CNC Control 4Axis Stepper Driver,24-80VDC/7.8A/256Micro Description Welcome to our website: http://www.longs-motor.com Email:cherry@longs-motor Skype:chenpeijuan2010 MSN:chenpeijuan2010@live.cn This item includes: 4 pcs Stepper motor driver--DM860A, High Perfermance Stepper Driver DM860A Up to7.8A, 24-80VDC 1 pc Breakout Board 1 pc Parrallel Cable ( 25 pins) free offering when you bought above Detailed pic: Technical Specification: 1. Stepper motor driver DM860A: http://www.longs-motor.com/ProductsView.asp?id=273&pid=83 Introduction: DM860A is a type of two-phase hybrid stepping motor driver, The drive voltage of which is from 24VDC to 80VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 57mm to 110mm outside diameter and less than 8.0A 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 DM860A 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: l High performance, low price l Average current control, 2-phase sinusoidal output current drive l Supply voltage from 24VDC to 80VDC l Opto-isolated signal I/O l Overvoltage, under voltage, overcorrect, phase short circuit protection l 14 channels subdivision and automatic idle-current reduction l 8 channels output phase current setting l Offline command input terminal l Motor torque is related with speed, but not related with step/revolution l High start speed l High hording torque under high speed Electrical specification: Input voltage 24-80VDC Input current < 6A Output current 2.8A~7.8A Consumption Consumption:80W; Internal Insurance:10A Temperature Working Temperature -10~45°C; Stocking temperature -40°C~70°C Humidity No condensation, no water droplets gas Prohibition of combustible gases and conductive dust weight 500G 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 ON OFF ON OFF ON OFF ON OFF ON OFF ON OFF ON OFF SW6 ON ON OFF OFF ON ON OFF OFF ON ON OFF OFF ON ON SW7 ON ON ON ON OFF OFF OFF OFF ON ON ON ON OFF OFF SW8 ON ON ON ON ON ON ON ON OFF OFF OFF OFF OFF OFF PULSE/REV 400 800 1600 3200 6400 12800 25600 51200 1000 2000 5000 10000 25000 50000 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 2.80 2.00 OFF ON ON 3.50 2.50 ON OFF ON 4.20 3.00 OFF OFF ON 4.90 3.50 ON ON OFF 5.70 4.00 OFF ON OFF 6.40 4.60 ON OFF OFF 7.00 5.00 OFF OFF OFF 7.80 5.60 4) Semi-flow function: Semi-flow function is that there is not step pulse after200 ms, the driver output current automatically reduced to 40% of rated output current, which is used to prevent motor heat. 4. Pins of motor & power: Motor and power pins 1 A+ Motors wiring 2 A- 3 B+ 4 B- 5,6 DC+ DC- Power supply Power supply :DC24-80VDC The peak input current can not up to 6A 2. Breakout board: Description: • Built in DB25 male connector. • DB25 Output Pin:P1,P2,P3,P4,P5,P6,P7,P8,P9,P14,P16,P17. • DB25 Input Pin: P10,P11,P12,P13,P15. • DB25 GND Pin: P18-P25. • Power supply: +5V DC. • Built in C-class Optical-coupler. • High quality with Surface-mount Tech.
