5065 stepper motor controller TB65560 fritzing

It is actually essential for correct operation that the current limit is triggered, so it needs to be set correctly for the motor to step reliably, it isn't just about setting it as high as possible to drive the motor to it's limits. Try to read up on how the stepper motors and their drivers actually work - they are driven by approximately sinusoidal currents that are at different phases in each motor winding. For example, page 11 onwards in the TB6560 datasheet clearly shows that 100% of the limit current is applied to each phase regardless of excitation mode. I would strongly recommend that you look at the datasheets for the motor and the stepper driver that you intend to use, as they fully explain everything you are asking.

See Table 2 in the DRV8825 datasheet to understand this further. DRV8825) you can set the current limit to 1.4x the single phase current, because when in full-step mode only, the maximum current through each phase is only 0.71x the current limit. Step the motor with a constant speed as set by setSpeed():Ī simple answer to this is that the number of phases does not affect the current limit, because at some point in the stepping sequence 100% of the current will be directed to one phase with 0% (or -100%) directed to the other.įor some stepper drivers (e.g. Set the maximum speed and acceleration: Create a new instance of the AccelStepper class:ĪccelStepper stepper = AccelStepper(motorInterfaceType, stepPin, dirPin) Motor interface type must be set to 1 when using a driver: Define stepper motor connections and motor interface type. * Example sketch to control a stepper motor with TB6560 stepper motor driver, AccelStepper library and Arduino: acceleration and deceleration.

I can works from full to 1/32 revolution. Whit this code, I don't know if it is interesting to change the step mode. I set 1.9 because the datasheet recommended a driver of 2Amp. I set the current limit of the TB6560 to 1.9 amp and I work in full-step mode. For this, I use the AccelStepper Library test that you can see below.īut the motor of my pump is very hot.

My project needs that the pump works 24/24 7/7 without blocking function (I need to control others pump and sensors). The seller assured me that it can work continuously). I drive a peristaltic pump with a stepper motor at continuous speed (Yeah, I know it's better with Brushless but It's really difficult to find brushless peristaltic pump.
