Stepper motor driver specificaiton: 


Introduction:

M542-type sub-type of two-phase hybrid stepping motor driver, DC power supply for drive voltage 20V ~ 50V, current is less than 4.0A, 42 〜86mm diameter two-phase hybrid steppingmotor. This drive by AC servo drive current loop subdivision control, the motor torque ripple is small, low-speedm, smooth running, low vibration and noise. High speed, relatively high output torque, high precision positioning. Widely used in engraving machines, CNC machine tools, packaging machinery, transmission equipment and other devices that require a higher resolution.


Features:

1. Average current control, two-phase sinusoidal output current drive

2. DC 24 ~ 50V power supply

3. Opto-isolated input / output

4. Overvoltage, undervoltage, overcurrent, short circuit protection phase

5. Subdivision sixteen files and automatic half current function

6. Eight stalls set the output phase current

7. With offline capabilities

8. High speed start

9. High-speed torque

Control signal interface


Figure 1 is a wiring diagram drive


1. The control signal definitions

PLS+: Positive In put pulse signal

PLS-: Negative pulse signal in put

DIR+: Positive sign al input termi nal step di recti ons

DIR-: Negative signal in put step directions

ENA+: offline enabli ng the reset signal in put is terminal

ENA-: offline enabling the reset signal input negative terminal

Offline enable signal is active reset drive failure, and no effective pulse, the output power of the drive components is closed, no motor to maintain torque.


2. The control signals connections

PC active high control signal can also be active low. When active high, the control signal to the negative side of all connected together as a

signal, the low effective, all control signals are connected together as a signal common. Now and PNP open collector output, for example, in terface

circuit diagram is as follows:

Note: 

VCC is 5V, R shorted;

VCC is 12V, R is 1K, more than 1/8W resistance;

VCC is 24V, R for the 2K, more than 1/8W resistor;

R must be connected to the controller terminals.


Function selection(With the drive to achieve on the panel DIP switch,see Figure 1)


1. set the number of motor steps per revolution Drives the motor, respectively, the number of steps per revolution is

set to 200,400,500,800,1000,1250,1600,2000,2500,3200,4000,5000,6400,8000,10000,12800 step. You can drive through the front panel DIP switch SW5, SW6, SW7, SW8 bit to set the drive number of steps (Table 1):


SW5 OFF ON OFF ON OFF ON OFF ON OFF ON OFF ON OFF ON OFF
SW6 ON OFF OFF ON ON OFF OFF ON ON OFF OFF ON ON OFF OFF
SW7 ON ON ON OFF OFF OFF OFF ON ON ON ON OFF OFF OFF OFF
SW8 ON ON ON ON ON ON ON OFF OFF OFF OFF OFF OFF OFF OFF
Pulse/rev 400 800 1600 3200 6400 12800 25600 1000 2000 4000 5000 8000 10000 20000 25000
Table 1


2. control mode

DIP switches SW4-bit control can be set into two:

Set to "OFF" when, as a semi-streaming capabilities.

Set to "ON" when, for no half-streami ng capabilities.


3. set the output phase current

The different torque to drive the stepper motor, the user can drive the panel DIP switch SW1, SW2, SW3 bit to set the drive's output phase current (RMS) per ampere, the switch position corresponds to the output current, different models drive output current corresponding to different values. Detailed in Table 2.

Output Current (A)
SW1 SW2 SW3 PEAK RMS
ON ON ON 1.00 0.71
OFF ON ON 1.46 1.04
ON OFF ON 1.91 1.36
OFF OFF ON 2.37 1.69
ON ON OFF 2.84 2.03
OFF ON OFF 3.31 2.36
ON OFF OFF 3.76 2.69
OFF OFF OFF 4.20 3.00 
Table 2


4. the semi-flow function

Semi-flow function is non-500ms after the step pulse, the driver output current automatically reduced to 70% of rated

output current, is used to prevent motor heat.


Power Interface

1. AC1, AC2, PE: connect the drive power

220VAC in put power supply voltage is the maximum current is 5 A. Power line cross-section > 1.5 square mm, as short

as possible. Driver side and AC2 AC1 termi nation power supply, while external to series with a 6A fuse. PE grou nd

terminal.


2. A + A-B + B-: to link the two-phase hybrid stepping motor

Drive and two-phase hybrid steppi ng motor connected by four-wire system, the motor win dings in parallel and series

connection, and connection method, high-speed performa nee, but the drive curre nt (the motor win ding curre nt 1.73

times), the series connection When the drive current is equal to the motor winding current.

Note: If the power supply without isolation transformer, the need to drive PE ground terminal and the motor reliable

grounding.


Installation

To have 20mm of space around, can not be placed next to other heating devices, to avoid dust, oil mist, corrosive gas,

humidity, vibration is too large and strong places.

Troubles and its shotting ways

1. the status lights indicate

RUN: green, normal work light.

ERR: red, light failure, the motor phase short circuit, overvoltage and undervoltage, drive over temperature (heat sink

temperature exceeds 75 degrees.)


2. Troubles

Failure Reason Solutions
LED off Pick the wrong power supply Check the power conn ection conn ection
Low supply voltage Improve the power supply voltage
Motor does not turn, and not to keep the torque Electrical connections not Correct motor connections
RESET signal to enable the effective offline The RESET is not valid
Motor does not turn, but maintain the torque No pulse signal input Adjust the pulse width and signal level
The direction of moter rotation error Pick the wrong phase sequence power lines Swap any two connected lines
Right direction signal input Change the direction set
Motor torque is too small Too small relative to current setting Phase current is set correctly
Acceleration too fast Reduce the acceleration
Motor stall Ruled out mechanical failure
Does not match with the motor drive For a suitable driver
