Directly cut into the topic: 8 aspects of stepper motor driver application 1. Set up automatic oiling parameters (Set too small a few, such as 5 seconds to add a oil), observe whether automatic refueling is correct, if correct, will be automatically added parameter is set to the parameters of the actual needs. 2. Set up the fine fraction of stepper motor drives, usually fine fraction is higher, the higher the control resolution. But affect the largest fine score high feed rate. In general, for the mould machine users may consider pulse equivalent to zero. 001mm/P(The largest feed rate of 9600 mm/min)Or 0. 0005mm/P(The largest feed rate of 4800 mm/min); For user accuracy is not high, larger pulse equivalent can be set up, such as 0. 002mm/P(The largest feed rate of 19200 mm/min)Or 0. 005mm/P(The largest feed rate of 48000 mm/min)。 For two phase stepper motor, pulse equivalent calculation method is as follows: pulse equivalent = screw pitch & divide; Fine fraction & divide; 200. 3. Single spindle acceleration: a term used to describe a single feed shaft deceleration ability, square unit is mm/SEC. This index is determined by the physical properties of machine tool, such as the quality of the moving parts, the feed motor torque and drag, cutting load, etc. This value, the greater the cost in the process of movement in the process of acceleration and deceleration time is smaller, the higher the efficiency. Normally, for stepper motor, the value is between 100 ~ 500, for step motor system, can be set up between 400 ~ 1200. In the process of setting, began to set up a little bit small, running for a period of time, repeat a variety of typical movement, observe, if there is no abnormal situation, and then gradually increase. If it is found that abnormal situation, the lower the value, and keep insurance allowance of 50% ~ 100%. 4. Takeoff speed: this parameter corresponding to jump frequency of stepping motor. The so-called jump frequency is stepping motor without speed, can directly start the work of the highest frequency. Reasonable to select the parameters can improve the machining efficiency, and can avoid bad step motor movement characteristics of low speed; But if the parameters selection, can cause nausea, so be sure to leave allowance. In the motor factory parameters, generally contain jump frequency parameters. But after the assembled machine tool, this value may change, generally to drop, especially when doing load movement. So, the setting parameters preferably in reference motor factory, then the actual measurement. 5. Curve acceleration: a term used to describe multiple feed axis linkage deceleration capability, square unit is mm/SEC. It determines the highest speed at which the machine was in a circular motion. This value, the greater the the maximum allowable speed of machine tool was in a circular motion. Usually, for step motor system of machine tool, the value is between 400 ~ 1000, the stepping motor system, can be set between 1000 ~ 5000. If it is a heavy duty machine tool, the value is smaller. In the process of setting, began to set up a little bit small, running for a period of time, repeat a variety of typical linkage movement, observe, if there is no abnormal situation, and then gradually increase. If it is found that abnormal situation, the lower the value, and keep insurance allowance of 50% ~ 100%. Usually consider the stepper motor driver ability, friction of mechanical assembly, mechanical parts of bear ability, can modify the maximum speed of the shaft in the vendor parameters, the actual machine tool users use the three axis of maximum speed limits. 6. To determine whether the pulse. You can use an intuitive method: use a sharp knife on the workpiece blank point a point, the point is set to work at the origin, push up the Z axis, and then set the Z axis coordinates to 0; Machine movement again and again, such as air knife runs a typical processing program (Best included three-axis linkage), can pause or stop in processing, and then back to the origin of workpiece, slow down the Z axis, it fits the point and the point of the blank. If there is any deviation, please check the stepper motor drive, receive the pulse signal types, check whether terminal board and indirect drive line is wrong. If also appear stuffy car or throw step, according to the step 10, 11, 12 adjusting parameters such as acceleration. 7. Check the electronic gear and pulse equivalent value matches. Can do it on a shaft in machine tool, work in software set point coordinates to zero, with direct input command, inching or handwheel works make the shaft fixed distance, measured with vernier caliper distance with the software coordinates shows the actual distance is attached. 8. According to the three axis zero sensor installation location, back to the origin of the mechanical parameters of parameter setting the manufacturer. When set up properly, it can be run & other; Operation & throughout; From the menu & other; Back to the mechanical origin & throughout; 。 Uniaxial back first, if the movement in the right direction to continue, or need to stop, reset the parameters of mechanical origin back direction set manufacturers, until all axis can be back to the mechanical origin. Above is should pay attention to in the application of stepping motor drive eight link, do you know how many? the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
