Siemens SIMOVERT MASTERDRIVES is a legacy AC drive family designed for variable-speed motor control across a wide range of power ratings in industrial applications. SIMOVERT MASTERDRIVES hardware covers vector control and motion control drive converters, power supply modules, control modules, and operating units for variable-speed drive systems in manufacturing, process, and infrastructure applications. The collection at PLC Direct focuses on SIMOVERT MASTERDRIVES components and spare parts, the majority of which carry PM410 (Product cancellation) or PM490 (Start of final year of support) lifecycle status.
PLC Direct supplies Siemens SIMOVERT hardware to maintenance teams, keeping existing MASTERDRIVES installations running. Our collection of 320 products covers SIMOVERT MASTERDRIVES control modules, power supply modules, operating units with integrated memory, and technological boards for installed MASTERDRIVES systems.
Where Siemens SIMOVERT Is Used
A failed SIMOVERT MASTERDRIVES control module or power supply module in an active drive application takes that drive out of service until a replacement component is located. Because SIMOVERT MASTERDRIVES is a discontinued product line, OEM distribution channels no longer carry most spare parts, and finding specific module variants requires access to independent stock. For facilities running MASTERDRIVES hardware that has been in service for years, maintaining spare parts availability is a long-term maintenance requirement.
Facilities that depend on Siemens SIMOVERT hardware include:
-
Industrial manufacturing plants running SIMOVERT MASTERDRIVES variable-speed drives on conveyor, fan, pump, and compressor applications.
-
Process facilities with MASTERDRIVES installations where control or power module failures require immediate replacement to restore production
-
Water and wastewater utilities operating SIMOVERT-controlled pump drives that cannot be replaced with newer hardware without major panel modifications
-
Mining operations with SIMOVERT MASTERDRIVES drives on hoist, crusher, and conveyor systems, where legacy hardware remains in service.
-
Steel, paper, and textile mills running MASTERDRIVES vector control or motion control drives for process speed and torque control.
-
Facility maintenance teams managing spare parts inventory for SIMOVERT installations with no near-term hardware upgrade plans
When a SIMOVERT MASTERDRIVES component needs to be replaced to restore an installed drive, having access to surplus sealed or refurbished stock from an independent supplier is often the only path to a rapid repair.

What to Know Before You Buy Siemens SIMOVERT Parts
Ordering the correct SIMOVERT MASTERDRIVES component requires identifying the specific module type, the installed drive's design variant, and, where applicable, the firmware version. SIMOVERT MASTERDRIVES is a modular system, and modules are not universally interchangeable across all drive variants and sizes.
Hardware condition options: PLC Direct supplies SIMOVERT hardware as surplus sealed, refurbished, and used. Surplus sealed units are factory-sealed stock; refurbished units have been tested and restored to operational condition.
Lifecycle status: The majority of SIMOVERT MASTERDRIVES products in this collection carry PM410 (Product cancellation) or PM490 (Start of final year of support) lifecycle designations. These are discontinued parts, no longer manufactured by Siemens. PLC Direct supplies them as replacement stock for existing installations.
Technological Board T100 software: The T100 Technological Board (6SE70900XX870BB0) is supplied without a software module. The required software module and LBA adapter must be ordered separately to enable the board's technology functions. Confirm the software module part number required for the specific application before ordering.
Power supply module design variant: The PSU1 power supply module (6SE7031-7HG84-1JA1) is compatible with SIMOVERT MASTERDRIVES devices in Design variants E through H. SIMOVERT MASTERDRIVES design variants are identified by the cabinet housing and size designation. Verify the drive's design variant before ordering a PSU1.
CUSA module firmware version: The CUSA AFE control module in this collection carries firmware version V2.XX. Confirm that the firmware version is compatible with the installed drive configuration and software version before ordering.
Warranty: All Siemens SIMOVERT hardware purchased from PLC Direct includes a standard 1-year warranty covering defects and functionality, applicable to surplus sealed, refurbished, and used products.
