Electrical network stepper motor drive device is very important, is directly related to the motor function, overall quality and life of the motor and so on all has a huge impact. So ready to cover part of the design, make guarantee on its quality and effect is very important. The design of the drive, because fine score, the higher the control resolution, so some people would say its fine points set, the higher the better. So whether the stepper motor drives fine points set, the higher the better? In fact is not the case, fine while it's true that the higher the score, the control resolution is higher, is advantageous to the motor to realize high precision control, and improve the precision of Angle. But if the fine fraction set too high, also will be some deficiencies, not affect the largest feed speed, it will run of motor and adverse impact on performance. So the fine fraction of stepper motor drives is not set, the higher the better, in general, for mould machine users may consider pulse equivalent to zero. 001 mm/P or 0. 0005 mm/P, the two set maximum feed speed cases for 9600 mm/min)And 4800 mm/min. Such fine fraction sets is better status, both control resolution and largest feed speed can be a good guarantee. If is the user accuracy is not high, the stepper motor drives, setting of fine fraction, pulse equivalent can set a few bigger. For instance is set to 0. 002 mm/P or 0. 005 mm/P, this time the largest feed rate is respectively 19200 mm/min)And 48000 mm/m, which is very good, can well meet the use requirements. Another set of stepping motor drives the fine fraction everyone needs to be clear: for two phase stepper motor, pulse equivalent calculation method is commonly: pulse equivalent = screw pitch & divide; Fine fraction & divide; 200, in the specific setting, pay attention to the concrete calculation according to the aspects.
