X RX A Bl El P Die cast aluminum enclosure DESCRIPTION UIM240XX Miniature Stepper Motor Drivers are series miniature high performance stepper motor controllers They can be mounted onto NEMA 17 23 34 42 series stepper motor seamlessly through corresponding flanges The thickness of these controllers is less than 15 mm The UIM24002 outputs 0 2A adjustable current the UIM 24004 outputs1 5 4A adjustable current and the UIM24008 outputs 3 8A adjustable current Their mixed decay current control reduces the back EMF effect under high motor speed and improves the performance Except that UIM24002 takes 10 35VDC input UIM240XX series controllers work on 12 40VDC input The enclosure is made of die cast aluminum which provides a rugged durable protection and improves the heat dissipation MYOSTAT CA Page 3 UIM24002 04 08 TERMINAL DESCRIPTION Figure 0 1 Wiring Terminal Current Adjusting Trimmer ati y fl f i J iy fl y j i ae z To avoid loss of screws please always keep screws tightened Control Terminals OCT en OOOO Note 1 Input is considered high level if this terminal is not connected 2 Low level pulse duration should gt Aus 3 An active low level input shuts down power supply to the motor High level input or left open makes the controller fully working When awaken from shutdown mode wait 1 millisecond before sending pulse Motor Terminals Connect to the stepper
