3MD883ES is a stepper motor driver with constant angular moment and high subdivision, which adopts pure sinusoidal precise current control technology. This technology can significantly improve the motor noise and smooth operation of the maximum driving current of 8.3A, the highest positioning accuracy of 64 subdivision can reach 12800 steps.
application area
Suitable for all kinds of automation equipment and instruments in the field of motion control, such as electronic processing and testing, semiconductor packaging, laser cutting and welding, laser black row, packaging machinery, engraving machine, marking machine, cutting machine, clothing plotter, numerical control machine tool, automatic assembly equipment, etc. It is the first choice in the field where users expect low noise, high speed performance and cost-effective competition.
Driver function operation instructions
1) Micro-step subdivision number setting: Four inertial code switches SW5-SW8 are used to set the driver step subdivision number. There are 16 micro-step components. When user settings are subdivided step by step, the driver should stop running first. Specific micro-step subdivision settings, please drive layout instructions.
2) Output Current Setting: Three SW1-swa code-lifting switches are used to set the driving quantity of the wheel-out telephone, and its output current is 8 files. For specific output current settings, please refer to the driver base layout instructions.
3) Automatic half-stream function: Users can set the driver's automatic half-stream function through SN4. OFF indicates that the static electro-hydraulic current is set at half of the dynamic current, and ON indicates that the static current is the same as the dynamic current. SW4 should be set as oF in general use, so that the heat of motor and driver can be reduced and the chapterability can be improved. After the stop of the pulse train, the current of about 0.4 is automatically reduced to about half (60% of the actual value), and the fever is theoretically reduced by 36%.
4) Signal interface: PUL+and PUL-are the positive and negative end of control pulse signal DIR+and DIR-are the positive end and negative end of direction signal ENA+and ENA-are the positive end and negative end of enabling signal.
5) Motor Interface: U,V.W corresponds to the U,V,W of the motor's turn-in line, and two of the three consecutive sets of lines can be adjusted arbitrarily to change the direction of the motor.
6) Power supply interface: DC power supply is adopted, the working voltage range is recommended to be 24-80VDC, and the power supply is more than 300 W.
7) Indicator light: The driver has two red and green indicators. Among them, the green light is the power indicator. When the driving quantity is on, the rear light will turn on the red light. When the over-voltage and over-flow barrier indicator light appears, the fault light will always turn on. After the trouble is cleared, the red light goes out. When the driver is thin, only re-energizing and re-enabling can remove the wire barrier.
8) Installation instructions: The size of the driver is 140x97x48mm, and the distance between the mounting holes is 133 mm. It is recommended that the driver be installed vertically as well as pictorially. When installed, it should be attached to the cabinet to facilitate scattering.
Parameter setting
The 3MDB83ES driving suit uses a human dial switch to set subdivision accuracy, dynamic current and half-current dangerous current.
