This manual introduces the MICROMASTER series of frequency converters, covering four models (410, 420, 430, 440) with power ranges from 0.12 kW up to 250 kW. It describes typical applications such as pumps, fans, conveyors, and industrial machinery, and lists the available supply voltages for single‑phase and three‑phase operation.
The document contains detailed wiring diagrams, technical specifications, selection and ordering data, optional modules (e.g., PROFIBUS, DeviceNet, encoder modules), and service procedures. It also includes dimensions, cooling information, EMC compliance, and warranty/repair instructions for field service. This manual is written in Chinese.
