Buyers carrying a spare for a running line should treat this as a stock-out part: cross out the OEM-channel refresh and route through a specialist who can name the warehouse, the lot, and the inspection report per unit — for an audit trail that survives a tender challenge. ## Mechanical envelope on the shop floor Because the motor is part of a synchronous servo pair — drive electronics, encoder cable, and resolver or absolute-encoder feedback — the swap should be staged so the replacement unit's encoder option matches the drive's firmware expectation; a mismatched feedback type is the most common line-stop cause on this frame.","metaTitle":"Siemens 1FK70345AF211UA3 servo motor, 1.6 Nm, 0.63 kW","metaDescription":"Siemens 1FK70345AF211UA3 synchronous servo, 3AC, 1.6 Nm, 0.63 kW, 3000 rpm, lifecycle eol_hot.
