1. Nema 34 stepper motor
2. Stepper motor driver DM860A
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

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:

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

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.
