Instructions for Using TB6560AHQ

1. Power Supply Connection:

   • Connect the VCC pin to the main power supply (12V to 45V).
   • Connect the VCC-IO pin to the logic power supply (4.5V to 5.5V).

2. Motor Connection:

   • Connect the motor phases to the corresponding output pins (A1, A2, B1, B2, C1, C2).
   • Ensure the motor is rated for the maximum output current (3.5A per phase).

3. Control Signal Configuration:

   • Connect the step pulse signal to the STEP pin.
   • Connect the direction signal to the DIR pin.
   • Set the microstep resolution using the MS1, MS2, and MS3 pins.

4. Enable and Standby:

   • Set the ENB pin to LOW to enable the driver.
   • Set the ENB pin to HIGH to put the driver into standby mode, reducing power consumption.

5. Protection Features:

   • The driver includes overcurrent protection (OCP), thermal shutdown (TSD), and under-voltage lockout (UVLO) to protect the device from damage.

6. Thermal Management:

   • Ensure adequate heat dissipation by mounting the driver on a heatsink or using a cooling fan, especially when operating at high power levels.

7. Microstep Operation:

   • Use the MS1, MS2, and MS3 pins to select the desired microstep resolution (1/2, 1/4, 1/8, 1/16).

8. Frequency Considerations:

   • The maximum input pulse frequency is 200kHz. Ensure the step pulse signal does not exceed this limit to avoid performance issues.

9. Initial Setup:

   • Before powering on the driver, verify all connections and settings to ensure proper operation and prevent damage to the motor or driver.

10. Testing:

    • After setup, test the motor with a simple step sequence to confirm proper operation. Adjust the microstep resolution and other parameters as needed for your application.
