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 speedPins 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 pinENBL+ 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 levelis active, all control negative signals will be connected together to GND. When low electricallevel is active, all control positive signals will be connected together to public port. Now givetwo 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 outputNote: When VCC=5V, R=0 When VCC=12V, R=1K, >1/8W When VCC=24V, R=2K,>1/8WR 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:SW5OFFONOFFONOFFONOFFONOFFONOFFONOFFONOFFSW6ONOFFOFFONONOFFOFFONONOFFOFFONONOFFOFFSW7ONONONOFFOFFOFFOFFONONONONOFFOFFOFFOFFSW8ONONONONONONONOFFOFFOFFOFFOFFOFFOFFOFFPULSE/REV400800160032006400128002560010002000400050008000100002000025000 2) Standstill current settingSW4 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.

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. FixingThere 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 TroublesAlarm indicator CausesMeasuresLED off turnWrong connection for powerCheck wiring of powerLow-voltages for powerEnlarge voltage of powerMotor doesn’t run, without holding torqueWrong connection of stepper motorCorrect its wiringRESET signal is effective when offlineMake RESET ineffectiveMotor doesn’t run, butmaintains holding torqueWithout input pulse signalAdjust PMW & signal levelMotor runs wrong directionWrong wires’ connectionChange connection for any of 2 wiresWrong input direction signalChange direction settingMotor’s holding torque is too smallToo small relative to current settingCorrect rated current settingAcceleration is too fastReduce the accelerationMotor stallsRule out mechanical failureDriver does not match with the motorChange a suitable driver 7.
