4 pcs Nema34 Stepper motor driver 7.8A 256micsteps. 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, whats 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. L High performance, low price. L Average current control, 2-phase sinusoidal output current drive. L Supply voltage from 24VDC to 80VDC. 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 hording torque under high speed.No condensation, no water droplets. Prohibition of combustible gases and conductive dust. Pulse signal, PUL+ is the positive end of pulses input pin. PUL- is the negative end of pulse input pin. DIR signal: DIR+ is the positive end of direction input pin.
DIR- is the negative end of direction input pin. 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- is the negative end of direction input pin.PCs 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. Input port circuit (Yang connection). 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, 1/8W.
R must connect in the control signal part. 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 settingSW4 is used for this purpose. OFF meaning that the standstill current is set to be half of the selected dynamiccurrent 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 settingClosest to your motors required current. 4 Semi-flow function:Semi-flow function is that there is not step pulse after200 ms, the driver output current automaticallyreduced to 40% of rated output current, which is used to prevent motor heat.Pins of motor & power. 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. 1 , the status on lights indication PWR: green, normal work light. ALM: red, failure light, the motor with phase short-circuit, overvoltage and under-voltage protection.
Motor doesnt run, without holding torque. Wrong connection of stepper motor. RESET signal is effective when offline.
Adjust PMW & signal level. Change connection for any of 2 wires.
Motors holding torque is too small. Too small relative to current setting.
Driver does not match with the motor. 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. 3.4 PCS Power supply 350W-60VDC.The power is 350W, the output voltage is 60VDC. 4.1 PCS Breakout board.
P2 P3 is set to X-axis for the X-axis pulse. P4 P5 is set to Y-axis, Y axis pulse. P6 P7 is set to Z-axis Z-axis pulse. The other can be set to A B C axis. A-axis pulse P8 P9 is set as the A axis.P14 is set to B-axis B-axis pulse P1. P16 P17 is set to C-axis, C axis pulse. Can also be set to the spindle control signal \ electrical permit. Input interface for the P10 P11 P12 P13 P15. 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. High quality with Surface-mount Tech.
