Other platforms may work with standard baud rates, but this operation has not yet been verified.Motor Control LimitationsFollowing are the known limitations for this release of motorBench® Development Suite:1. One mechanical load - constant load. This represents a mechanical load with constant inertia, viscous damping, and friction. The velocity control loop can generally rejectexternal disturbance torques, within the rated current of the motor and board, and within the bandwidth of the velocity control loop. Mechanical loads with time-varying or angle-varying inertia, viscous damping, and friction, such as a blower, compressor, or pump, are currently not supported.2. One motor type - PMSMMCLV-2:The reference motor is the Nidec Hurst motor DMA0204024B101 (MicrochipDirect part number AC300022). Microchip has also validated motorBench® DevelopmentSuite (including motor parameter measurement) with motors with parameters plotted below. Please also read the following section on Supported Motor Parameters. IfmotorBench® Development Suite is unable to spin a motor successfully, please contact Microchip staff for additional assistance.(Note: Mechanical time constant (2/3)×JR/Ke² represents the time constant of velocity acceleration under an open-loop synchronous-frame voltage step, neglecting the effects of inductance, with J, R, and Ke expressed in canonical metric units. R is expressed as line-neutral resistance = half of line-line resistance, and Ke is expressed as V/(rad/s) line-neutral zero-peak = Vrms/KRPM (line-line) × 0.007796968)MCHV-2/MCHV-3:The reference motor is the Leadshine 400W motor EL5-M0400-1-24 (MicrochipDirect part number: AC300025). Microchip has validated motorBench® DevelopmentSuite (including motor parameter measurement) with motors with parameters plotted below. Please also read the following section on Supported MotorParameters. If motorBench® Development Suite is unable to spin a motor successfully, please contact Microchip staff for additional assistance.3. Boarda. dsPICDEM™ MCLV-2 development board. This release of motorBench® Development Suite is compatible with modifications to the board to alter its rated current orvoltage. Contact your local Microchip office to obtain the document "Using MCLV-2 with motorBench® Development Suite to support alternative current and/or voltageratings", which provides guidance for such modifications. Other modifications may not be compatible.b. dsPICDEM™ MCHV-2 and MCHV-3 development boards. This release of motorBench® Development Suite is compatible with unmodified MCHV-2 and MCHV-3development boards.4. Motors should be well-matched to the board and operating voltage. The nominal DC link voltage of the MCLV-2 board is 24V. This voltage can be changed by cutting jumperJ6 and using an appropriate power supply connected to the appropriate terminals of J7. Use of a mismatched motor (for example, a 12V motor used with a 24V DC link voltage) may cause a hardware over-current fault; in this case motor parameter measurement may fail with the message "Fault Code #10: Undefined Fault". Retry with an appropriate DC link voltage.5. Two PIMs and Two devices - dsPIC33EP256MC506 External OpAmp PIM with silicon revision A8 or dsPIC33CK256MP508 External OpAmp PIM. (Please see the HardwareSetup section of the motorBench User's Guide for important modifications to dsPIC33EP256MC506 External OpAmp PIM for use in MCHV-2 and MCHV-3.)6. One algorithm - FOC7. Estimators - PLL, QEI, ATPLL8. Motor parameter measurement:a. Performance criteria adjustment is not presently supported. This includes adjustment of phase margin and PI phase lag at crossover in the current loop; Microchip hasnot completed validation and documentation of these adjustments.9. Autotuning:a. Performance criteria adjustment of the current loop is not presently supported. This includes adjustment of phase margin and PI phase lag at crossover; Microchiphas not completed validation and documentation of these adjustments.b. Use of performance criteria adjustment of the velocity loop is not fully documented or tested. We recommend not adjusting phase margin or PI phase lag unlessnecessary; cases where this is likely to occur are large inertias where αJ = JR/LK m2 > 10, for which an increase of phase margin is appropriate. Phase margin valuesbetween 70 and 85 degrees are recommended in this case, with larger values providing additional stability at the cost of lower velocity bandwidth.10. Axis management not currently implemented - supports only one axis.11. Code generation:a. PWM switching frequency is fixed at 20kHz and does not reflect the value entered under Board parametersb. Integration with external user-supplied code may involve substantial changes. Some guidelines for this are given in the documentation for the Motor