LCDA86 2 Phase Nema24 closed-loop driver

Product Name: LCDA86 2 Phase Nema24 closed-loop driver
上市日期:2017-05-19
产品型号:

LCDA86 uses the latest dedicated motor control DSP chip and vector closed-loop control technology, completely overcome the open-loop stepper motor stepped the problem, 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 takes into account the dual advantages of stepping and servo, and its price than the market on the servo system significantly reduced by 50%, is the best choice for customers to upgrade the program.

3) Control signal port:

 

 

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.
