YD581 Centrifuge & Filtration VFD 1.5–160 kW
The YD581 is a dedicated variable frequency drive (VFD) for centrifuges and filtration equipment, rated 1.5–160 kW at 380 V three-phase. It provides V/f and SVC control, a common DC bus for multi-unit coordination and a master-slave differential-speed algorithm.

Product Description
The YD581 is built for centrifuges and filtration equipment, where two or more motors often run at a controlled speed difference. Rated 1.5–160 kW at 380 V three-phase, it runs V/f and open-loop vector (SVC) control with an LCD keypad.
Its defining features are a common DC bus connection, which lets units share regenerated energy, and a master-slave differential-speed algorithm that keeps the centrifuge and conveyor at the exact ratio the process needs. RS485, PROFINET, PROFIBUS-DP, EtherCAT and CANopen networking integrate the drive with plant control.

FAQ about YD581
What does the master-slave differential-speed algorithm do?
It keeps two motors — typically the centrifuge bowl and the scroll conveyor — at a controlled speed difference so the separation process stays stable. Tell us the machine type and speed ratio and we preset the parameters.
Why is a common DC bus useful?
In centrifuge duty one motor often regenerates while the other drives, so a common DC bus shares that energy between units instead of burning it in a brake resistor, cutting energy use and heat.
Which networks can I connect?
The YD581 supports RS485, PROFINET, PROFIBUS-DP, EtherCAT and CANopen. Choose the interface your PLC uses and we configure it at the factory.
