4.8 HPCU Parallel Control Module
The HPCU parallel control module serves to receive drive and control signals sent
from the HCU through communication and transmits such signals to each AC drive
synchronously, acting as an intermediary in the system. Meanwhile, it uploads the
current, voltage, and status data sent from the AC drive to the HCU and controls
synchronization, current sharing, reset, and start/stop operations of AC drives
connected in parallel.
Depending on system requirements, HPCU-40 (four parallel modules) or HPCU-60 (six
parallel modules) can be selected.
