Features

Advanced Micro – stepping Technology

The micro – stepping technology in the BLS2020 P160/1 is a key feature. By providing a high – resolution micro – stepping option, it enables smooth and precise movement of the step motor. This leads to reduced vibration and noise, which is particularly important in applications where quiet operation is essential, such as in medical equipment or precision manufacturing processes. The ability to adjust the micro – stepping resolution also offers greater flexibility in tailoring the motor’s performance to the specific demands of the application.

Built – in Protection Mechanisms

The driver is equipped with comprehensive protection features, including over – current, over – voltage, and over – temperature protection. In the event of an over – current situation, the driver will automatically shut down to prevent damage to the motor and itself. Similarly, if the input voltage exceeds the specified range or the temperature inside the driver becomes too high, the protection circuits will activate to safeguard the device. These protection mechanisms not only enhance the reliability of the driver but also contribute to the overall safety of the motion control system.

Easy Integration

It is designed for seamless integration into existing automation systems. The step driver is compatible with standard control signals, such as pulse + direction or CW / CCW signals, which are commonly used in motion control applications. This compatibility allows for a smooth connection with programmable logic controllers (PLCs), motion controllers, or other control devices. Additionally, if it has a communication interface (such as RS – 485 or CANopen), it can be easily networked with other components in a distributed control system, enabling remote monitoring and control.

Function

The primary function of the BLS2020 P160/1 step driver is to receive digital control signals from a controller (such as a PLC or a motion controller) and convert them into electrical signals to drive a step motor. When it receives a pulse signal from the controller, it energizes the appropriate windings of the step motor in a precise sequence to make the motor rotate by a specific angle. The direction of rotation is determined by the direction signal received.

The micro – stepping function of the driver further refines this process. Instead of simply stepping the motor in discrete full – step increments, it divides each full step into multiple micro – steps. For instance, if the micro – stepping resolution is set to 128 micro – steps per full step, the motor will move in much smaller, more precise increments. This results in smoother motion, reduced vibration, and improved accuracy in positioning the motor shaft. The built – in protection circuits continuously monitor the operating conditions of the driver, such as current, voltage, and temperature. If any of these parameters exceed the safe limits, the protection circuits will immediately take action to protect the driver and the connected motor.

Use

In practical applications, the initial step is to choose a suitable step motor that is compatible with the BLS2020 P160/1 step driver in terms of voltage, current, and torque requirements. The driver is then mounted in an appropriate location, taking into account factors such as heat dissipation and accessibility for maintenance. The input power supply, within the specified voltage range, is connected to the driver. Next, the control signals from the controller (pulse + direction or CW / CCW) are wired to the driver’s input terminals.

Before operation, the micro – stepping resolution and other parameters (such as current limit) may need to be adjusted according to the requirements of the application. This can usually be done through dip switches or software configuration, depending on the model. Once configured, the driver is ready to receive control signals from the controller. When the controller sends a series of pulses and the appropriate direction signal, the driver will drive the step motor to move in the desired direction with the specified precision. Regular monitoring of the driver’s operating conditions, such as temperature and current, is recommended to ensure reliable operation and to detect any potential issues at an early stage.
