The Siemens 6SE7090-0XX84-2FA0 SIMOVERT MASTERDRIVES PMU is the compact operator and parameter-assignment unit designed for quick local setup, monitoring, and fine-tuning of SIMOVERT Masterdrives in Design A and B systems. Ideal for field technicians and plant engineers, this PMU speeds commissioning and reduces downtime by providing a straightforward, local interface for parameter entry, status readouts, and fault diagnostics.
This PMU allows direct parameter input, visualization of drive status, and straightforward operator control without requiring a laptop or specialized software. With its four-digit display and intuitive controls (as described in Siemens operating documentation), technicians can change or monitor key drive settings, review alarms, and perform initial start-up parameterization on-site — saving time during commissioning and troubleshooting.
Manufactured to integrate with SIMOVERT MASTERDRIVES, the 6SE7090 PMU is a spare/field-replaceable part for a range of legacy Siemens drives. It's compact, lightweight, and engineered to match the rugged demands of industrial environments where precise motor control and reliable operator feedback are essential. If you maintain older SIMOVERT installations, the PMU is a practical replacement to quickly restore local control functionality.
Important: Siemens lists this PMU as a spare part and indicates the product has reached end-of-life status; it was discontinued by the manufacturer and moved to final support. Many trusted industrial distributors and refurbishers still stock new, used, and refurbished units with seller warranties and same-day shipping options — a convenient path if OEM stock is depleted. Always verify the warranty and return policy with the seller before purchasing.
If you're searching for "SIMOVERT Masterdrives PMU," "6SE7090 operator unit," or "parameter assignment unit for Design A B," this part delivers native integration, proven Siemens quality, and a simple local interface to keep your drives running smoothly. Whether rebuilding panels, repairing inverters, or stocking spares for preventive maintenance, the 6SE7090-0XX84-2FA0 remains a high-value component for legacy Siemens drive systems.
Is the 6SE7090-0XX84-2FA0 the correct PMU for SIMOVERT Masterdrives Design A and B?
Yes — this part was explicitly produced as the operating/parameter-assignment unit (PMU) for devices of Design A and B in the SIMOVERT Masterdrives family.
How do I input parameters with the PMU?
Parameters are entered directly via the PMU's display and controls; Siemens documentation outlines the parameter lists and step-by-step input process for initial start-up and adjustments.
Is this PMU still manufactured by Siemens?
No — Siemens lists the product as discontinued/legacy (end-of-life). You can still find new-old-stock, refurbished, and used units through industrial distributors.
Can I replace a faulty PMU myself?
Yes — the PMU is a field-replaceable operator panel; follow safety and lockout procedures and consult the unit's operating instructions for correct removal and installation steps.
Will a replacement PMU require special software?
No — the PMU enables local parameterization without a PC; however, for advanced parameter lists and batch programming, you may still use SIMOVIS or PC-based tools if available.
Is the PMU compatible with software tools like SIMOVIS?
Yes — the PMU works alongside PC-based parameter tools (SIMOVIS/Drive Monitor) for deeper diagnostics and parameter management.
What should I check before ordering a replacement PMU?
Verify the Design A/B compatibility, part number match (6SE7090-0XX84-2FA0), condition (new vs refurbished), seller warranty, and return policy. Confirm shipping lead time for urgent repairs.
Can this PMU fix drive faults?
The PMU helps diagnose and apparent faults and provides operator-level control; it is an interface — not a replacement for underlying power electronics — but restoring a working PMU often speeds troubleshooting and resets.
Looking for this PMU for multiple drives — should I stock spares?
Yes — for facilities running legacy SIMOVERT systems, keeping a PMU spare reduces downtime and supports faster field repairs since the part is discontinued, and lead times for replacements can vary.
