Danfoss enhances hydrostatic drives with PC-PRO propel software

New control software improves speed and torque precision, reduces energy consumption and simplifies calibration for off-highway machinery.  www.danfoss.com Off-highway machinery, mobile hydraulics, and hydrostatic transmission systems require precise control of speed and torque to ensure efficiency and consistent performance under varying load conditions. In this context, Danfoss Power Solutions has introduced PC-PRO, a propel control software designed for hydrostatic drives, combining advanced control functions with simplified commissioning. The software is developed as a single-path propel solution, enabling coordinated control of vehicle speed and torque across a range of applications, including wheel loaders, telehandlers, dumpers, agricultural machinery and forestry equipment. Energy optimization through adaptive ECO mode PC-PRO incorporates an all-range ECO mode that automatically adjusts engine speed at medium to high vehicle speeds. By reducing engine revolutions while maintaining constant vehicle speed, the system lowers fuel consumption and operational costs. This approach also reduces noise emissions, contributing to improved operator comfort in the cab and reduced environmental impact in work areas. Coordinated control for power and precision The software integrates advanced control functions such as auto-inch and external engine RPM request. When additional hydraulic demand is generated by work functions or steering, the system increases engine speed to maintain performance. At the same time, auto-inch adjusts hydrostatic pump output to ensure smooth vehicle movement without abrupt changes in speed. This coordinated control strategy allows machines to deliver both high power output and precise maneuverability, particularly in applications requiring simultaneous driving and work function operation. Simplified calibration and consistent performance PC-PRO includes smart calibration routines designed to reduce setup time and improve consistency across machines. Automated calibration compensates for component variations, such as differences in pump and motor response, ensuring repeatable driving behavior within a fleet. These routines reduce the need for manual adjustments during assembly and commissioning, enabling faster deployment and easier parameter transfer between machines. Compatibility and system integration The software supports multiple displacement control types, including electric displacement control (EDC), non-feedback proportional electric control (NFPE) and Hybrid Load Control (HLC). It is available on the Danfoss PC036 controller, with support for the PC062 controller planned. PC-PRO can be configured using the PLUS+1 service tool, allowing customization for specific machine requirements. It is compatible with Danfoss hydrostatic components, including MP1P and H1P pumps, H1B proportional motors and optional pressure sensors. In addition to new features, the software integrates existing functions from the PC-GO platform, such as overspeed protection, anti-stall control, load limiting and temperature management, as well as operator-focused features like cruise control and deceleration assistance. By combining advanced control algorithms, energy optimization and simplified calibration, PC-PRO addresses key requirements for modern off-highway machines, where efficiency, precision and ease of integration are critical.
