The parameters set by the device 3, as well as the resources during the operation The information during the operation includes the remaining room (ie, the time from the end of the running) and the rotating state (including the forward turn to the large L temporary V-shaped sad, reverse rotation state). The remaining time includes: Pause: Rotate the remaining time 'reverse rotation remaining time'. The control _ ^ = mode is displayed. Μ (4) dynamic mode == connected, control input to the input wheel... 丄 rotation direction control command; The generator 5 is connected such that the #2 stepping step is generated and the state 5 generates a pulse signal, and the motor is pulsating to receive the pulse signal for driving the control used in this embodiment = 7 rotation. In the case of e can be / / 疋锨Control state 'Control device 2 is also 疋,, he is suitable for the appropriate data processing equipment. The parameters of the control device 2 are set. The rotating motor of the stepping motor = speed, test time, direction of rotation, Step rotation, half step rotation, quarter point - rotation mode includes: • all the rotation directions include:=, octant-step rotation. Butterfly direction and anti-clockwise direction of rotation _ time) 'pause time ( After step 2 9 200907387 The interval before the start of the reverse rotation) and the time from the start to the end of the stepping motor of the heart type). The test time ^ the forward rotation test time, the reverse rotation test time, and the positive integer multiple of the temporary, Specifically, the test time BB g T1 "", the forward rotation test time is ΤΠ, the reverse rotation test time is D2, and the pause time is the sum (ie: T1+T2+T3) is one cycle, then 1W (T1+T2+2 where N represents the number of cycles, N is set by the actual situation; when Ν, τι τ2 Τ3 is set, the test time is based on the above formula (τ+τ2, automatically generated. = Wheel output controller 4 controls device 2 The issued control command passes: "Into the motor drive 6. The control command includes: a rotation direction and a rotation mode. The waveform generator 5 is configured to generate a pulse signal (4) a pulse signal of the waveform generator 5 to drive the stepping horse into two - the pulse signal corresponds to the angle of the stepping motor rotation, specifically, the wave = generator is issued each time The pulse signal stepping motor rotates two fixed angles: the setting of the pulse frequency of the waveform generator 5 through the input device 3 can control the rotational speed of the stepping motor. The example shown in Fig. 2 is a functional module diagram of the stepper motor test system of the present invention which is preferably implemented in a simple formwork. The control device 2 includes a setting module 100, a determining module 1〇1, and a processing module storage module 106. ^ And move the non-nuclear group and set the module (10) for stepping the Malay test parameters (four). The number of turns includes: stepping motor rotation speed, rotation mode, direction of rotation, and test 10 200907387 time. The rotation modes described in eight include: full-step rotation, half-step rotation mode, four-step rotation mode, and one-eighth rotation mode. The direction of rotation includes: forward rotation (may be clockwise or 曰: = direction rotation) and reverse rotation (just opposite to forward rotation; the test time refers to the forward rotation test time (direction) The time used during the rotation), the sum of the reverse rotation test time (the time used by the stepping motor, the period of time) and the pause time (the interval between the stepping motor and the smuggling: == (four)). The time, the reverse rotation test time, and the positive multiple of the pause time. Specifically, the test time is η, and the sum of the two forward rotations between the reverse rotations (TUT2+Tm/between Τ2 pause time is Τ3) , where Ν represents the number of cycles ^ by the cycle of the cycle 'then: (four) milk claws), (10) after the two conditions set; when ..., automatically generated. According to the above formula (τ = ν * (τι + ΊΓ + Τ 3)) bundle, Whether the time set by the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Then test time. Specifically: whether it is a positive time The beam, such as forward rotation (10) = the breaking module 101 determines that the forward rotation ends to the waveform generator 5, 15, 5, the time is over, the processing module 102, two 1, so that it stops the stepping motor driver 200907387 6 The pulse signal is generated to stop into the pause state; if the time is not yet 1, and 7, the stepper motor 7 indicates that the stepping motor 7 fails. The 7 stops rotating, the second module 1〇° setting After the parameter is completed, the control command is transmitted to the stepping horse to determine the forward test time: = beam ==, the judgment module is not finished, the stepping motor 7 stops rotating, and the rotation test time is up to 7 unqualified. The forward rotation shows that when the stepping horse group ends and the waveform is generated _ 5, the processing mode drive generates a pulse signal, thereby stopping the pair: entering = stepping motor into the motor 7 into the pause state; 7 drive, step-to-wheel input controller 2 = end control mode, the control command = reverse rotation, rotation mode control waveform generator 5 to generate pulse; work motor driver 6, the same step The motor driver 6 drives the pulse signal to transmit and rotate The test time has not ended yet, and the reverse rotation is performed; if the reverse preparation 1 indicates that the stepping motor 7 is unqualified, and 7 is rotated, the display indicates whether the test time is "end of trial", and 102 ends to the waveform generator 5 m is not,,,. bundle, then the processing driver 6 generates a pulse signal °, thereby;:: it stops the stepping horse stepping motor 7 into the pause ^ to the stepper motor 7 drive, the state is 'in the pause time Stepping motor 12 200907387 Returns the forward rotation step; if the test time is over and the test is over, the display device 1 prompts the stepping motor 7 to pass. The display module 104 is used to acquire the parameters set by the setting module 100 and display during the test. The status information of the operation, and the parameters set by the input device 3 and the status information displayed during the test are displayed through the display device 1, and the status information of the operation refers to the remaining test time. The storage module 106 is configured to save the set parameters when the setting module 100 sets the test end. After the test is completed, the storage module 106 saves the set parameters to the control device 2, and saves the parameters stored in the control device. As the default parameter at the time of the next test. In addition, if the user needs to reset the parameters, it can be set through the input device 3, and the storage module 106 will save the newly set parameters and overwrite the previous parameters. Referring to Figure 3, there is shown a flow chart of a preferred embodiment of the stepper motor test method of the present invention. First, in step S10, the setting module 100 sets the test parameters. The display module 104 displays the set parameters through the display device. The storage module 106 saves the set parameters and uses the saved parameters as the default parameters for the next test. The storage module 106 retains only the parameters of the latest setting. The parameters include: stepper motor test time, rotational speed, rotational direction, and stepper motor rotation mode. The test time includes: forward rotation test time (time used during forward rotation of the stepping motor), reverse rotation test time (time used during reverse rotation of the stepping motor), and pause time (stepping motor forward rotation) The sum of the intervals between the start of the reverse rotation after stopping.
