Description

 

UIM24204 and UIM24208 are miniature stepper motor controllers with CAN network capability. Through a CAN-RS232 converter (UIM2501), user device can command multiple UIM242 controllers through RS232 using ASCII coded instructions. Instructions are simple, intuitive and fault-tolerating. User is not required to have knowledge on stepper motor driving and CAN network.

 

UIM242 controller’s architecture comprises communication system, basic motion control system,

absolute position counter, and real-time event-based change notification system. Embedded 64-

bit calculation precision DSP controller guarantees the real-time processing of the motion control and change notifications.

 

There are 3 optional advanced modules: Advanced Motion Control Module, Sensor Input Control Module, and TTL Output Control Module. With UIM242’s Advanced Motion Control, selected NEMA17/23 motors can ramp up to 6600 RPM in 0.5 seconds and 4000 RPM in 0.25 seconds (online video available for downloading).
