Detailed description of the invention
About aforementioned and other technology contents, feature and effect of the present invention, coordinate with reference to graphic one better followingIn the detailed description of embodiment, can clearly present. The direction term of mentioning in following examples, for example: upper and lower, left,Right, front or rear etc., be only the direction with reference to annexed drawings. Graphic all genus signal in the present invention, is mainly intended to represent each deviceAnd function relation between each element, as for shape, thickness and width not according to scale.
With reference to Fig. 2 and Fig. 3, in motor controller 20 of the present invention, comprise a control module 21, a motor drive unit 22,An and rotating speed converting unit 23; In rotating speed converting unit 23, comprise erasable internal memory 231 for storing the relevant of motor characteristicsData. Motor controller 20 comprises multiple pin position, for example, comprise PWMIN, H+, H-, FG, VM, OUT1, OUT2, GND, these pinThe effect of position can be consulted the explanation in background technology paragraph.
The difference of the present invention and prior art is: the present invention does not need for receiving motor characteristics burning data and receive frequencyAnd ad hoc pin position SDA, SCK; Share these pin positions and other pin position. (data and other pin that transmit for distinguishing pin position SDAPosition signal that such as PWMIN, H+, H-, FG etc. transmit, below data that pin position SDA is transmitted be called motor characteristics burningData, although and the signal that transmit other pin position also has the character of data, be not called " motor characteristics burning data ". ) because ofThe function of pin position SDA and SCK is that burning before motor (not shown) starts (input or setting) motor characteristics data are erasable in oneIn internal memory 231, therefore only need to operate under burning pattern. When under normal mode, when motor starts to operate, pin position SCK and SDA are notNeed to transmit, therefore substantially except the pin position relevant with ground connection with the power supply of motor controller 20 itself, allOther pin position can be shared with pin position SDA, SCK. That is, if the power supply of motor controller 20 is not from pin position VM and yet, by pin position GND ground connection, in PWMIN, H+, H-, FG, VM, OUT1, OUT2, GND, conduct can not shared in any two pin positionsPin position SDA, SCK; If the power supply of motor controller 20 is from pin position VM and also by pin position GND ground connection, except these two pinOutside position, in PWMIN, H+, H-, FG, OUT1, OUT2, any two pin positions can be shared as pin position SDA, SCK. The present invention is with twoIndividual embodiment illustrates, is shown in Fig. 2 and Fig. 3, and wherein for Fig. 2 embodiment, pin position PWMIN, FG share as pin positionSDA, SCK, for Fig. 3 embodiment, pin position OUT1, OUT2 share as pin position SDA, SCK, and this is only for lifting wherein two examples, as aboveDescribed, any two pin positions can be shared as pin position SDA, SCK.
With reference to Fig. 2, when normal mode, pin position FG, PWMIN need to transmit; When burning pattern, pin position SCK and SDA needTransmit, pin position FG and PWMIN can not need to transmit. Therefore in the present embodiment, pin position SCK and SDA andPin position FG and PWMIN can share its pin position, for example can in the time of burning pattern, transmit frequency with pin position FG and with pin position PWMIN comeTransmit motor characteristics burning data. Certainly, also can use that pin position FG transmits motor characteristics burning data instead and with pin position PWMINTransmit frequency.
Erasable internal memory 231 in rotating speed converting unit 23 can be according to above-mentioned frequency and motor characteristics burning data, andStore motor characteristics data in the inner, its mode can be for example: in erasable internal memory 231, stored in advance all kindsMotor characteristics data, and by transmitted motor characteristics burning data set adopt which group in advance store motor characteristicsData; Or, also can in erasable internal memory 231, input motor characteristics number according to transmitted motor characteristics burning dataAccording to. The object of motor characteristics data is the characteristic of the motor that manipulates of definition, for example, when pin position PWMIN accept fromThe external rotating speed control signal of one PWM form, rotating speed converting unit 23 can convert this external rotating speed control signal to a numeralNumerical value, and this digital numerical value is through producing a motor speed command to control module 21 with reference to motor characteristics data. Control module21 can accept motor speed command and from outside motor rotary speed sensing signal H+, H-(motor rotary speed sensing signal H+, H-For example, but not necessarily from Hall element, also can be for example from optics rotating speed sensing apparatus etc.). Control module 21 is accepted motorAfter speed command and motor rotary speed sensing signal H+, H-, can learn motor speed command and existing rotating speed, and then output horseReach control signal, control motor drive unit 22 and drive controlled motor to arrive set rotating speed.
Please refer to Fig. 4, the switching flow of burning pattern and normal mode is described. After startup, can be by default pin position is defeated arbitrarilyEnter specific signal and begin to enter burning pattern (step S1) to open, for example, in Fig. 2 embodiment, pin position FG can be pulled low toLow level, or by a cognizable specific signal of any one pin position input, switch one such as but not limited to high-low-position is accurateInferior or repeatedly etc. In the present embodiment, in the time that control module 21 picks out this specific signal, for example, detect pin position FG and be pulled low toLow level, determines that sharing pin position is provided as pin position SCK and SDA, with transmission frequency and motor characteristics burning data (stepS2). In step S3, the no burning pattern of leaving is answered in control module 21 judgements, and its judgment mode has variety of way, can be as requiredDesign, for example can calculate one section of Preset Time, leave burning pattern and enter normal mode when arriving timing time(step S4), or input specific signal by presetting arbitrarily pin position, for example pin position FG can be drawn high to high levels one segment lengthTime, or also can be the accurate signal that switches one or many of aforementioned high-low-position etc., in the time picking out this specific signal, leave burningRecord pattern and enter normal mode (step S4). After entering normal mode, shared pin position is switching to the pin of normal modePosition, for example, in Fig. 2 embodiment, revert to pin position FG and PWMIN.
Fig. 3 shows the motor controller 20 of another embodiment, wherein shares as pin position with pin position OUT1, OUT2SDA, SCK, its operating process is identical with Fig. 4, repeats no more.
Erasable internal memory 231 for example can be (but being not limited to) one time programmable read-only storage, muptiple-use canProgrammable read-only memory, can erase programmble read only memory PROM or flash memory etc.
Motor controller can be for example (but being not limited to) stepping motor controller.
Below for preferred embodiment, the present invention is described, the above, only for being easy to those skilled in the artSeparate content of the present invention, be not used for limiting interest field of the present invention. For those skilled in the art, when can be in essence of the present inventionIn god, think immediately and various equivalence variation. For example, the enforcement of shared pin position can be not limited to transmit data and transmission frequencyShared pin position, the initialization directive signal of other such as parameters of hydraulic motor, detect the receipts of not bothering to see me out such as instruction signal under normal modeThe patented technology of this shared pin position also can be applied to simplify pin number order in the pin position of signal. Again, shared pin position is not limited to pinPosition SCK and SD are all shared, also should belong to scope of the present invention as only shared one of them. Therefore all according to concept of the present invention and spiritual instituteImpartial variation or modification, all should be included within the scope of claim of the present invention for it.
