1. Electrical parameters:

1. High definition control signal

PLS+: step pulse signal positive terminal or step positive pulse signal input positive terminal

PLS-: step pulse signal input negative terminal or step positive pulse signal input negative terminal

DIR+: Step direction signal positive terminal or reverse step pulse signal positive terminal

DIR-: step direction signal input negative terminal or reverse step pulse signal input negative terminal

ENA+: Offline enable signal reset input positive terminal

ENA-: Offline enable negative terminal input reset signal.

When the offline enable signal is valid, the drive fault is reset, any valid pulse is prohibited, the output power of the drive element is turned off, and the motor has no holding torque.

2.Control signal connection

The host computer control signal can have a high level performance or a low level. When effective high, connect the negative ends of all control signals together as the signal GROUND, when LOW, connect the positive ends of all control signals together as the common signal end. The circuit diagram interface is as follows:

Wire drive:

A complete stepper motor control system should include stepper drives, DC power supplies and controllers (pulse sources).

The following is a general system wiring diagram:

3. Set the current phase

In order to drive stepper motors with different torques, users can set the phase current. (effective value) of the drive amp through the DIP switches SW1, SW2, and SW3 on the drive panel, the corresponding output current of each switch position, and the pattern can be different. The corresponding output current value is different. See the table for details.

4. Interface:

1.V, GND: Connect the Driver Power Supply.

+V: DC positive, voltage DC 16~50V High current is 4.2A.

GND: Negative DC level

2. A + AB + B-: Connect the 2-Phase HYBRID Stepping Motor.

The connection between the driver and the 2-phase hybrid stepping motor uses four wires. The motor winding has a parallel and connection method, and the parallel connection method has good speed performance, but the driver current is large (1.73 times the motor winding current).

In series connection driver current is equal to motor winding current.

5. Installation:

There should be a space of 20mm around and should not be placed next to other heating equipment. Avoid Dust, Oil Mist, Excessive Corrosive Gas, Humidity and Strong Vibration.

Troubleshooting:
1. Status indicator light
RUN: Green, ON during normal use.
ERR: Red light, when a fault occurs, the circuit between the motor steps, G voltage and under voltage protection.

2. Failure and Troubleshooting

 

1. LED does not light up reason: (wrong power connection/low voltage)
Solution: 1 check the power cord 2 increase the power supply voltage

 

2. Motor does not rotate and no holding torque (reason: motor incorrect connection/offline enable reset signal available)
Solution: Incorrect reset/correct motor connection.

3. The motor does not rotate, but has a holding torque (reason: no input pulse signal).
Solution: Adjust the pulse and signal level.

 

4. Wrong direction of motor (reason: wrong power line sequence/wrong signal direction)
Solution: Interchange two wires to connect and change direction setting.

 

5. Motor torque is too small (reasons: the phase current setting is too small, the acceleration is fast, the motor is blocked, the driver and the motor do not match).

 

Solution: Correctly set the phase current, reduce the acceleration value, eliminate mechanical faults, and replace the appropriate driver.
