The SINAMICS G115D 6SL3520-0XH60-7AA0 is a terminal I/O Control 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 I/O Control variant uses hardwired digital I/O terminals for control — no fieldbus required — making it ideal for standalone conveyor sections or applications where network integration is unnecessary.

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.

How does the I/O Control variant differ from other G115D communication options?

The G115D platform offers three electronic module variants: terminal I/O Control (this model), PROFINET/EtherNet/IP, and AS-Interface. The I/O Control variant provides 4 PNP digital inputs (DI 0–DI 3) plus 2 bidirectional DI/DO points — all SIMATIC-compatible at 24 V DC. DI 0 and DI 1 can serve as HTL encoder inputs (track A/B), while DI 2 and DI 3 are configurable as fail-safe inputs for the integrated STO safety function. Control macros include 2-wire, 3-wire, motorized potentiometer, and fixed setpoints with Macro 65 preconfigured for conveyor operation with potentiometer setpoint.

What safety and protection features are included?

The drive integrates Safe Torque Off (STO) via a fail-safe digital input (F-DI), 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 enable rapid setup without specialized drive expertise — Macro 65 for I/O Control with potentiometer setpoint is preconfigured. 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.
