LCDA86H adopts the latest special motor control DSP chip and vector closed loop control technology, completely solves step missing issues for open loop stepper motor, completely solves step missing issues for open loop stepper motor, obviously improves motor performance at high speed, reduces heat generation
and vibration of motor, increases processing speed and precision of machine, decreases power consumption, applies to 2 phase Nema34 closed loop motors, has both stepper and servo advantages, is 50% cheaper than servo systems in market and an optimal upgrading stepper program for clients.

LCDA86H Features

● Voltage input range: DC30V~100V / AC20V~70V
● Max peak current: 6A
● Subdivision range: Default 4000/rev, any subdivision (200~51200) can be
● set through debugging panel.
● Pulse limit frequency: 200KHZ
● Signal input: Pulse, direction and enable signals
● Output signal: In-place signal and failure output signal, full motor encoder
● feedback: AB differential input.
● Over-voltage, over-current, tracking error and out of error protection functions.
● Closed loop vector control, assure high-speed and big-torque output and no step missing of motor.

(3) Control Signal Port

Name Description
PUL+ Pulse input signal: the rising edge of the pulse is valid; in order to respond to the pulse signal reliably, the pulse width should be greater than 2.5μs. Compatible with 5V-24V signals, no series resis tance  is  required.
DIR+ Direction input signal: switch the motor direction by high/low level signal, the direction signal should be established at least Sus before the pulse signal. Compatible with 5V-24V signals, no series resistance is required.
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 terminal can be left floating. Compatible with 5V-24V signals, no series resistance is required.
Pend+ Positive  Terminal  of  Positioning  Finish  Signal
