DH860
Introduction
1. overview
DH860 is the new generation high performance fully digital stepper drive which base on 32bit DSP with a advanced algorithm .the power supply range is AC24~80V. it can drive frame 57---110mm 2 phase stepper motor .
Ultra low noise and high smoothness at middle/low speed ,and high torque at high speed, which can be applied to different speed control applications. adopt smooth and accurate sinusoidal current vector control technology ,which make motor low heat .
2. features
●new generation 32bit DSP
●good smoothness ,low noise ,low heat
●build-in micro step setting
●build-in current setting
●the standstill current can be set to 50%
●opto-isolated differential pulse
●the response frequency is up to 300KHz
●over voltage , under voltage, over current protection
3. applications
It can be used in various kinds of machines ,such as dispenser machine. floating machine
3D printer, labelling machine, medical machine, laser cut machine, and so on ,its unique features make it an ideal solution for the applications which require low noise ,low vibration, low heat and high precision

PWR	Power light	When power on ,the green light is on
ALARM	Over current/under voltage/over voltage displaying light	If the drive Over current/under voltage/over voltage, the red light is on
PU+	Pulse positive	Pulse signal: In single pulse (pulse/direction) mode, this represents pulse signal, each falling edge active; 4-5V for High -level, 0-0.5V for low-level Series connect resistors for current-limiting when +12V or +24V used.(should connect 1k resistor for +12V,2k for +24V)
PU-	Pulse negative	Pulse signal: In single pulse (pulse/direction) mode, this represents pulse signal, each falling edge active; 4-5V for High -level, 0-0.5V for low-level
DR+	Direction  positive	DIR signal: In single-pulse mode, this signal has low/high voltage levels, representing two directions of motor rotation; Series connect resistors for current-limiting when +12V or +24V used.(should connect 1k resistor for +12V,2k for +24V)
DR-	Direction  negative	DIR signal: In single-pulse mode, this signal has low/high voltage levels, representing two directions of motor rotation;
MF+	Enable positive	Enable signal: This signal is used for enabling/disabling driver. High level for enabling the driver and low level for disabling the driver. Usually leftUNCONNECTED (ENABLED). Series connect resistors for current-limiting when +12V or +24V used.(should connect 1k resistor for +12V,2k for +24V)
MF-	Enable negative	Enable signal: This signal is used for enabling/disabling driver. High level for enabling the driver and low level for disabling the driver. Usually leftUNCONNECTED (ENABLED).
AC1	AC Power	AC24-80V
AC2	AC Power
A+,A-	Motor A phase	Connect to   Motor A phase
B+,B-	Motor B phase	Connect to   Motor B phase

！Note
1: Connect power supply rightly ,cant exceed 80VAC
2: If the control signal (PU, DR, MF ) is over 5V ,please connect resistors (at the PU+, DR+, MF+ terminals) for current-limiting.
3:if the alarm light is on ,please check it after power off
A :the power supply range is 24V—80VAC or not ? B:is there any short on motor wire or others ?
