Product Introduction:2 Phase Digital Microstep Stepper Drive for motor's current under 2.2 AECON provides tens of models of stepper drives. From 2 phase to 3 phase, DSP digital, 24--80 DC input or 24--80VAC input, and can provide the right stepper drives to satisfy the special needs of your stepper control systems. ECON’s stepper products are well-known because of their wide choices, excellent performance, easy to use, high reliability, and low cost. The stepper drives have been used by thousands of OEM clients in the world from many of industries such as CNC machinery, medical, electronics, semiconductor, packaging, lab automation.The high performance DH series digital stepper drives are featured with extra low noise, very low motor heating, and ultra smooth motor movements at low speed. With performance and cost balanced.DH422 is the new generation high performance fully digital stepper drive which base on 32bit DSP with a advanced algorithm .the power supply range is DC18~36V. it can drive frame 42mm 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 .Product Features:2 Phase Digital Microstep Stepper Drive for motor's current under 2.2 A●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 100KHz●over voltage , under voltage, over current protectionApplications It can be used in various kinds of machines ,such as dispenser machine. floating machine3D 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 Mounting dimension（unit：mm）Product Function:2 Phase Digital Microstep Stepper Drive for motor's current under 2.2 ACurrent Setting Peak current A)RMS current (A)SW1SW2SW30.30.2ONONON0.50.4OFFONON0.70.5ONOFFON1.00.7OFFOFFON1.30.9ONONOFF1.61.1OFFONOFF1.91.4ONOFFOFF2.21.6OFFOFFOFFStandstill Current Setting SW4：OFF=Half CurrentON=Full CurrentMicrostep Setting Pul/revSW5SW6200ONON1600OFFON3200ONOFF6400OFFOFFInterface Description NameFunctionDescriptionPWRPower lightWhen power on ,the green light is on ALARMOver current/under voltage/over voltage displaying lightIf the drive Over current/under voltage/over voltage, the red light is on PUPulse inputPulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each falling edge active; 4-5V for High -level, 0-0.5V for low-levelDRDirection input DIR signal: In single-pulse mode, this signal has low/high voltage levels, representing two directions of motor rotation;+5VPulse input VCCOpto-coupler power supply, and the typical voltage is +5V. Series connect resistors (at the PU, DR, MF terminals) for current-limiting when +12V or+24V used.(should connect 1k resistor for +12V,2k for +24V)MFEnable signalEnable signal: This signal is used for enabling/disabling driver. High level for enabling the driver and low level for disabling the driver.
