The is more than a simple revision number increment—it represents a philosophical shift towards intelligent, edge-enabled industrial automation. By blending deterministic real-time control (via TSN) with flexible edge analytics (via the RISC-V co-processor), this module solves the latency-versus-bandwidth dilemma that has plagued factory networks for a decade.
Once enabled via Bluetooth settings, holding a stable throttle position for 6 to 8 seconds locks in the cruise velocity until the brake lever is tapped. Wiring Interface & Connector Map

If your facility currently operates older versions of the KCQ series, migrating to the requires careful planning.
The V4.0 model is frequently used as an upgrade or direct replacement for standard 13A controllers, offering a higher current limit for improved torque. DC 36V. Current Limit: 15A ± 0.5A. Rated Power: 350W.
Often configured for "zero start" (thumb throttle works without kicking off), though this can sometimes be toggled in the firmware. Common Use Cases & Maintenance Wiring Interface & Connector Map While holding both
Finally, v4.0 is a clear . Following semantic versioning conventions, v4.0 implies a major release. The “4” signals significant changes or a new generation, while the “.0” indicates it is a stable, feature-complete release rather than a patch or minor update (e.g., v4.1). This versioning is critical for tracking compatibility, updates, and historical provenance.
