Nema 23 stepper motor: Technical Specifications Part No. 23HS9442 Frame Size NEMA23 Phase 2 Phase Step Angle 1.8 degree Current 4.2 A Rated Voltage 3.78V Resistance 0.9 Ohm/phase Inductance 3.8 mH/phase Holding torque 435 oz-in (2.8N.m) Detent torque 12N.cm Rotor inertia 800 g.cm² Number of wire leads 4 Weight 1.7 kg Length 112 mm Shaft Single Shaft Front shaft length 21mm The diameter for motor shaft 8mm Matched drive DM542A Wiring dragram: RED A+ , GRN A-, RED B+, BLU B- 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: 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 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 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 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, butmaintains 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.
