What Is the 5/24V DIP Switch on Top of the Driver? Does It Relate to the Input Power?
This DIP switch primarily controls the receiving voltage range of the PUL/DIR signal ports and has no relation to the driver's power supply input.
In previous versions, the signal ports (PUL/DIR) of the driver were always compatible with 5–24V and were not affected by any DIP switch. However, because this wide compatibility range made it difficult for the driver to recognize low-voltage signals (e.g., 3.3V), this posed a challenge for compatibility with small controllers. Therefore, our newer version drivers include a signal voltage setting via a DIP switch. When set to the 5V position, the driver can recognize 3.3V signal voltage more stably.
The DIP switch is set to the 24V position by default.
Why default to 24V instead of 5V? Considering the widespread use of PLCs, if the switch were set to 5V and a 24V signal were accidentally applied, the PUL/DIR ports could easily be damaged due to
overvoltage. When set to 24V, even if a 5V pulse signal is applied, it will only result in an undervoltage condition (signal too low) without causing damage.
- When the switch is in the 24V position:
The driver's PUL/DIR ports only accept 24V pulse signals from controllers (e.g., PLCs). If the controller is an Arduino-like microcontroller board (typically 3.3–5V), the pulse signal voltage will be too low for the driver to recognize, and the motor will not run.
- When the switch is in the 5V position:
The PUL/DIR ports only accept 5V pulse signals from controllers (e.g., an Arduino). If a signal higher than 5V is applied—especially a 24V pulse signal from a PLC—it will not be recognized by the driver.
Therefore, please select the appropriate DIP switch position based on the pulse signal voltage from your controller. Otherwise, you may encounter a situation where the product itself is intact, all wiring is correct, the driver shows no alarm, but the motor simply does not run.
Finally, please note that other signal ports on the driver—such as the ENA input and ALM output—remain 5–24V compatible and are not affected by this DIP switch.
