This is the replacement control board assembly for those drive frames — not a standalone drive, but the logic and firing board that sits inside the drive chassis. The VW3A58821 is designed for Altivar ATV58 drives in the size 1 mechanical format, covering the ATV58U09M2, ATV58U12M2, and ATV58U18M2 models. These are 200-240 V single-phase input drives rated for 0.75 kW, 1.1 kW, and 1.5 kW motor output respectively. The control card kit includes the main control PCB with the processor, I/O terminals, and the keypad interface connector — it is the board that the drive's firmware and parameter set live on. ## What to verify before ordering Because this is a control board replacement inside a drive that has been out of production for years, the firmware revision on the replacement board may differ from the original. If the drive is in a critical line and the parameter file is not backed up, plan for a full re-commissioning cycle — the new board will arrive with factory defaults, not the site-specific settings. The ATV58 series uses Schneider's proprietary programming software (PowerSuite or the older ATV58 keypad display) for parameter transfer.","metaTitle":"Schneider VW3A58821 Control Card Kit, ATV58 Size 1, Obsolete","metaDescription":"Obsolete Schneider VW3A58821 control card kit for Altivar ATV58 variable speed drives size 1.
