KSS KR-A5CC Stepping Motor Driver

The KSS KR-A5CC is a basic-function, cost-effective stepping motor driver designed for 5-phase stepping motors. It uses a bipolar pentagon constant current drive method and supports both full-step and half-step operation, making it well suited for general positioning and motion control applications where straightforward open-loop control is sufficient.

The driver operates on a DC 20 to 35V power supply with a maximum current of 2A, and provides a driving current range of 0.1 to 0.9A per phase, shipped with a default setting of 0.35A per phase. Additional functions include pulse input switching, full step and half step selection, and automatic current down, allowing the current to be reduced during standstill to minimise motor heating and power consumption when holding torque demands are lower.
