When a high-inertia motor decelerates rapidly, it acts as a generator, feeding kinetic energy back into the drive system. This module intercepts that regenerative energy at the DC bus tier, safely redirecting and dissipating the excess electrical energy into external braking resistors to protect the primary inverter electronics from catastrophic overvoltage faults.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel Number\u003c\/td\u003e\n\u003ctd\u003e6SE7032-1HB87-2PA1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eSiemens\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Series\u003c\/td\u003e\n\u003ctd\u003eSIMOVERT MASTERDRIVES\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent Typology\u003c\/td\u003e\n\u003ctd\u003eDynamic Braking Module (Chopper Circuit)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eGermany\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Weight\u003c\/td\u003e\n\u003ctd\u003eApproximately 7.5 kg (16.5 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage Window\u003c\/td\u003e\n\u003ctd\u003e890 V DC to 930 V DC (Nominal DC Link Range)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContinuous Power Rating\u003c\/td\u003e\n\u003ctd\u003e200 kW peak braking capacity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure Protection Class\u003c\/td\u003e\n\u003ctd\u003eIP20 rated chassis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMechanical Mounting Profile\u003c\/td\u003e\n\u003ctd\u003eVertical panel-mounted configuration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Lifecycle Status\u003c\/td\u003e\n\u003ctd\u003e\n\u003cstrong\u003eDiscontinued\u003c\/strong\u003e (Global product milestone reached September 30, 2020)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnvironmental Compliance\u003c\/td\u003e\n\u003ctd\u003eNon-RoHS-compliant architecture\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eDrive Braking Modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eIndustrial Control \u0026amp; Drive Communications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Bus Voltage Monitoring and Chopper Activation\u003c\/strong\u003e The braking module contains an autonomous hardware tracking circuit that samples the common-mode voltage across the VFD's internal DC link. The moment the regenerative energy forces the link potential above the 890–930 V DC threshold, the internal solid-state chopper switches (IGBTs) activate parallel to the drive's primary logic loop, creating an auxiliary load path without adding latency to the main controller's fieldbus processing tracks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Scaling and Inverter Matrix Isolation\u003c\/strong\u003e The architecture is built to absorb heavy thermal and electrical loads during aggressive machinery braking cycles. By isolating the high-current resistor loop from the low-voltage internal command gates, the 200 kW module protects sensitive memory chips and controller boards from the severe electrical noise and voltage fluctuations typically caused by heavy inductive braking.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What specific drive error codes manifest on the MASTERDRIVES operator panel if this module fails open?\u003c\/p\u003e\n\u003cp\u003eA: If the chopper circuit fails to activate when the motor regenerates, the DC link voltage will spike instantly.
