Designed for a wide input range of \u003cstrong\u003eAC170V-AC250V\u003c\/strong\u003e at \u003cstrong\u003e50\/60Hz\u003c\/strong\u003e, the drive accommodates diverse industrial power environments. It employs \u003cstrong\u003esix power transistors\u003c\/strong\u003e for efficient switching and power regulation, and features a \u003cstrong\u003ePT768 main diode module\u003c\/strong\u003e rated at \u003cstrong\u003e75A 800V\u003c\/strong\u003e to manage rectification with minimal loss. Complementing this, the drive supports interchangeable transistor modules—\u003cstrong\u003eEVM31-050A or QM150DX-H\u003c\/strong\u003e—each rated at \u003cstrong\u003e150A 600V\u003c\/strong\u003e or \u003cstrong\u003e150A 450V\u003c\/strong\u003e for application flexibility. The primary protection is handled via a \u003cstrong\u003eBase Circuit Fuse Type KM10 1A\u003c\/strong\u003e, supplemented by \u003cstrong\u003eWarning Fuse Type 1 SMP32 3.2A\u003c\/strong\u003e and \u003cstrong\u003eWarning Fuse Type 2 MP50 5A\u003c\/strong\u003e to guard against overcurrent events.\u003c\/p\u003e\n\n\u003cp\u003ePerformance and technical integration are streamlined through the onboard \u003cstrong\u003eVAC-BOARD-II\u003c\/strong\u003e control PCB, which orchestrates drive functions with precision. Control signals are routed through a \u003cstrong\u003eCN1 (50-pin) connector\u003c\/strong\u003e while motor feedback and power are interfaced via a \u003cstrong\u003eCommercial MATE-N-LOCK 1-480438-0 (16-pin) motor signal connector\u003c\/strong\u003e. The board architecture integrates a regeneration circuit that captures braking energy, a transformer for localized voltage conversion, and visual diagnostics delivered by LED indicators. Configurable settings are facilitated by DIP switches, allowing field customization of operational parameters, while the drive’s \u003cstrong\u003epotentiometer adjustments\u003c\/strong\u003e (Speed Meter and Load Meter) give technicians real-time tuning capability. This combination of high-current transistor modules, robust diode rectification, and advanced PCB topology ensures stable and responsive spindle control under dynamic loads.\u003c\/p\u003e\n\n\u003cp\u003eReliability is enhanced by carefully selected signal connectors and robust PCB components that meet stringent Industrial Automation standards. The VAC D8-B seamlessly integrates into existing CNC architectures, leveraging standardized \u003cstrong\u003eSignal connectors\u003c\/strong\u003e and modular drive design to minimize installation complexity. Its resilience under continuous operation is assured by protective fusing and regenerative energy handling, extending component life and reducing maintenance intervals. Tailored for precision machining, the drive excels in demanding applications such as milling, drilling, and turning within high-volume production and Wake industrial environments. By balancing advanced technical features with practical ease of use, the VAC D8-B ensures consistent spindle performance and maximizes equipment uptime.\u003c\/p\u003e","brand":"Okuma","offers":[{"title":"Unstocked","offer_id":52095295717677,"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_df2cb88d-67f1-4819-a37a-1a6cd5253bb0.webp?v=1757419912","url":"https:\/\/servosupplier.com\/products\/vac-d8-b","provider":"Servo Supplier","version":"1.0","type":"link"}
