3 PCS Nema 34 Stepper Motor with Dual shaft 1600oz-in holding torque. 3PCS Stepper Driver with 7.8A replacing MD882. 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. 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. 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. The first three bits (SW 1, 2, 3)of the DIP switch are used to set the dynamic current. Closest to your motors required current. 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. Pins of motor & power.The peak input current can not up to 6A. Great News for USA customers! Our Stepper Motors are used on small to mid-sized CNC mills & milling machines, CNC lathes, Pick-n-place machines, Laser Engravers and Laser Cutters, Vinyl Sign Cutters, CNC Plasma Cutters, and CNC Foam Cutters.
These motors have been used in precision telescope positioning systems and robots.
