Kingsni Technology Explains Key Factors in Selecting Stepper Drive Microstep Resolution

Chengdu, Sichuan, China - October 30, 2026

In a stepper motor control system, the microstep resolution (also known as step subdivision) of the drive is a critical parameter. The higher the microstep resolution, the smoother the motor runs and the higher the positioning accuracy. But how do you select the optimal microstep resolution in practice? Kingsni Technology, backed by years of experience in extremeenvironment motion control, offers practical recommendations.

Recommended Microstep Resolution: 4000 or 10000

Extensive testing has shown that for most industrial applications, setting the stepper drive's microstep resolution to 4000 or 10000 delivers outstanding performance.

Reason 1: Higher Torque at High Speeds

At the same motor speed, selecting 10000 microsteps results in significantly higher output torque compared to selecting 1000 microsteps. This means that in highspeed scenarios, a higher microstep resolution preserves more torque margin, effectively prevents missed steps, and improves equipment stability and processing efficiency.

Reason 2: Smoother LowSpeed Operation

Many users report that when the microstep resolution is as low as 1000, the motor exhibits strong vibration and very low torque at low speeds (e.g., below 10 rpm), making operation impossible. Increasing the resolution to 10000 dramatically reduces lowspeed vibration while providing sufficient torque to meet load demands. This is especially important for precision positioning or lowspeed creeping applications such as semiconductor inspection and biomedical sampling.

Constraint: Maximum Pulse Frequency of the PLC

The microstep resolution cannot be increased indefinitely. It is limited by the maximum output pulse frequency of the host controller (e.g., a PLC). The input pulse frequency required by the stepper drive equals motor speed (revolutions per second) times microstep resolution. For a given maximum motor speed, a higher microstep resolution demands a higher pulse frequency. If the PLC cannot provide the required frequency, the resolution must be lowered. Therefore, choosing 4000 or 10000 strikes a good balance between performance and compatibility.
