Variable Speed Drives

ABB HVAC DRIVES

Software Characteristics for the ACH580 HVAC Drives Family

The ACH580 drives come with a range of advanced features that not only provide a thorough heating, ventilation and air conditioning control, but also
make drive integration, commissioning, and operation easier than ever before

System overpressure protection
The interlock protects water pipes/air ducts by stopping
pump/fan operation when the measured pressure exceeds Pump dry run protection
a threshold, e.g. due to closed valves/dampers. The interlock stops operation when the pressure on the
pump suction side is below a threshold, to prevent pump
damage from running dry.

Frost protection
Cold temperatures outside might lead to heating coil
freezing. To avoid damage, drives can alarm on a too low
air temperature and shut down the system.

Sleep/boost
The feature stops the pump at low demand, instead of
running it slowly below its efficient operating range. Allows
to save energy and extend the pump and motor lifetime by
decreasing start/stop cycles during the day.
