The kit consists of two boards: a controller board and a drive board. The system incorporates high quality power sources reliable power, control, and feedback signals isolation accurate measurement of motor current & voltage signals high speed interfaces for control signals to allow fast controller response industrial Ethernet high speed interfaces single ended Hall, differential Hall, encoder and resolver interfaces digital position sensors interface flexible control with a FPGA/SoC interface. Two motors can be driven at the same time, each motor having its separate power supply. The AD-FMCMOTCON2-EBZ is a complete high performance servo system on an FPGA Mezzanine Card (FMC) board, the purpose of which is to provide a complete motor drive system demonstrating efficient and high dynamic control of three phase PMSM and induction motors up to 48V and 20A. This evaluation board is obsolete and no longer recommended. Unlike other optocoupler alternatives, the ADuM1400 / ADuM1401 / ADuM1402 isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and when power is not applied to one of the supplies. In addition, the ADuM1400 / ADuM1401 / ADuM1402 provide low pulse width distortion (<2 ns for CRW grade) and tight channel-to-channel matching (<2 ns for CRW grade). All models operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. The ADuM1400 / ADuM1401 / ADuM1402 isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide in the data sheet). Furthermore, iCoupler devices consume one-tenth to one-sixth of the power of optocouplers at comparable signal data rates. The need for external drivers and other discrete components is eliminated with iCoupler products. The typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with the simple iCoupler digital interfaces and stable performance characteristics. Combining high speed CMOS and monolithic air core transformer technology, this isolation component provides outstanding performance characteristics superior to alternatives, such as optocoupler devices.īy avoiding the use of LEDs and photodiodes, iCoupler devices remove the design difficulties commonly associated with opto-couplers. The ADuM1402 is a quad-channel digital isolator with 2/2 channel directionality based on Analog Devices, Inc., iCoupler ® technology.
