Product Description

LICHUAN® is 2-phase Stepper Motor Driver With Closed Loop Technology manufacturer and supplier in China.

LCDA257E/LCDA257F adopts the latest special motor control DSP chip and servo control technologies, 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 Nema23 closed loop stepper motors, is convenient for upgrading traditional stepper driver solutions and largely reduces cost.

LCDA257F Features

1.Voltage input range: DC: 20V ~ 50V (recommended 36V or more)
2. Maximum peak current: 6A
3. Subdivision range: 400 ~ 51200ppr
4. Pulse form: pulse + direction, CW / CCW
5. Impulse response frequency: 0 ~ 200kHz
6. Logic input current: 10 ~ 20mA
7. Power-on parameter auto-tuning function
8. Closed-loop vector control to ensure that the motor high-speed high-torque output, while ensuring that the motor does not lose step
9. With over-voltage, over-current, tracking error tolerance and other protection functions
10.More details Pls check driver manual on “download” catalog.

(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. 5V-24V signal compatible, A series resistor is not required.
DIR+ Direction input signal: switch the motor direction by high/low level signal, the direction signal should be established at least Sμs before the pulse signal. 5V-24V signal compatible,No series resistor 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.
ALM+ Positive Terminal of Alarm Output
ALM- Negative Terminal of Alarm Output
