ACS UDI
ACS UDI
ACS UDI is an EtherCAT interface for commanding external motor drives through analog signals; it is not the motor power amplifier. The HP/LT family supports up to four drivers, and a historical sold UDIhp4400N01S listing provides a US$219.99 used-price reference.
Review Summary
UDI is worth evaluating when an ACS control system needs to retain external amplifiers with a compatible analog command interface. The important purchasing distinction is between commanding a drive and powering a motor: UDI performs the interface role, while the external amplifier provides the motor power stage. A low-priced module therefore does not represent the total cost of an axis.
