Danfoss Power Solutions new PC-PRO propel software enhances off-highway machine efficiency and performance

Danfoss Power Solutions today announced the launch of its PC-PRO software for hydrostatic transmissions. PC-PRO is a single-path propel solution that delivers precise speed and torque control in both automotive and non-automotive applications.

It incorporates high-tech features such as advanced auto-inch, smart calibration routines, and advanced all-range ECO mode, enhancing machine efficiency, precision, and consistency while reducing startup time. PC-PRO is ideal for off-highway machinery with hydrostatic drives, such as wheel loaders, telehandlers, dumpers, feeder mixers, combines, harvesters, and forestry equipment. 

PC-PRO’s advanced all-range ECO mode cuts energy use and improves operator comfort. ECO mode automatically activates at medium to high vehicle speeds, reducing engine speed proportionally while maintaining constant vehicle speed. This lowers fuel consumption, reducing costs and improving machine uptime. It also minimizes noise emissions, creating a quieter, more comfortable environment for those working in the cab and nearby. 

The system’s innovative work function interface, featuring advanced auto-inch and external engine RPM request, ensures the machine delivers both power and precision. When the engine speed rises in response to external requests — a command from the work function subsystem, for example — auto-inch automatically reduces the hydrostatic pump command, delivering smooth, precise movement while maintaining vehicle speed. The external engine RPM request ensures the machine delivers power when needed. This smart feature automatically increases engine speed when work functions or steering demand higher oil flow, ensuring smooth, powerful operation.

PC-PRO’s smart calibration routines enable fast startup and consistent performance under varying conditions. The robust pump and motor calibration procedures compensate for natural product variances such as the current-to-speed/displacement relationship. This enables consistent, repeatable driving behavior across the vehicle fleet. The intuitive calibration routines eliminate cost- and time-intensive assembly line adjustments and enable OEMs to easily transfer parameters from machine to machine, reducing commissioning time.

“Our PC-PRO software offers power when you need it, precision when you demand it, and all‑around smarter performance. As machines become more advanced, OEMs need propel solutions that are equally intelligent and adaptable. PC‑GO and PC‑PRO represent Danfoss’ next‑generation propel control platform, unifying our capabilities into two core software programs built for long‑term evolution. These modern solutions, designed on today’s safety and security architecture, deliver significant enhancements and clear advantages for both OEMs and end users,” said Hans-Hermann Bloecker, Manager, Product Application Engineering, Hydrostatics, Danfoss Power Solutions.

PC-PRO supports multiple displacement control types, including electric displacement control (EDC), non-feedback proportional electric control (NFPE), and Danfoss’ new Hybrid Load Control (HLC). The software is offered on the Danfoss PC036 controller, available now, and the PC062 controller, coming soon. PC-PRO is configurable using the Danfoss PLUS+1® service tool, enabling quick and simple customization. Compatible hardware includes Danfoss MP1P and H1P hydrostatic pumps and H1B proportional motors, plus optional DST pressure sensors.

The initial option package provides a foundation of advanced drive features, with more to be added over time. PC-PRO also incorporates all the proven capabilities of Danfoss’ PC-GO software, including basic drive features such as engine overspeed protection, pump and motor overspeed protections, temperature de-rate, anti-stall, load limiter, and cold start protection, plus comfort features such as cruise control, deceleration assist, and more. PC-PRO will be Cyber Resilience Act and Machinery Regulation compliant with the effective dates of the legislation.
