Two Phase Closed-loop Stepper Motor Driver

It's used to control NEMA17 and NEMA23 closed-loop stepper motor

1. Voltage input range: DC: 20V ~ 50V (recommended 36V or more)
2. Maximum peak current: 6A
3. Subdivision range: 400 ~ 51200ppr
4. Pulse form: pulse + direction, CW / CCW
5. Impulse response frequency: 0 ~ 200kHz
6. Logic input current: 10 ~ 20mA
7. Power-on parameter auto-tuning function
8. Closed-loop vector control to ensure that the motor high-speed high-torque output, while ensuring that the motor does not lose step
9. With over-voltage, over-current, tracking error tolerance and other protection functions

Driver terminal description

1) Power terminal definition

Symbol	Name
A+	A-phase motor winding positive terminal
A-	A phase motor winding negative terminal
B+	B-phase motor winding positive terminal
B-	B-phase motor winding negative terminal
+VDC	Power access positive terminal
GND	Power access ground

2) Driver Encoder Terminal Definition:

Symbol	Color	Explanation
EB+	Yellow	Motor encoder B phase positive input
EB-	Green	Motor encoder B phase negative input
EA+	Black	Motor encoder A phase positive input
EA-	Blue	Motor encoder A phase negative input
VCC	Red	Encoder + 5V input
EGND	White	Encoder power ground

3) Control signal port

Name	Explanation
PUL＋	Pulse input signal: pulse effective edge adjustable, the default pulse rising edge is valid; in order to reliably respond to the pulse signal, the pulse width should be greater than 1.2μs. Such as the use of +12 V or +24 V when the need to string 3K resistance
PUL－
DIR＋	Direction input signal: high / low level signal, in order to ensure reliable reversing of the motor, the direction of the signal should be preceded by pulse signal at least 5μs to establish, such as the use of +12 V or +24 V string 3K resistor.
DIR－
ENA＋	Enable control signal: This input signal is used to enable or disable. When ENA +, ENA- have input, the drive will cut off the motor phase to make the motor in a free state. When this function is not required, the terminal can be left floating. Such as the use of +12 V or +24 V when the need to string 3K resistance
ENA－
Pend+	Positioning completion signal positive side
Pend-	Positioning completion signal negative
ALM＋	Alarm output positive terminal
ALM－	Alarm output negative terminal
