LC2054DA M542 Two-Phase Stepper Motor Driver DC 24-50V Analog Current 4.2A for CNC Dispenser 42 57 Stepper Motor

LC2054DA M542 Two-Phase Stepper Motor Driver DC 24-50V Analog Current 4.2A for CNC Dispenser 42 57 Stepper Motor

Specifications:
- Drive voltage: DC 24-50V (DC 36V is better)
- Specific range: 2-123
- Pulse: single pulse
- Drive motor: 2 phase 42/57 stepper motor
- Drive current: 0.71A-3A (MAX.4.2A)
- Signal voltage: 5V; 12V/ 24V needs the current limitation resistor
- Alarm output: NO
- Standby half flow: Yes

Function:
- Working current setting: The driver output current is set by three dip switches SW1 - SW3,its output current has eight floors in all. About specific output current Settings, please refer to the drive panel.
- Automatic half flow function: Users can set drive to automatic half flow function through SW4.OFF shows the static current is set to be half of the dynamic current,ON shows the static current is the same as dynamic current .SW4 should be set to OFF in general use  in order to reduce the heating of the motor and driver , also to improve the reliability. The current will reduce by 50% automatically 0.3 seconds approximately after the pulse train stop (55% actual value), calorific value reduced by 65% in theory.
- Micro step subdivision setting: The driver micro step subdivision is set by four dip switches SW5 -SW8, there are 15 files of micro step subdivisions in all.When users are setting segmentation, the driver should be stopped
first.  About the setting of micro step subdivision , please refer to the drive panel.
- Indicator light: Drives have two red and green lights.One of the green light is power light,It will be abidingly on after the driver is electrified; the other red light is fault  indicating lamp, when being overvoltage and overcurrent problems, trouble light will be abidingly on. After the fault being cleared, the red light turns off. When a driver becomes disabled, only re-up electricity and reuse can clear the fault.
- Signal interface: PUL + and PUL - are the plus side and  minus side of  signal controlling DIR + and DIR - are the plus side and  minus side of direction signal.ENA + and ENA -are the plus side and  minus side of enable signal.
- Motor interface: A + and A - connectting the plus and minus side of step motor A phase  winding.   B + B and B -connectting the plus and minus side of step motor B phase winding.   When A, B two phase winding exchanges, can make the motor to reverse direction.
- Power port: Using the dc power to supply,  operating voltage range is suggested to be 24V-50VDC. Power is greater than 100 w.
- Installation instructions: The  boundary  dimension of drive is : 117 * 78 * 34 mm. The Installation pitch-row  is 111 mm. Either horizontal or vertical installation can work.(vertical installation is recommended).When installation, should make it close to the metal cabinet to facilitate heat dissipation.

Parameter setting:    
LC2054DA driver uses eight dip switches to set the segmentation accuracy, dynamic current and half/full flow, detailed description as below:    Working current setting: SW1, SW2, SW3; Half/ full flow mode setting: SW4; Subdivide microstep setting: SW5, SW6, SW7, SW8.
