For high speed and high precision drive of stepping motor, Ezi-STEP-ST is an unique drive that adopts a new control scheme owing to an on-board high performance digital signal processor. With an unique position estimation algorithm, it is instantaneously defects an out of synchronization in the rotor of the stepping motor, which is not an easy task in a conventional stepping motor & drive. Utilizing software damping and filtering method, high speed resolution is realized by the exciting angle control of a step angle.
Main Characteristics are:

• Sensorless Stall ( Step-out ) Detection without external sensor and it is effective at least over 300 RPM
• Software Damping ( FASTECH minimizes step motor it's own vibration at the low speed range without mechanical damper )
• Run/Stop Signal output.
• Can download max. 16 motors data base information into drivers.

 
Ezi-STEP-ST is motor and driver separate stand alone units and it can cover NEMA 8, 11, 17, 23 and 34.
