Pin Configuration

Dual Shaft NEMA 34 CNC Stepper Motor 34HS46-5004D (8.5NM-5A) Pinout Explanation
The Dual Shaft NEMA 34 CNC Stepper Motor 34HS46-5004D (8.5NM-5A) has 8 pins, which are divided into two connectors: a 4-pin connector for power and a 4-pin connector for control signals. Here's a detailed explanation of each pin:
Power Connector (4 Pins)
1. VCC (Pin 1): This pin is the positive voltage supply for the motor. It should be connected to a power source with a voltage range of 24V to 48V DC.
2. GND (Pin 2): This pin is the ground connection for the motor. It should be connected to the negative terminal of the power source or the system ground.
3. VM (Pin 3): This pin is the motor voltage connection for the second winding. It should be connected to the positive voltage supply for the motor, similar to VCC (Pin 1).
4. GND (Pin 4): This pin is the ground connection for the second winding. It should be connected to the negative terminal of the power source or the system ground, similar to GND (Pin 2).
Control Connector (4 Pins)
1. DIR (Pin 5): This pin is the direction control signal for the motor. A high logic level (5V) on this pin sets the motor direction to clockwise, while a low logic level (0V) sets the motor direction to counterclockwise.
2. STEP (Pin 6): This pin is the step control signal for the motor. A pulse on this pin increments the motor position by one step. The frequency of the pulses determines the motor speed.
3. ENA (Pin 7): This pin is the enable control signal for the motor. A high logic level (5V) on this pin enables the motor, while a low logic level (0V) disables the motor.
4. NC (Pin 8): This pin is not connected (NC) and should be left unconnected.
Connection Structure
To connect the Dual Shaft NEMA 34 CNC Stepper Motor 34HS46-5004D (8.5NM-5A), follow these steps:
1. Connect the power supply to the motor:
VCC (Pin 1) to the positive terminal of the power source (24V to 48V DC)
GND (Pin 2) to the negative terminal of the power source or system ground
VM (Pin 3) to the positive terminal of the power source (24V to 48V DC)
GND (Pin 4) to the negative terminal of the power source or system ground
2. Connect the control signals to the motor driver or controller:
DIR (Pin 5) to the direction control output of the motor driver or controller
STEP (Pin 6) to the step control output of the motor driver or controller
ENA (Pin 7) to the enable control output of the motor driver or controller
NC (Pin 8) should be left unconnected
3. Ensure that the motor driver or controller is configured to match the motor's specifications, including the voltage, current, and step resolution.
Important Notes
The motor driver or controller should be capable of handling the motor's rated current (5A) and voltage (24V to 48V DC).
The power supply should be able to provide the required current and voltage for the motor.
The motor should be properly cooled to prevent overheating, especially in high-torque applications.
The motor's step resolution and speed should be configured according to the specific application requirements.

Code Examples

### Example 1: Arduino Uno - Simple Stepping

This example demonstrates how to control the stepper motor using an Arduino Uno board. The code uses the `Stepper` library to create a stepper object, which is then used to step the motor.

```cpp
#include <Stepper.h>

const int stepsPerRevolution = 200;  // Change this to your motor's step count
Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11); // Initialize stepper on pins 8-11

void setup() {
  // Set the motor speed to 50 RPM
  myStepper.setSpeed(50);
}

void loop() {
  // Step the motor 100 steps forward
  myStepper.step(100);
  delay(1000);

// Step the motor 100 steps backward
  myStepper.step(-100);
  delay(1000);
}
```

### Example 2: Raspberry Pi - Python - Stepping with Acceleration

This example demonstrates how to control the stepper motor using a Raspberry Pi and Python. The code uses the `RPi.GPIO` library to control the motor's phases and implements a simple acceleration profile to smoothly accelerate and decelerate the motor.

```python
import RPi.GPIO as GPIO
import time

# Set up GPIO pins for motor control
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)  # A+
GPIO.setup(23, GPIO.OUT)  # A-
GPIO.setup(24, GPIO.OUT)  # B+
GPIO.setup(25, GPIO.OUT)  # B-

# Set up motor parameters
stepsPerRevolution = 200
accelerationSteps = 100
decelerationSteps = 100

def step_motor(direction):
  if direction == 1:  # Clockwise
    GPIO.output(17, GPIO.HIGH)
    GPIO.output(23, GPIO.LOW)
    GPIO.output(24, GPIO.HIGH)
    GPIO.output(25, GPIO.LOW)
  else:  # Counter-clockwise
    GPIO.output(17, GPIO.LOW)
    GPIO.output(23, GPIO.HIGH)
    GPIO.output(24, GPIO.LOW)
    GPIO.output(25, GPIO.HIGH)

while True:
  # Accelerate to 500 steps/second
  for i in range(accelerationSteps):
    step_motor(1)
    time.sleep(0.001)

# Cruise at 500 steps/second
  for i in range(500):
    step_motor(1)
    time.sleep(0.001)

# Decelerate to 0 steps/second
  for i in range(decelerationSteps):
    step_motor(1)
    time.sleep(0.001)

# Repeat in the opposite direction
  for i in range(accelerationSteps):
    step_motor(-1)
    time.sleep(0.001)

for i in range(500):
    step_motor(-1)
    time.sleep(0.001)

for i in range(decelerationSteps):
    step_motor(-1)
    time.sleep(0.001)
```
