This item includes:


3 pcs stepper motor driver DQ542MA 4.2A 50V 128microsteps

1 pc breakout board&cable is free




1)stepper motor driver

 
Introduction:
DQ542MA is a type  of two-phase hybrid stepping motor driver, the drive voltage of it is from
18VDC to 50VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with
42mm to 86mm outside diameter and less than 4.0A phase current. This circuit that it adopts
is smiliar to the circuit of servo control which enables the motor run smoothly almost without
noise and vibration. Holding torque when DQ542MA runs under high speed, is also significantly
higher than the other two-phase driver, what’s more, the positioning accuracy is also higher.
It is widely used in middle and big size numerical control devices such as curving machine,
CNC machine, and computer embroider machine, packing machines and so on.
 
 
 
Features:
  •   High performance, low price
  •   Average current control, 2-phase sinusoidal output current drive
  •   Supply voltage from 18VDC to 50VDC
  •   Opto-isolated signal I/O
  •   Overvoltage, under voltage, overcurrent, phase short circuit protection
  •   15 channels subdivision and automatic idle-current reduction
  •   8 channels output phase current setting
  •   Offline command input terminal
  •   Motor torque is related to speed, but not related to step/revolution
  •   High start speed
  •   High holding torque under high speed

Pins assignments and description:
 
1)   Connector Pins  Configurations
 

Pin Function
                Details                                                          
PUL +,PUL-
Pulse signal, PUL+ is the positive end of pulses  input pin
                  PUL- is the negative end of pulse  input pin
 
DIR+,DIR-
DIR signal: DIR+ is the positive end of direction input pin
                 DIR- is the negative end of direction input pin
ENBL+
 
Enable signal:  ENBL+ is the positive end of direction input pin. This signal is used for enabling/disabling the driver. High level for enabling the driver and low level for disabling the driver.
ENBL-
ENBL- is the negative end of direction input pin. Usually left unconnected (enabled)

 
 
 
2) Pins wiring diagram:
PC’s control signals can be active in high and low electrical level. When the high electrical level
is active, all control negative signals will be connected together to GND. When low electrical
level is active, all control positive signals will be connected together to public port. Now give
two examples(  Open collector &PNP), please check them:

 
 
 
3.Function choice ( Using DIP pins to achieve this function)
1) Micro step resolution is set by SW 5,6,7,8 of the DIP switch as shown in the following table:

2) Standstill current setting
SW4 is used for this purpose. OFF meaning that the standstill current is set to be half of the
selected dynamic current and ON meaning that standstill is set to be the same as the selected
dynamic current.
 
 
3) Output current setting:
The first three bits (SW 1, 2, 3)of the DIP switch are used to set the dynamic current.

4) Semi-flow  function:
Semi-flow function is that there is not step pulse after 500 ms, the driver output current
automatically reduced to 70% of rated output current, which is used to prevent motor heat.

5. Mechanical Specification:
To have 20mm of space around, cannot be placed next to other heating devices. Whats more, 
avoid dust, oil mist, corrosive gas, heavy humidity and high vibration.

6. Adjustment of troubleshooting

1) , the status on light’s indication
PWR: green, normal work light.
ALM: red, failure light, the motor with phase short-circuit, overvoltage and under-voltage  
protection.

2) Troubles

Alarm indicator
 
Reasons
Measures
LED off turn
Wrong connection for power
Check wiring of power
Low-voltages for power
Enlarge voltage of power
Motor doesn’t run, without holding torque
Wrong connection of stepper motor
Correct its wiring
RESET signal is  effective when offline
Make RESET ineffective
Motor doesn’t run, but maintains holding torque
Without input pulse signal
Adjust PMW & signal level
Motor runs wrong direction
Wrong wires’ connection
Change connection for any of 2 wires
Wrong input direction signal
Change direction setting
Motor’s holding torque is too small
Too small relative to current setting
Correct rated current setting
Acceleration is too fast
Reduce the acceleration
Motor stalls
Rule out mechanical failure
Driver does not match with the motor
Change a suitable driver

 
7. Driver wiring 
A complete stepper motor control system should contain stepper drives,
DC power supply and controller (pulse source). The following is a typical
system wiring diagram
