Integrated Stepper Motor Controller and Driver for Nema17/Nema23 – Standalone Operation, No Coding Required
Need to control a stepper motor without the hassle of writing code, using an Arduino, or relying on a PC? This integrated stepper motor controller and driver is the perfect solution. Simply configure your settings using the built-in potentiometer and buttons, start your motor, and you’re ready to go. This compact, all-in-one unit replaces two separate components, significantly reducing wiring complexity.
Note: This module controls a single axis. It is compatible with 2-phase stepper motors featuring 4, 5, 6, or 8 wires. It can operate as a standalone unit or be connected to external stepper drivers or a PLC.
Why choose this controller? (Key Advantages):
- Zero external dependencies — No need for Arduino, Raspberry Pi, or Python; configure everything directly on the module in under 5 minutes.
- 9 pre-configured working programmes — From simple rotation to complex sequences with automatic reversal, delays, and infinite loops, all without additional programming.
- HD LCD with memory — Displays RPM, cycles, and delays in real-time; your configuration is saved even after power is disconnected.
- Smooth start and stop — Adjustable acceleration and deceleration (100 levels) to prevent mechanical shock and extend the life of your gears.
- 4A output current — Powerful enough to drive Nema 23 motors under medium loads without needing an external driver.
- Microstepping up to 1/32 — Adaptable positioning precision for everything from rapid movements to ultra-fine adjustments.
- Reverse polarity protection — Built-in protection ensures the module isn’t damaged by incorrect wiring during installation.
- Wide operating temperature range — Designed to perform reliably between –20°C and +85°C, making it suitable for industrial warehouses, unheated workshops, or high-humidity environments.
Performance and Specifications
The logic controller and power driver are housed in a single 79 × 43 × 41 mm unit, eliminating the need for separate components and messy cabling. Speed is continuously adjustable between 0.1 and 999 RPM via the potentiometer or parameters F-03/F-05, while the number of pulses per cycle can be set up to 9,999,999. Parameter F-09 allows for precise calibration of pulses per rotation based on the step angle and chosen microstepping — for example, a 1.8° motor with 1/8 microstepping generates 1600 pulses/rotation, so you would set F-09 = 160.

Programming and Usage Instructions
Running Interface (Normal Mode):
- The first LCD line displays rotation speed in RPM; the second line displays the delay or cycle count (configurable via F-10).
- The CW button starts clockwise rotation; the CCW button starts counter-clockwise rotation.
- The RUN/STOP button starts or stops the motor (smooth or immediate stop, depending on F-11).
- The potentiometer adjusts speed in real-time for both directions.
Accessing the Parameter Menu (F-01 – F-13):
- Press and hold the potentiometer for more than 3 seconds to enter settings mode.
- Rotate the potentiometer to navigate between parameters F-01 → F-13; the selected parameter will flash on the screen.
- Press the potentiometer to select the parameter value and rotate to modify it.
- Press RUN/STOP to confirm the entered value.
- Press and hold the potentiometer for more than 3 seconds to save and exit the menu.

Working Modes P01 – P09 (F-01):
| Mode | Behaviour Description |
|---|---|
| P01 | Motor responds exclusively to the potentiometer: clockwise = CW, counter-clockwise = CCW. Buttons are inactive. |
| P02 | Rotation according to F-02/F-04 pulses; stop after each set; reset with potentiometer; loop according to F-06. |
| P03 | Alternating rotation and stop according to F-02/F-04 pulses. Stop the motor before changing direction. |
| P04 | Sequence: F-02 → stop F-07 → loop F-06 times (forward); F-04 → stop F-08 → loop (reverse). |
| P05 | Rotation F-02/F-04 → stop → return in opposite direction → loop F-06 times. |
| P06 | Full sequence: F-02 → stop F-07 → reverse F-04 → stop F-08 → loop F-06 times. |
| P07 | Rotation F-02/F-04 → stop → return to origin in opposite direction (no fixed cycle count). |
| P08 | Time-based rotation: F-07 → stop F-08 → loop F-06 times. |
| P09 | Full sequence: forward rotation F-02 → stop F-07 → reverse rotation F-04 → stop F-08 → loop F-06 times. |

Frequently Asked Questions
Is it compatible with Nema 17 and Nema 23 stepper motors?
Yes. It works with 2-phase stepper motors of the Nema 17 (42mm) and Nema 23 (57mm) type, regardless of whether they have 4, 5, 6, or 8 wires.
Do I need an Arduino or other microcontroller?
No. The module operates completely autonomously — you configure everything using the potentiometer and buttons. It can optionally be connected to a PLC or external driver, but this is not required.
Can I control multiple axes simultaneously with one module?
No, it controls a single axis. For multiple axes, you will need one module for each motor.
How do I calculate the correct value for F-09?
Formula: (360 ÷ step_angle) × microstepping ÷ 10. Example: 1.8° motor with 1/8 microstepping → (360 ÷ 1.8) × 8 ÷ 10 = 160. Set F-09 = 160.
