About Siemens SIMOVERT MASTERDRIVES Motion Control Inverter (6SE7021-3TP50-Z), 3-Phase output, 13.2 A nominal current, Compact Plus Unit, IP20 panel-mount heavy-duty motion controller
Execute high-dynamic multi-axis servo positioning loops with the high-reliability Siemens SIMOVERT MASTERDRIVES Motion Control Inverter (6SE7021-3TP50-Z). Specifically engineered by Siemens as a high-performance Compact Plus Unit for synchronized automation systems, this dedicated DC/AC inverter optimizes AC servo motor performance through rapid speed, torque, and position regulation. Rather than connecting directly to an AC grid line, this drive hooks into a common DC link distribution system, accepting an incoming 510V to 650V DC bus voltage and delivering a steady 13.2 Amp nominal output current to achieve a robust 5.5 kW (7.5 HP) power rating.
The core electrical and physical framework is built into a space-efficient, book-size IP20 enclosure measuring
13.5 x 36.0 x 26.0 cm, designed for tight, side-by-side electrical cabinet installations. Optimized for heavy continuous manufacturing, its advanced software architecture excels in high-response configurations such as packaging lines, robotic cells, and material handling systems. The
"-Z" suffix denotes a customized factory hardware layout preconfigured with critical option modules, typically adding specialized communication, functional feedback loops, or protective safety bits right out of the box. [
Important Lifecycle & Maintenance Status: The entire legacy SIMOVERT MASTERDRIVES platform is officially discontinued and no longer in active production. Siemens has fully replaced this legacy line with the current SINAMICS S120 multi-axis drive platform for brand-new systems. However, factory-boxed surplus and certified refurbished units remain widely traded as direct drop-in spare parts to maintain existing manufacturing plant lifecycles.
