hybrid servo information

Conventional open-loop stepper systems work in open-loop mode, i.e. position control without feedback. When stepper motors run under load in an open loop, a potential loss of synchronization between commanded and actually executed steps can occur, known as "stall" or "step loss". In the past, this was corrected by adding a feedback device such as an optical encoder that monitors the "current" position. However, this conversion can only alert, not correct, step losses.

When an application requires real-time position control during motion, engineers have been forced to rely on servo systems and the complexity and cost associated with them. In many applications, because traditional servo systems lack high torque compared to stepper motor systems, expensive planetary gears had to be added to achieve the desired torque.

Through the implementation of high-resolution encoders, which feedback the motor position every 25 microseconds, closed-loop stepper drives guarantee real-time controlled position accuracy without loss of steps as with open-loop stepper motor systems.

Attention: There are systems which call themselves "closed-loop" and also work with encoders, but which have no field-oriented control including sinusoidal commutated current control. Although they check the step position, they cannot compensate for step angle errors during movement.

Our closed-loop systems have field-oriented control, i.e. they compensate step losses during movement and correct load angle errors within a full step!

Unlike open-loop stepper motor systems where the current is constant, closed-loop stepper motor systems vary the output current and are optimized based on motion and load. As a result, closed-loop stepper motor systems generate higher torque, less motor heating, less vibration and less noise than open-loop stepper motor systems.

Compared to brushless or brush servo systems, the costs for closed-loop stepper motor systems are significantly lower. In addition, they offer much higher torque, easy adjustment and configuration, no overshoot, and no in- and outward oscillation (hunting). In many low to medium applications, closed-loop stepper motor systems can be the better solution than servo systems.
