3 Phase closed loop servo stepper driver series

LCDA2260E 3 phase Digital display closed loop driver

Features:


1. Voltage input range: 150 ~ 230VAC
2. Quiescent current and dynamic current can be set at 0 ~ 6A
3. Closed-loop vector control to ensure that the motor high-speed high-torque output, while ensuring the motor does not lose step
4. Built-in sub-sub-low-speed low-level operation can also be very smooth
5. Parameter automatic setting function
6. Current dynamic control greatly reduces the motor heat, ultra-low vibration noise
7. External digital debugging panel for easy parameter setting and monitoring
8. Sub-adjustable range of 200 ~ 51200ppr, impulse response frequency up to 200KHZ
9. Serial communication function, current, subdivision can be adjusted, signal edge, alarm output logic and other functions adjustable
10. Closed-loop vector control to ensure that the motor high-speed high-torque output,

while ensuring that the motor is not lost step  with over-voltage, over-current, tracking error tolerance

    Explanation

    PUL

    Pulse input signal: pulse effective edge adjustable, the default pulse rising edge is valid; in order to reliably respond to the pulse signal, the pulse width should be greater than 1.2μs. Such as the use of +12 V or +24 V when the need to string 3K resistance

    PUL

    DIR

    Direction input signal: high / low level signal, in order to ensure reliable reversing of the motor, the direction of the signal should be preceded by pulse signal at least 5μs to establish, such as the use of +12 V or +24 V string 3K resistor.

    DIR

    ENA

    Enable control signal: This input signal is used to enable or disable. When ENA +, ENA- have input, the drive will cut off the motor phase to make the motor in a free state. When this function is not required, the terminal can be left floating.
    Such as the use of +12 V or +24 V when the need to string 3K resistance
