UIM240

Stepper Drives

UIM240XX are micro-high-performance stepping motor drivers featuring small size that can be mounted onto NEMA 17/23/34/43 series stepping motor seamlessly through corresponding flanges.

The UIM240L02 provides 0-2A adjustable peak current; UIM240C04 provides 1.5-4A adjustable peak current; UIM240C08 provides 3-8A adjustable peak current. Its high-speed current compensates for the impact caused by back-EMF when the motor is running at high speed.

UIM240L02 uses 12-28VDC for power supply while UIM240XX series drivers work on 12-38 VDC power supply. Drive enclosure is made of die-cast aluminum which provides rugged, durable protection and improves the heat dissipation.

1V+Positive Voltage: 12-48 VDC (Note: Max voltage is different between 242Lxx, 242Cxx and 242Hxx)
2GNDGround voltage: 0V (Positive and negative can not be wrong)
3VCCCommon anode input, positive electrode of pulse, direction, and off-line signals is connected to the terminal
4DIRDirection signal input, High/ Low-level key for rotation direction control and vacancy for the high level
5STPStep pulse input, the falling edge is a valid pulse
6ENAOff-line signal input. Low level means the rotor in a free state, high or vacant means the motor be controlled
