100 dating 2208
Compatible with existing 3D printer electronics, eliminating the expensive costs of redesign.With a standard step/dir interface, it is easy to use.It can replace the original TMC2100, lower heat, especially for 3D printing market. The TMC2208 outputs continuous motor current up to 1.4A and peak current up to 2A.The best way to set the motor current is by measuring the voltage on the Vref pin (0…2.5V) and adjusting the voltage with the potentiometer.The maximum settable motor current is 1.77A RMS (0.11Ohm sense resistors), but the Silent Step Sticks can only be used up to 1.2A RMS.Tip: Use images with a small size and optimize their download with gzip.
Make sure your title is explicit and contains your most important keywords. It allow you to influence how your web pages are described and displayed in search results.Therefore, the reference voltage of the driver module should not exceed 1V.At the same time, the driver module must be dissipated, otherwise it will affect the life of the driver module.Irms = (Vref * 1.77A) / 2.5V = Vref * 0.71 Vref = (Irms * 2.5V) / 1.77A = Irms * 1.41 = Imax Vref - 1. If you enable spread Cycle then TOFF cannot be 0 (null).Vref measures Gnd and the voltage at the middle of the potentiometer. Do not connect the motor when measuring the voltage, otherwise it is easy to burn the driver. Power should be connected when measuring voltage, do not just connect USB power supply. You can use every RS232 serial adapter with 0-5V logic levels (e.g.
