Chip with Stepper Motor Know How. The StepperChip sets new standards for the digital control of stepper motor drives. Utilizing a state-of-the-art digital signal processor (DSP) made it possible to develop new procedures and control technologies. All necessary functionality to operate a stepper motor are on board the chip. So even without having specific know how it is now possible to simply design a high performance stepper drive. The StepperChip is a series product already implemented in a complete line of digital power drives. The application field of the chip are OEM-markets that design their own stepper drives. The target sales groups are high volume OEMs or manufacturers of application oriented controls such as hose pumps, pin stampers, lab and measuring devices etc.

AUTOMATIC CONTROLLER SETUP:
At power on, the drive automatically tunes the motor operating parameters to achieve optimal dynamic.

BOOST AND CURRENT REDUCTION:
A variable boost function adds extra current offset to set current value allowing higher acceleration rates. The current reduction reduces the motor current at stand still.

DYNAMIC PARAMETER ADJUSTMENT:
Several conditions are continuously monitored and the operating parameters are automatically adjusted. As a result dynamic positioning moves are 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.

DIGITAL PHASE CURRENT CONTROLLER:
The digital phase current controller optimizes the performance such as low resonance run, high step angle accuracy and high and constant torque from step to step.
