO 13849-1
- Scalable Architecture – Mix and match with other S120 Motor Modules on a single Line Module for multi-axis systems
- Proven Reliability – MTBF data and global installed base in excess of 1 million drives worldwide
Complete System Bill of Materials
The 6SL3120-1TE21-0AD0 operates as part of the SINAMICS S120 booksize system. A typical single-axis servo system requires:
- Active Line Module or Smart Line Module (e.g., 6SL3130-7TE21-6AA3) – DC bus supply
- 6SL3120-1TE21-0AD0 – Single Motor Module (this item)
- Control Unit CU320-2 DP or CU320-2 PN (e.g., 6SL3040-1MA01-0AA0)
- SIMOTICS S servo motor with DRIVE-CLiQ encoder (e.g., 1FK7 or 1FT7 series)
- DRIVE-CLiQ cables (6FX2002-1DC00 series)
- Braking resistor (if regenerative energy cannot be fed back to grid)
- 24 V DC SITOP power supply for control electronics
Compliance & Industry Standards
- CE Marking – Compliant with EU Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU
- UL / cUL Listed – Recognized per UL 508C (Power Conversion Equipment)
- IEC 61800-5-1 – Adjustable speed electrical power drive systems safety requirements
- IEC 61800-3 – EMC requirements for drive systems
- EN ISO 13849-1 / IEC 62061 – Functional safety (STO: PLe / SIL 3 capable)
- RoHS Compliant – Directive 2011/65/EU

Application-Specific FAQ
Q: Can the 6SL3120-1TE21-0AD0 be used with a SINUMERIK 840D sl CNC controller?
A: Yes. The SINAMICS S120 platform is the native drive system for SINUMERIK 840D sl. The module communicates via DRIVE-CLiQ and is fully parameterized through the NCK/PLC interface.
Q: What Line Module is required to power this Motor Module?
A: Any SINAMICS S120 booksize Line Module with sufficient DC bus power capacity. For a single 18 A Motor Module, a 16 kW Smart Line Module (6SL3130-6AE21-6AB0) or Active Line Module is typical.
Q: Is STO (Safe Torque Off) available without an additional safety option board?
A: Yes. STO is integrated as a standard safety function in the 6SL3120-1TE21-0AD0 via the EP terminals, achieving PLe / SIL 3 when wired per Siemens safety guidelines.
Q: Can this module drive a linear motor or torque motor?
A: Yes, provided the motor has a compatible DRIVE-CLiQ or TTL/HTL encoder interface and the current rating is within the 18 A continuous / 36 A peak envelope.
Q: What firmware version is pre-loaded?
A: Firmware version varies by production date. Konmask supplies units as-received; firmware upgrade via STARTER or TIA Portal Startdrive is straightforward and documented in Siemens Function Manual.
