UIM 241 stepper motor controller with RS232 interface

UIM24104/24108 is miniature, intelligent stepper motor controller using the RS232 protocol for communicating with user devices/controllers. They can be mounted onto Nema 17, 23, 24 and 34 stepper motors seamlessly through corresponding flanges. The thickness of these stepper controllers is less than 14 millimeter. The embedded high performance DSP microprocessor accepts user commands in ASCII code style through RS232 protocol. The structure of the instructions (i.e. commands from user) is simple, straightforward and fault-tolerating. Users are not required to have the knowledge of stepper motor driving. Enclosures of UIM24104/24108 are made of die-cast aluminum which provide a rugged and durable protection to the stepper controller and improve the heat dissipation.

RS232 Interface

Bipolar constant current
The highest output power and motor utilization for a given motor is achieved with the bipolar constant current driver. DC-losses is kept at a minimum due to maximum utilization of the copper in the winding and no power losses from leakage inductance and snubbing circuits since every winding only consists of one part.
