2 Phase closed loop servo stepper driver series

LCDA86 2 Phase closed-loop driver

Features:


1. Voltage input range:  VDC: 30 ~ 100V
2. Maximum peak current: 6A
3. Subdivision range: the default 4000 / rev, through the debug board can be set to any subdivision (200-51200)
4. Pulse limit frequency: 200KHZ
5. Signal input: pulse, direction and enable signal
6. Output signal: in place signal and fault output signal
7. Motor encoder feedback: AB differential input
8. Closed-loop vector control to ensure that the motor high-speed large torque output, while ensuring that the motor does not lose step
9. With over-voltage, over-current, tracking error tolerance and other protection functions

    Name
    Explanation
    PUL
    Pulse input signal: pulse rising edge effective; in order to reliably respond to the pulse signal, the pulse width should be greater than 2.5μs. Such as the use of +12 V or +24 V series resistance required 3K.
    PUL
    DIR
    Directional input signal: The direction of the motor is switched by the high / low level signal, which should be established at least 5μs before the pulse signal. Such as the use of +12 V or +24 V series resistance required 3K.
    DIR
    ENA
    Enable control signal, this input signal is used to enable or disable the driver output. When this function is not needed, the enable signal can be left floating. Such as the use of +12 V or +24 V series resistance required 3K.
