- Packaging Machinery: High-speed form-fill-seal machines and cartoning lines requiring clean sinusoidal mains current and low harmonic distortion (THD <5%).
- Printing & Paper: Web-tension control systems on offset and gravure presses where four-quadrant operation is mandatory.
- Machine Tool & CNC: Multi-axis machining centers and grinding machines sharing a common DC bus with Motor Modules.
- Crane & Hoist: Overhead cranes and port gantries where lowering loads generate significant regenerative energy.
- Test Bench & Dynamometer: Engine and drivetrain test rigs requiring bidirectional power flow and ultra-stable DC bus voltage.
- Renewable Energy & Utilities: Grid-tie inverter test systems and power quality improvement installations.

Why Engineers Specify This Model
- True Four-Quadrant Operation: Feeds regenerative braking energy back to the mains grid rather than dissipating it as heat in braking resistors — reducing energy consumption and eliminating resistor maintenance.
- Sinusoidal Mains Current: Active front-end topology ensures THD <5%, protecting sensitive equipment on the same supply bus and meeting IEEE 519 / IEC 61000-3-12 harmonic limits.
- Stable DC Bus: Active voltage regulation maintains a stiff, stable DC bus for all connected Motor Modules, enabling precise coordinated motion across multiple axes.
- DRIVE-CLiQ Ecosystem: Plug-and-play integration with Siemens CU320-2 Control Units, SIMOTION D, and S7-1500T via PROFIBUS DP or PROFINET IRT.
- Compact Booksize Format: Optimized for high-density cabinet layouts; mounts directly alongside Motor Modules on a shared DC bus bar.
- Integrated Safety: Supports STO (Safe Torque Off) and SS1 (Safe Stop 1) safety functions per IEC 62061 / ISO 13849-1 PLe.

Application-Specific FAQ
Q: Does the 6SL3130-7TE21-6AA4 require an Active Interface Module (AIM)?
A: Yes. Siemens mandates the use of a matched Active Interface Module (e.g., 6SL3100-0BE21-6AB0) with every Active Line Module. The AIM contains the line reactor and EMC filter required for proper ALM operation and CE compliance.
Q: Can this ALM share a DC bus with Basic Line Modules or Smart Line Modules?
A: No. Active Line Modules operate at a higher DC bus voltage (~680 V) than Smart Line Modules (~600 V). All modules on a shared DC bus must be of the same infeed type.
Q: What is the maximum cable length between the ALM and the AIM?
A: Siemens specifies a maximum of 1.5 m between the ALM and AIM using the supplied busbars. Longer connections require engineering review.
Q: Is this module compatible with SIMOTION D?
A: Yes. The 6SL3130-7TE21-6AA4 integrates seamlessly with SIMOTION D4x5-2 via DRIVE-CLiQ and is fully supported in SCOUT TIA engineering software.
Q: What firmware version is required?
A: Firmware ≥ V4.7 SP9 is recommended for full feature support including Safety Integrated and PROFINET IRT. Check the Siemens Industry Online Support portal for the latest firmware.
Q: Can Konmask provide commissioning support?
A: Yes. Our technical team offers remote commissioning guidance, parameter backup files, and STARTER/TIA Portal project templates for standard applications. Contact [email protected].
