Siemens SIMOVERT MASTERDRIVES 6SE70 Series Technical Notes

The Siemens SIMOVERT MASTERDRIVES 6SE70 series represents one of the most widely deployed AC drive platforms in global heavy industry. Installed across petrochemical complexes, nuclear power auxiliary systems, offshore platforms, steel rolling mills, and large-scale water treatment facilities, the 6SE70 platform covers power ranges from 0.55 kW to several megawatts in both Vector Control (VC) and Motion Control (MC) variants. Its modular architecture — separating power electronics, control intelligence, and communication into discrete, field-replaceable units — made it the reference standard for process-critical drive applications throughout the 1990s and 2000s. The platform remains active in lifecycle support mode, with a substantial installed base requiring ongoing spare parts procurement and repair services.

The Evolution of SIMOVERT MASTERDRIVES 6SE70 Architecture

The 6SE70 series was introduced in the early 1990s as the successor to the SIMOVERT P and SIMOVERT A families, consolidating Siemens' AC drive portfolio under a unified hardware platform. The initial release established the core backplane bus architecture (the CUVC and CUMC control unit concept), enabling a single power section to be reconfigured for different application profiles by swapping the control board.

The first-generation control units (CUVC A) used proprietary serial communication. By the mid-1990s, Siemens introduced PROFIBUS-DP integration via the CBP (Communication Board PROFIBUS) adapter, enabling the 6SE70 to participate in distributed automation architectures alongside SIMATIC S5 and early S7 PLCs. The introduction of the T400 technology board extended the platform into coordinated multi-axis applications such as winders, draw rolls, and extruder lines.

Quality Control for the SIMOVERT MASTERDRIVES 6SE70 Range

The 6SE70 platform's modular backplane architecture introduces specific failure modes that require targeted test procedures beyond standard power electronics inspection. Backplane bus integrity is verified using a dedicated CUVC test fixture that simulates the full slot communication cycle, confirming that the local bus adapter (LBA) and all populated slot connectors meet the original Siemens impedance specification. PROFIBUS-DP communication boards (CBP2) are tested at 1.5 Mbit/s and 12 Mbit/s with a live PROFIBUS master to confirm GSD file compatibility and cyclic data exchange. Encoder evaluation boards (SBP, SBR1) are tested with reference encoder signals at 1024 PPR and 4096 PPR to verify count accuracy and fault detection response. All control units are powered through a controlled 24 VDC supply and subjected to a full parameter upload/download cycle using STARTER or DriveMonitor software to confirm EEPROM integrity and firmware version consistency. Capacitor ESR measurement is performed on all boards with electrolytic capacitors older than 10 years.