ControlApplication Framework. While it is possible to integrate the code generated from motorBench® Development Suite with external code, it is the responsibility of the end user to validate this combination.12. Required compiler settings:a. Optimization-O1 or greater; -O0 and -Os will both compile without errors but do not execute fast enough to complete within the 50 microsecond ADC ISR. Note: at higheroptimization levels, in-circuit debugging using MPLAB X will behave unreliably with respect to breakpoints and single-stepping through C code.The "Omit frame pointer" and "Unroll loops" settings must be enabled.b. Memory model:Large data model (handles using pointers, not direct addressing, to allow for more than 8K of program variables)Small scalar modelc. Additional options:-Wno-volatile-register-var -finlined. Test harness: In order for the test harness to be enabled, the symbols MCAF_TEST_PROFILING and MCAF_TEST_HARNESS should be defined.13. Recommended compiler settings:a. Additional options:-WundefSupported Motor ParametersSince version 2.15, motorBench®Development Suite supports a wide range of motors, subject to the following notes:Ranges of motor parameters (including rated values and computed metrics) must be within the limits noted in either range-limits-mclv2.html or range-limits-mchv2.html.These ranges were tested to ensure that code generation produced firmware constants that were within bounds.Motor parameter measurement does not need to complete successfully but valid motor parameters are required. Some motors may have too low of an inductance or resistance, and may fail motor parameter measurement.Other particular issues that may cause incompatibility with motorBench®Development Suite includeLarge inertia values – in this case, increasing voltage loop phase margin may prevent stability problems. (See "Autotuning" in the Limitations section of this document.) Rotor magnetic saliency – if there are significant differences between Ld and Lq (>10% difference) then some of the MCAF algorithms may not work optimally. Highermismatch between Ld and Lq is typically found in interior-permanent magnet (IPM) motors, and is an intentional feature of the design. See the MCAF User's Guide for more information.Large back-EMF harmonics – a quasi-sinusoidal back-emf is assumedIssues involving individual motor control algorithms, such as PLL estimator, motor startup, or stall detectionHigh cogging torqueMismatch between motor and drive (namely using a motor with current and/or voltage requirements significantly different from that of the hardware) Microchip cannot guarantee that motorBench®Development Suite will work correctly with all motors. If a particular motor does not work properly, please contact the MCU16 Motor Control Team for further guidance.Customer SupportThe Microchip Web SiteMicrochip provides online support via our web site at .

How often we find that the foreigners whom we thought to be such different people from ourselves are not very different at all!Differences between peoples do，of course，exist and，one hopes，will always continue to do so.The world will be a dull place indeed when all the different nationalities behave exactly alike，and some people might say that we are rapidly approaching this state of affairs.With the much greater rapidity (快速) and ease of travel，there might seem to be some truth in this at least as far as Europe is concerned.However this may be，at least the greater ease of travel today has revealed (展示) to more people than ever before that the Englishman or Frenchman or German is not：some different kind of animal from themselves.5．Every country criticizes ways of life in other countries becau se they are_____.A．distorted B．normalC．similar to each other D．different from its own6．One who travels in a foreign country and learns its language will________. A．find out why its people are differentB．argue in favor of this country and the languageC．know the country and its people betterD．like its inhabitants and their language7．The knowledge one gains by traveling in a foreign country is often________. A．from second-hand informationB．gathered from other sources rather than its inhabitantsC．gained from the arguments about the countryD．different from what one had before the travel8．In this passage，th e author wants to say________.A．differences between peoples will gradually disappear because of the ease of travelB．differences between peoples do exist even though different nationalities behave exactly alikeC．differences between peoples will continue to exist and the world will be a dull placeD．differences between peoples will not exist as one hopes参考答案Ⅰ.语音知识1．B 2.B 3.D 4.A 5.CⅡ.情景对话1．F 2.E 3.B 4.G 5.DⅢ.单项填空1．A available可利用的，常跟在修饰词的后面；其他三项“qualified合格的；standard标准的；impressive印象深刻的”作定语常放在修饰词之前，且与题意不符。
