Description
UIM240xx Miniature Stepper Driver is a series of miniature, high performance stepper motor driver. They can be mounted onto NEMA 17 / 23 / 34 and 42 series stepper motor seamlessly through corresponding flanges. The thickness of these Drivers is less than 14 mm. UIM24002 is capable to provide 0-2A adjustable current. UIM 24004 is capable for 1.6-4A adjustable current output and UIM24008 is capable for 2A-8A adjustable current output. 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 Drivers can work on 12 to 40VDC input. Enclosure is made of die-cast aluminum which provides a rugged durable protection and improves the heat dissipation.
Description of stepper driver Screw Terminals
Terminal No. / Color | Description | Input | |||
MIN NOM MAX | UNIT | ||||
1 / Red | V+ | Supply voltage | UIM24004-8 | 12 40 | VDC |
UIM24002 | 10 35 | ||||
2 / Black | GND | Supply voltage ground | 0 | VDC | |
3 / White | Vcc | Opto-coupler common anode | 5(1) | VDC | |
4 / Green | DIR | Direction input(2) | GND Vcc | VDC | |
5 / Cyan | STEP | Stepping pulse input(3) | GND Vcc | VDC | |
6 / Blue | EN | Enable the Driver(4) | GND Vcc | VDC | |
Note:
(1) Please refer to “optically isolated input interface” section for details.
(2) Input is considered high level if this terminal is not connected.
(3) Low-level pulse duration should > 8μs. Maximum pulse frequency is 50 KHz.
(4) An active low-level input shuts down power supply to the motor. High-level input or left open makes the Driver fully working. When awaken from shutdown mode, wait 1 millisecond before sending pulse.
Note: To avoid damaging, make sure the phase winds are connected correctly. Resistance between leads of different phases is usually > 100KW. Resistance between leads of the same phase is usually < 100W.
