As a cornerstone of the ACOPOSmulti motion control ecosystem, this unit is designed to handle high-precision motor control in demanding industrial environments, including packaging machinery, robotics, and complex CNC applications. This module operates on a nominal DC bus voltage of 750 VDC, providing the power density and rapid response times required for multi-axis synchronization. By optimizing energy efficiency through sophisticated switching frequency management, it ensures reliable torque delivery while minimizing thermal losses in the cabinet.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eThe 8BVI0028HWDS.000-1 is engineered for seamless integration into the ACOPOSmulti backplane architecture. Its power consumption profile is dynamic, calculated based on the specific switching frequency and motor current ($I_M$) to maintain precise thermal control. The module includes integrated input capacitance of 23.5 µF to stabilize the DC bus voltage, protecting the drive from transients. Power management is highly scalable; the maximum power consumption is defined by the base module power (28 W) plus the specific requirements of the power supply modules (PSMC), auxiliary 24 VDC outputs, and holding brake demands, ensuring the system can be precisely tailored to the application's energy needs.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"2\"\u003eModel\u003c\/td\u003e\n\u003ctd data-row=\"2\"\u003e8BVI0028HWDS.000-1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"3\"\u003eBrand\u003c\/td\u003e\n\u003ctd data-row=\"3\"\u003eB\u0026amp;R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"4\"\u003eSeries\u003c\/td\u003e\n\u003ctd data-row=\"4\"\u003eACOPOSmulti\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"5\"\u003eNominal Voltage\u003c\/td\u003e\n\u003ctd data-row=\"5\"\u003e750 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"6\"\u003eInput Capacitance\u003c\/td\u003e\n\u003ctd data-row=\"6\"\u003e23.5 uF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"7\"\u003eWeight\u003c\/td\u003e\n\u003ctd data-row=\"7\"\u003e2.8 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"8\"\u003eMounting Type\u003c\/td\u003e\n\u003ctd data-row=\"8\"\u003eWall Mounting\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"9\"\u003eHumidity (Operation)\u003c\/td\u003e\n\u003ctd data-row=\"9\"\u003e5 to 85% (Non-condensing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003ePower Dissipation (Switching Frequency)\u003c\/h3\u003e\n\u003cp\u003eThe power loss ($P_{loss}$ in Watts) of the module varies significantly based on the selected switching frequency and motor current ($I_M$):\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e5 kHz:\u003c\/strong\u003e $1.2 \\cdot I_M^2 + 2.62 \\cdot I_M + 100$\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10 kHz:\u003c\/strong\u003e $2.56 \\cdot I_M^2 + 2.8 \\cdot I_M + 200$\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e20 kHz:\u003c\/strong\u003e $6 \\cdot I_M^2 - 9.4 \\cdot I_M + 430$\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow is the total power consumption calculated for this drive?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe total consumption is the sum of the base 28 W constant load, the power drawn by the connected PSMC modules, any external 24 VDC auxiliary loads, and the energy required to disengage\/engage the holding brakes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the switching frequency affect the drive's thermal management?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes.
