产品名称:

LCDA808H 2 Phase Nema34 stepper digital servo driver

Product Name: LCDA808H 2 Phase Nema34 stepper digital servo driver
上市日期:2017-03-20
产品型号:

LCDA808H using the latest dedicated motor control DSP chip and vector closed-loop control technology, completely overcome the open-loop stepper motor lost step problems, while significantly enhance the motor high-speed performance, reduce motor heating and reduce motor vibration, improve machine processing speed and accuracy, Machine energy consumption. This drive is suitable for motor mounting size is fully compatible with 86 series stepper motor to facilitate the traditional step-by-step drive program upgrade, significantly reduce costs.

Name

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
