LDU II
The LDU II from Okuma offers rotor speeds of 100–600 rpm and uses a 380V AC 50Hz (≤10KVA) supply. Part of the BL Servo Drives series, it supports high-purity N2 and Ar gases with degassing efficiency ≥35%. The card uses 100μF, 680μF and 1500μF capacitors and regulates 24V and 5V DC outputs.
It features a Xilinx Spartan XC2S50-5PQ208 FPGA, a BL3D (201D) motion controller and inductive power filtering. The launder shell temperature stays ≤60°C. It ensures a lining life ≥12 months.
