The SINAMICS G115D 6SL3520-0XH61-1AA0 is a wall-mounted distributed inverter drive engineered for horizontal conveyor applications. As part of the Siemens decentralized drive platform, it eliminates the need for a control cabinet — mounting directly on the machine to reduce footprint, simplify cabling, and lower cooling requirements. The drive comes fully preconfigured for integration with SIMATIC control systems via TIA Portal, supporting both simple V/f speed control and sophisticated encoderless vector control across a 0–550 Hz output range.

What motor configurations does this drive support?

The G115D pairs with SIMOGEAR 2KJ8 geared motors, available with IE3-class three-phase asynchronous motors or IE4-class synchronous reluctance motors. The wall-mounted converter connects via a Q80 motor connector and accommodates speed ranges from 1:5 up to 1:10, covering 300 to 3,000 min⁻¹ depending on the configured control range. An integrated 180 V DC brake output is provided as standard for motor holding brake control.

What safety and protection features are included?

The drive integrates Safe Torque Off (STO) via a fail-safe digital input (F-DI) or PROFIsafe, meeting functional safety requirements without external safety relays. The IP65/IP66 enclosure with UL Type 4X rating allows installation in washdown and harsh industrial environments, with an operating temperature range of −30 °C to +40 °C (extendable to +55 °C with derating). A built-in Category C2 EMC filter per EN 61800-3 simplifies compliance.

How does the G115D simplify commissioning and maintenance?

Predefined macros and preconfigured TIA Portal function blocks enable rapid setup without specialized drive expertise. An optional SD memory card allows parameter transfer between units for fleet-wide commissioning, while an available web server module supports wireless diagnostics and remote configuration. The modular platform shares common components across wall-mounted and motor-mounted G115D variants, streamlining spare parts management across the installation.
