This power drive sets new standards for the digital control of stepping motors. Utilizing a state-of-the-art digital signal processor (DSP) made it possible to develop new procedures and control technologies. The result is a low cost and ultra compact power drive especially efficient in highly dynamic applications. The robust drive is suitable for rough industrial environments. A wide range of 2-phase and 3-phase stepping motors (sizes NEMA23,24 and 34) can be covered.

AUTOMATIC CONTROLLER SETUP:
At power on, the drive automatically tunes the motor operating parameters to achieve optimal dynamic and smooth drive running performance. Specific power drive know how is therefore not required.

BOOST AND CURRENT REDUCTION:
A variable boost function monitors the actual acceleration rate and adds an additional current offset to the set current value permitting higher acceleration rates. The current reduction reduces the motor current at stand still to 60%.

DYNAMIC PARAMETER ADJUSTMENT:
Several conditions are continuously monitored and the operating parameters are automatically adjusted. As a result the motor torque range stretches and dynamic positioning moves are also possible in the higher speed range.

STAND BY MODE:
Down to stand still the power drive gradually switches into the stand by mode. The motor is absolutely quiet and this with full torque. A big advantage in office and lab environments.

DIGITAL PHASE CURRENT CONTROLLER:
The fully digital power drive design meaures the phase current directly in the motor windings resulting in optimal performance such as low resonance run, high step angle accuracy and high and constant torque from step to step.
