The motor winding current is limited by means of a 35KHZ-chopper scheme. One phase is always on, but never more than one.

Wavedrive Pulse the J low for at least 5usec, then with J High, pulse J low for at least 5usec then bring J low. What is the power source for the motors? The full step mode provides the maximum low speed torque because two windings are always energized. Here is a good information on Stepper Motor Basic you might want to read. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

A logic high on this input allows current to be applied to the motor windings, A logic low disables the output driver. You also didn’t specify what is the Vref applied in pin 15 of L It is designed to accept step pulses at up to 25, per second.


The output driver is capable of driving up to 2Amp into each phase of a two-phase bipolar step motor. The potentiometer R6 is for varying the winding currents. A useful of this design is the “idle” current reduction mode. If you need help to build or have hard time to find the parts for this project, please feel free to email us at support wzmicro.

It must be high for at least 1usec between pulses, and may not repeat more than 25, times per second. Click the image to enlarge Introduction This Stepper motor controller uses the L and LN driver combination; it can be used as stand alone or controlled by microcontroller.

L Stepper motor controller data sheet. When brought low, this line select the full step or wavedrive modes. For additional stepper motor drivers see the Links below For additional information and resources on stepper motor drivers see the Links below There is nothing wrong with the schematic, after all it is the reference design of the chip manufacturer. What is the current limit you have set for each coil? This Stepper motor controller uses the L and LN driver combination; it can be used as stand alone or controlled by microcontroller.


Increments the motor step counts in the selected direction by one step or haft step. I have hooked up the step and direction pin number 4 and 5 respectively on Arduino.

The step angle per step pulse is the same as the full step mode, but less low-speed 2l98 available. J3 Pin Functions Step pulse J It is not recommended to run the stepping motions at this low current. Depending on the current you want to use for the motor coils the supply current may or may not be enough.

Send mail to info wzmicro. The wavedrive mode is a variation on the full step mode which exhibits the following phase pattern: Sign up using Facebook.

The minimum Step o298 width is 1usec, and can remain low indefinitely if needed. A high on this pin indicates the controller is in the “Home” state. The input can select between 3 operation modes.
