This module integrates a dedicated \u003cstrong\u003ePower Supply Unit D22A\u003c\/strong\u003e with an advanced control PCB assembly, comprising the \u003cstrong\u003eVAC Board II\u003c\/strong\u003e and \u003cstrong\u003eVAC Card 1\u003c\/strong\u003e, to deliver reliable power conversion and signal processing. Rated for a continuous power capacity of 22 kW, the VACII D22-A supports stable spindle operation under heavy machining loads. Its built-in \u003cstrong\u003eCooling Fan Motor Voltage 200V, 50\/60 Hz\u003c\/strong\u003e configuration ensures consistent thermal management in industrial environments. Equipped with industry-standard rack-mount dimensions, it seamlessly integrates into automated manufacturing cells.\u003c\/p\u003e\n\n\u003cp\u003eThe VACII D22-A features a robust electrical architecture with \u003cstrong\u003eMain Transformer Primary Voltage 200V\u003c\/strong\u003e and dual \u003cstrong\u003eMain Transformer Secondary Voltages 19V, 105V\u003c\/strong\u003e outputs for auxiliary circuits and control logic. Power input is safeguarded by an \u003cstrong\u003eInput Fuse Rating 5A\u003c\/strong\u003e and fast-acting warning fuses of types \u003cstrong\u003eSMP32\u003c\/strong\u003e and \u003cstrong\u003eMP50\u003c\/strong\u003e, while \u003cstrong\u003eShort Circuit Protection\u003c\/strong\u003e is handled by internal circuit breakers. Three high-capacity \u003cstrong\u003eCapacitors: 3x large electrolytic capacitors\u003c\/strong\u003e stabilize DC bus voltage during transient loads. The control assembly includes \u003cstrong\u003eDip Switches\u003c\/strong\u003e for customizable configuration and six selector switches (SW1–SW6). Signal and power wiring leverage \u003cstrong\u003eFan Motor Connections FU, FV\u003c\/strong\u003e and \u003cstrong\u003eMotor Power Connections U, V, W, E\u003c\/strong\u003e terminal blocks, plus dedicated \u003cstrong\u003eGrounding and Power Terminals\u003c\/strong\u003e for high-current conductors. Transistor switching is performed by the \u003cstrong\u003eTransistor Module Type TRM1–TRM6\u003c\/strong\u003e, ensuring efficient PWM drive performance.\u003c\/p\u003e\n\n\u003cp\u003eOperational features emphasize thermal resilience and diagnostic capability. An \u003cstrong\u003eExternal aluminum extrusion Heatsink\u003c\/strong\u003e provides optimum heat dissipation from power components, complemented by a speed-regulated 200V cooling fan. The integrated LED interface—including two digital 7-segment diagnostics—enables rapid fault identification and status monitoring onsite. Three precision trimmer potentiometers (VR1–VR3) allow fine adjustment of acceleration, deceleration, and torque limits to match diverse spindle characteristics. The drive supports both encoder and resolver feedback systems for closed-loop positioning and can function reliably up to 1000 m altitude.\u003c\/p\u003e\n\n\u003cp\u003eSystem integration is streamlined for industrial automation and rack-based enclosures, with form-factor compliance with standard machine tool cabinets. The VACII D22-A pairs directly with Okuma OSP series CNC controllers to leverage advanced spindle synchronization, real-time status reporting, and predictive maintenance features. Its modular design targets applications such as high-speed milling, precision grinding, and heavy-duty turning operations where dynamic response and reliability are critical. Compatible with a wide range of Okuma machine platforms, the drive is ideal for OEMs and end-users seeking consistent spindle control performance in complex machining processes.\u003c\/p\u003e","brand":"Okuma","offers":[{"title":"Unstocked","offer_id":51828080771373,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/VAC_Spindle_Drive_Series__01HRSRNQYZHE19GRS87X5BY7RD_96ef370e-87e2-4c71-8d83-4e4ed5dc2b50.webp?v=1760557430","url":"https:\/\/servosupplier.com\/products\/vacii-d22-a","provider":"Servo Supplier","version":"1.0","type":"link"}
