FAQs
Yes. The ACS310-based module is designed for LV installations and aligns with ABB motor families and common control panels. When retrofitting, verify motor rating (0.75 kW, 4.7 A) and ensure correct wiring of supply, motor, and signal inputs. Use ABB parameter libraries to minimize setup time and preserve control accuracy in pumps and fans.
Key specs include a 0.75 kW power rating and 4.7 A nominal current, with built-in PID controllers and dedicated pump/fan control (PFC). PID control shines in systems with changing flow or pressure, such as booster pumps and supply/return fans, delivering tighter regulation, reduced energy use, and smoother operation.
Best suited for pump and fan-driven processes where speed needs to respond to process data. Typical use cases include booster pumping stations, HVAC systems, and process cooling loops. The compact LV drive form factor and ACS310 compatibility support both new installations and retrofits, enabling energy savings and performance consistency.
Look for CE marking for safety and EMC compliance, SIL considerations for safety-critical control applications, and appropriate IP enclosure ratings for protection in harsh environments. While this document notes these standards as important, confirm the exact certifications for your regional requirements and the specific deployment environment.
The built-in diagnostics and protection reduce downtime and simplify preventive maintenance. Energy savings from variable-speed control lower operating costs over time, while the robust PID-based control improves process stability, reducing wear on pumps and fans. Retrofit projects typically realize faster payback through lower energy consumption and improved reliability.
