Design Consideration4.1 OverviewThe controller board is designed for demonstration of the ability of Freescale MPC5604P MCU to control various electrical motors and for easier development of the motor-control applications. In addition to the hardware needed to run a motor, a variety of feedback signals that facilitate control-algorithm development are provided. A set of schematics for the controller board appears in the following section.4.2 MPC5604PThe MPC5604P is the first member of family of microcontrollers based on Power Architecture TM, targetted at chassis and safety market segment, specifically at lower-end Electrical Power Steering and airbag-application market space. The used core is the Harvard-bus interface version of the e200z0.The MPC5604P has a single level of memory hierarchy consisting of 40 kByte on-chip SRAM, 512+64kByte of on-chip Flash memory. Both SRAM and Flash memory can hold instruction and data. The timer functions of MPC5604P are performed by the eTimer — Modular Timer System and FlexPWM. The two eTimer modules implement enhanced timer features (six channels each for a total of 12) including dedicated motor-control quadrature-decode functionality and DMA support; FlexPWM module consists of four submodules controlling a pair of PWM channels each; three submodules may be used to control the three phases of a motor and the additional pair to support DC-DC converter width modulation control. Off-chip communication is performed by a suite of serial protocols including FlexRay, CANs, enhanced SPIs (DSPI), and SCIs (LinFlex).The System Integration Unit Lite (SIUL) performs several chip-wide configuration functions. Pad configuration and General-Purpose Input and Output (GPIO) are controlled from SIUL. External interrupts and reset control are also found in the SIUL. The internal Multiplexer sub-block (IOMUX) provides multiplexing of daisy chaining the DSPIs and external interrupt signal.You can find detailed description of the MCU in the datasheet or reference manual.Figure4-1 MCPC5604P Block Diagram4.3 Clock SourceThe MPC5604P uses external 8.00 MHz crystal oscillator mounted on the board and internal PLL0 to multiply the input frequency, to achieve its 64 MHz maximum operating frequency. The second PLL1 is used to achieve suitable frequency for internal FlexRAY module. The MPC5604P can also use internal 16MHz RC oscillator as clock source, in this mode FlexRAY protocol clock does not support IRCOSC as a clock source.4.4 UNI3 Interface and External Fault ManagementThe motor power stages are controlled by microcontroller boards through UNI3 and MC33937 connectors. The connector pin description was mentioned before in Section3. Pin Description. Analog or digital signals from the power stage can be proccesed by hardware to maintain fault management. The MPC5604P has four fault inputs that input to the PWM module and switch off PWM output signals. The FAULT0 signal can be set up as under- or over-voltage. Whether the output signals from Phase A or DCBUS over-current comparator can be asserted to the input Fault1, depends on jumper position J301. The FAULT2 and FAULT3 MCU inputs can be used as over-current signals from phase B and C. The phase OC level is set up by trimmer R300, as you can see in Figure4-2.Figure4-2 FAULT Managment4.5 Encoder InputsThe controller board can read position or speed from up to two independent encoders. The first one can be connected to the JP500 connector. The encoder interface consists of the signal-level modification block and jumpers. A large amount of encoder sensors are powered from +5 V DC supply voltage and output signals are in the same voltage level. This block provides signal-level modification.Figure 4-3 Encoder Input CircuitTable 4-1 Header J301 — FAULT1 Signal AssignmentJumper position Description 1–2Phase A over-current.2–3DC-bus over-current.4.6 Resolver and SINCOS SensorThe resolver and SINCOS signals are included to observe motor rotor position. Figure4-4 shows hardware circuitry. The resolver sensor can be connected through J207 connector. The jumpers J203 and J204 provide positive input to differential amplifiers. For resolver sensor use, pins two and three should be shorted. The output RES_GEN signal level is set up by trimmer R221. For detailed description, see application note AN1942 or patent WO/2007/137625.Figure4-4 Resolver Schematic4.7 Analog Signal SensingThe MPC5604P can sample up to 2×16 analog signals. External 2×11 channels are connected through RC filters directly to ADC converters zero and one, next four channels are common and can be internally switched between both converters. They can be used to sample phase motor currents. The ADC0 channel 15 is dedicated for internal 1.2 V rail, and ADC1 channel 15 for the temperature sensor.The time constant of RC filter should be set according to system requirements. The default time constant was set to approximatelly 1.2 μs on the inputs zero to ten, and shared inputs are set to approximately 50 ns.。

福禄克55XX系列校准器使用方法55XX系列校准器包括新型号5080A,5502A,5522A,以及过去的旧型号的5502A和5522A。
它们的主要功能有如下几项:· 直流电压±(0~1020) V· 沟通电压1.0 mV~1020 V (1Hz~1MHz)· 直流电流±(0~20.5) A· 沟通电流29 mA~20.5 A, (1Hz~1MHz)· 电阻0 W~1100 MW以往,许多试验室校准这些多产品校准器的方法,就是使用8508A 八位半高精度数字多用表直接测量。
一台8508A真的就能够完成55XX系列校准器的校准吗?我们必需对不同的型号做详细的分析。
在5500A、5502A、5520A、5522A的维护手册中,对这些仪器的校准要求和校准方法作了具体说明。
尤其是提出了各个功能的校准调整点。
只有保证这些校准调整点的精确度,才能保证仪器各个功能全范围的性能。
当检查仪器性能时,应当尽量包含这些校准调整点。
假如发觉校准器精确度下降,必需通过调整这些点来恢复仪器的精确度。
这里,我们以精确度指标较低的5502A为例,根据5502A说明书建议的各个校准调整点,实际计算每个校准点的测量不确定度,分析用什么样的标准设备可以校准5502A。
我们会发觉,有许多功能,尤其是电流测量功能,8508A并不能满意校准多产品校准器的精确度要求。
1. 直流电压校准依据5502A维护说明书,5502A直流电压除零点外,设有八个校准调整点。
在各校准调整点上,我们计算出5502A的总不确定度,8508A 的直流电压测量功能的总不确定度,计算结果列于表1中。
从表1可以看出,8508A直流电压的性能特别优异,在全部5502A直流电压校准调整点上,5502A直流电压的总不确定度与8508A总不确定度的比率TUR都大于7,可以满意校准的基本要求。
因此,可以用8508A的直流电压测量功能直接校准5502A的直流电压输出功能。
