24V~75VDC 0.1A-7.2A Stepper Motor Driver JKD7208S For Nema34
Stepper Motor
General introduce:
JKD7208S is a new digital stepper motor driver by JKONGMOTOR. It
adopts the latest 32-bit DSP digital processing technology. The
drive control algorithm adopts advanced variable current technology
and advanced frequency conversion technology. The driver has small
heating, small motor vibration and stable operation. Users can set
any subdivision within 200 ~ 51200 and any current value in the
rated current to meet the application needs in most occasions.
Thanks to the built-in micro-subdivision technology, the
subdivision effect can be achieved even under the condition of low
subdivision. The operation is smooth and the noise is ultra-small
under low, medium and high speed. The driver integrates the
parameter auto-adjust function, which can automatically generate
optimal operating parameters for different motors to maximize the
performance of the motor.

Interface description
1) Control signal interface circuit
Name | Function |
PUL+ | Pulse signal: pulse rising edge is effective; In PUL high level,voltage is 4.5 ~ 28Vdc, and the low level, voltage is 0 ~ 0.5v. In order to reliably respond to the pulse signal, the pulse width should be greater than 1.5μs |
PUL- | |
DIR+ | Direction signal: high/low level signal, to ensure reliable commutation of motor, directional signal should be established before the pulse signal at least 2μs. The initial direction of the motor is connect to motor wiring, change winding (e.g., A +, A - exchange) can change the direction of the motor running, In DIR high level,the voltage is 4.5 ~ 28 VDC,in low level,voltage is 0 ~ 0.5 V. |
DIR- | |
ENA+ | Enable signal: this input signal is used to enable or prohibit. ENA+ connect 4.5 ~ 28Vdc, ENA- connect low level (or internal optical coupling), the actuator will cut off the electrical current to keep the motor in a free state and the stepper pulse is not responsive. When this function is not required, the enable signal can be suspended. |

2) High voltage interface
Name | Function |
GND | DC power grounding |
+Vdc | DC power positive, dc 24~75 VDC, recommended for 48Vdc. |
A+,A- | Motor A phase coil interface |
B+,B- | Motor B phase coil interface |
3) 232 Communication interface
It is possible to connect a PC or STU debugger with a dedicated
serial cable, and forbid charged plug. Through STU or the PC
software ProTuner, the subdivision and current value, effective
edge and single double pulse all can be set, and can also be used
for the elimination and adjustment of the resonance point.
