DH3422MA

Description

DH3422MA
Introduction
1. overview
DH3422MA is the new generation high performance fully digital stepper drive which base on 32bit DSP with a advanced algorithm .the power supply range is AC110~220V. it can drive frame 86-130mm 3 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 input
●the response frequency is up to 300KHz
●over voltage , under voltage, over current protection
●support PU+DIR pulse mode and CW/CCW pulse mode
●Support 5V/24V signal (PU DR MF) input
3. applications
It can be used in various kinds of machines ,such as cnc router, floating machine, packaging machine,3D printer, labelling machine,cnc milling/lathe, 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

Name	function	description
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
24PU+	24Vpulse input  VCC	Connect to 24V pulse VCC (support PLC 24V+ )
5PU+	5V pulse input VCC	Connect to 5v pulse VCC
PU-	Pulse input negative	Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each falling edge active. In CW/CCW pulse mode,5PU and PU- are CW input
24DR+	24V direction input VCC	Connect to 24V pulse VCC (support PLC 24V+ )
5DR+	5Vdirection input VCC	Connect to 5v pulse VCC
DR-	Direction input negative	DIR signal: In single-pulse mode, this signal has low/high voltage levels, representing two directions of motor rotation; In CW/CCW pulse mode,5DR and DR- are CCW input
24MF+	24V enable input VCC	Connect to +24V signal power supply
5MF+	5V enable input VCC	Connect to +5V signal power supply
MF-	Enable input 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 left UNCONNECTED (ENABLED).
RDY+	Drive ready signal output VCC	Drive ready output signal ,if no fault，this output is off ,if fault,the output is on .after power on ,the alarm light will be on 10ms,and the RDY+/RDY will be on too (10ms)
RDY-	Drive ready signal output negative	RDY+,RDY- output current is 50MA,the max voltage is 50VDC
AC	AC power supply input	AC110-220V，the max input power is AC240V
N	NC
U	Motor  U	Motor  U，
V	Motor  V	Motor  V
W	Motor  W	Motor  W

！Note
1: Connect power supply rightly ,cant exceed 240VAC
2: please keep the pulse cable from the motor cable and power cable ,in case the interference
3:if the alarm light is on ,please check it after power off
A :the power supply range is 110V—220VAC or not ï¼›B:is there any short on motor wire or others ?
