Problems solved by technology

Each state change needs to be input and sent according to a specific command format defined in advance. When the state of the motor needs to be changed rapidly and continuously, continuous and rapid multiple inputs cannot be realized, and the verification speed of this verification scheme is relatively slow, semi-manual control Does not meet automation needs

Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] Such as figure 1 Shown, the stepping motor driver chip functional verification system of an embodiment of the present invention, man-machine interface, control board, the driver board that is provided with stepper motor driver chip slot and stepper motor man-machine interface, control board, driver board And the stepper motor is connected in turn.

[0038] The human-machine interface is used to input verification parameters and commands, the control board is used to generate pulse signals, direction signals and enable signals, and the driver board is used to plug in the stepper motor driver chip to be verified. The enable signal drives the stepper motor to verify the function of the stepper motor driver chip to be verified.

[0039] Using the stepping motor driver chip function verification system of this embodiment, when performing chip function verification,...

Abstract

The invention provides a stepping motor drive chip function verification system which comprises a man-machine interface, a control panel, a drive panel and a stepping motor. The drive panel is used for setting a slot of a stepping motor drive chip. The man-machine interface, the control panel, the drive panel and the stepping motor are sequentially connected. The stepping motor drive chip to be verified is inserted into a socket of the drive panel, and the stepping motor is driven so that the function of the stepping motor drive chip to be verified can be verified. According to the stepping motor drive chip function verification system, the basic function can be verified, and the accurate stepping function of the stepping motor drive chip can also be verified; by replacing the drive panel suitable for different types of stepping motor drive chips, the functions of the different types of the stepping motor drive chips can be verified; in the verifying process, connecting wires of the stepping motor drive chip do not need to be changed, the function of the stepping motor drive chip can be verified only by sending out a verifying order through the man-machine interface, and therefore the efficiency of verifying the function of the stepping motor drive chip is improved.

Description

technical field [0001] The invention belongs to the field of chip verification, in particular to a stepping motor drive chip function verification system. Background technique [0002] The stepper motor converts the received electric pulse signal into linear displacement or angular displacement. It operates in a single step at a fixed angle in a fixed mode, has no accumulated error, and has high precision, and has more and more applications in the field of automation. However, DC or AC power cannot directly act on the stepping motor, and a special stepping motor driver board must be used to drive the stepping motor to work normally. [0003] The stepper motor driver chip is used as the driver board, through the circular distribution and power amplification of the input pulse, so that the stepper motor windings are energized in a certain order. When the stepper motor driver board receives a pulse signal, it drives the stepper motor according to the setting. Rotate by a fixe...
