The unit supports a \u003cstrong\u003erated revolution speed of 2000 rpm\u003c\/strong\u003e and a \u003cstrong\u003emaximum revolution speed of 2500 rpm\u003c\/strong\u003e, enabling both high-speed indexing and steady-state positioning. Equipped with a \u003cstrong\u003etorque constant of 1.05 N·m\/Arms (10.7 kg·cm\/Arms)\u003c\/strong\u003e and an \u003cstrong\u003einduced voltage constant of 36.7 mV\/min⁻¹ (36.7 V\/krpm)\u003c\/strong\u003e, this amplifier ensures efficient energy conversion and precise torque generation. With a lightweight inertia of \u003cstrong\u003e58.1×10⁻⁴ kg·m² (59.1 g·cm·s²)\u003c\/strong\u003e it minimizes system overshoot and simplifies tuning for fast start-stop cycles. The housing features a compact, rectangular design with multiple terminal connectors for seamless integration.\u003c\/p\u003e\n\n\u003cp\u003ePerformance characteristics of the PYRA1111001 include advanced electrical and mechanical dynamics to optimize motion control loops. The \u003cstrong\u003emechanical time constant of 0.68 ms\u003c\/strong\u003e and \u003cstrong\u003eelectrical time constant of 33 ms\u003c\/strong\u003e provide rapid response to command changes, while the \u003cstrong\u003ephase armature resistance of 0.043 Ω\u003c\/strong\u003e contributes to stable current regulation. Continuous stall capacity is rated at \u003cstrong\u003e31.6 Arms\u003c\/strong\u003e with a \u003cstrong\u003econtinuous stall torque of 32.0 N·m (326 kg·cm)\u003c\/strong\u003e, while peak demand is supported by an \u003cstrong\u003einstantaneous maximum stall armature current of 79.7 Arms\u003c\/strong\u003e and \u003cstrong\u003einstantaneous maximum stall torque of 70.0 N·m (714 kg·cm)\u003c\/strong\u003e. A \u003cstrong\u003erated armature current of 24.1 Arms\u003c\/strong\u003e ensures sustained performance under heavy loads. The built-in regenerative resistor and regenerative processing circuit absorb excess energy during deceleration, and dynamic brake activation secures safe shutdown in power loss or alarm conditions. Switching between \u003cstrong\u003eposition, speed, and torque control\u003c\/strong\u003e modes is possible on the fly, utilizing pulse train or analog input interfaces, and compatibility with ABS-R II and ABS-E sensors enhances feedback precision.\u003c\/p\u003e\n\n\u003cp\u003eReliability and integration are hallmarks of the PYRA1111001 design. The amplifier incorporates \u003cstrong\u003einrush current limiting\u003c\/strong\u003e to prevent power-on surges and features internal auto-tuning for optimized PID loop parameters, reducing commissioning time. Separation of control power and main circuit power ensures that, in an emergency stop or alarm state, diagnostics and alarm outputs remain active while the main drive power is isolated. A dedicated \u003cstrong\u003eholding brake excitation timing output\u003c\/strong\u003e safeguards the connected motor brake mechanism, enhancing safety in vertical or high-inertia applications. Compact dimensions and multiple I\/O connectors facilitate system integration in industrial automation, robotics, and CNC machinery where precise, dynamic motion control and dependable operation are essential.\u003c\/p\u003e","brand":"Sanyo Denki","offers":[{"title":"Refurbished","offer_id":51889048092973,"sku":null,"price":2922.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/PY_Super_BL_Servo_Amplifiers__6f189110-9f28-4220-a59b-b576a1760a7c.webp?v=1760469537","url":"https:\/\/servosupplier.com\/products\/pyra1111001","provider":"Servo Supplier","version":"1.0","type":"link"}
