    This Tech Tip will help you select the proper method for your stepper application by covering the strengths and traps of voltage to frequency conversion and other methods of pulse generation for stepper control.

TRUE STEPPER CLOSED-LOOP MOTION CONTROL, CAN IT BE DONE?
    With any motor closed loop mode is possible, but the added cost to ensure proper closed loop operation of a stepper is generally greater than using a motor designed to operate in closed loop directly. Before you choose closed-loop for your stepper application take a look at the issues raised in this Tech Tip.

PLUG AND PLAY WITH HIPERFACE, BY STEGMANN
The standard interface between motor feedback systems and drives
With the introduction of digital speed control devices, a new age is beginning for motor feedback systems. In the past, the control was the main determinant of drive system performance; now however, servo motor drive manufacturers agree that the performance of today's digital drive is largely determined by the performance of the feedback device used in their systems.

Clearly, previous feedback solutions, such as resolver technology and conventional encoders, no longer meet the increasing market demands for higher accuracy and resolution, lower P factors, and easily adjustable commutation information -- all of which must be available in a single, small, easily mountable package.

Fortunately, the new innovative HIPERFACE® feedback systems, patented by STEGMANN, meet and exceed these requirements in every respect.
