Specification parameters

Working voltage: The working voltage is about 280V

Working mode: Supports multiple working modes, including open-loop mode, voltage mode, current mode (torque mode), IR compensation mode, Hall speed mode, encoder speed mode, speedometer mode, analog position loop mode (ANP mode), etc. (Note that not all modes are applicable to all models of drivers).

Core functions

There are various motor control modes: in open-loop mode, the output load rate of the driver is controlled by inputting command voltage, which is commonly used in brushless motor drivers and performs similarly to the voltage mode of brushed motor drivers; In voltage mode, the input command voltage directly controls the output voltage of the driver, which is suitable for brushed motor drivers and similar to the open-loop mode of brushless motor drivers; In current mode (torque mode), the input command voltage controls the output current (torque) of the driver, and the driver automatically adjusts the load rate to maintain the command current value. This is commonly found in drivers with speed or position loop operation capabilities.

Speed closed-loop control: With the help of hall sensors, encoder pulses, or analog speedometers on the motor, a speed closed-loop can be formed. The Hall speed mode utilizes Hall sensor frequency to construct a speed loop, but due to its low resolution, it is not suitable for low-speed motion scenes; The encoder speed mode relies on the encoder pulse frequency, and due to the high-resolution characteristics of the encoder, it can achieve smooth motion control at various speeds; The speedometer mode utilizes an analog speedometer to achieve more precise speed control, but is susceptible to interference at low speeds.

Position control: In ANP mode, the input command voltage is used to control the rotational position of the motor. This mode is essentially a special speed mode that provides position feedback in the simulation device. The motor speed is proportional to the position error and has the advantages of fast response and small steady-state error
