2. Stepper motor driver DM542A:
Introduction:
DM542A is a type of two-phase hybrid stepping motor driver, The drive voltage of which 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 similar to the circuit of servo control which enables the motor run smoothly almost without noise and vibration. Hording torque when DM542A run 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, overcorrect, 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 with speed, but not related with step/revolution
·
High start speed
·
High hording 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:
Fig 1. Input port circuit (Yang connection)
PC open connector output
Fig. 2 Input port circuit ( Yin connection)
PC PNP output
Note: When VCC=5V, R=0
When VCC=12V, R=1K, ＞1/8W
When VCC=24V, R=2K,＞1/8W
R must connect in the control signal part.
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. Select a setting
Closest to your motor’s required 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.
4. Power connections
(1)+V、GND：Power Supply.
+V: Power supply, 16~50 VDC, Including voltage fluctuation and EMF voltage. The max current is 5A.
(2) A+  A-  B+  B-：Connecting 2 phase stepper motors.
The driver & 2-phase hybrid stepping motor use four-wire connection, the motor can be connected in parallel & series bipolar. As for bipolar connection, it is higher performance with high-speed, but the current of driver is larger (it is 1.73 times more than the motor’s winding current).
Connecting in series, the driver’s current is equal to the motor winding one.
5. Fixing
There should be 20mm of space, it can’t be placed next to other heating devices, to avoid dust, oil mist, corrosive gas, humidity and strong vibration places.
(Unit=mm)
6. Troubleshooting
1, the status on light’s indication
RUN: green, normal work light.
ERR: red, failure light, the motor with phase short-circuit, overvoltage and under-voltage protection.
2 Troubles
Alarm indicator
Causes
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).
3.Power Supply
The power is 350Watts, and the output voltage is 36VDC.
