Rexroth DKC02.3-100-7-FW EcoDrive03 High-Performance Single-Axis Servo Drive Controller

Product Description

DKC02.3-100-7-FW belongs to Rexroth Indramat EcoDrive03 DKC series, a heavy-duty high-current digital servo amplifier manufactured in GermanyIndramat U....

It adopts advanced DSP closed-loop control architecture to realize precise position, speed and torque regulation for high-power 3-phase AC synchronous servo motors. The model features 100A continuous output current with 700V nominal DC bus voltage, suitable for heavy-load CNC machine tools, automotive automation lines, large printing and metal forming equipment.

The "-7-FW" suffix stands for SERCOS fiber optic real-time communication interface with complete firmware support. It supports mainstream encoder feedback including EnDat, resolver and incremental encoders, with built-in full-range fault diagnosis and multi-layer electrical protection circuits. Standard cabinet vertical mounting design, IP20 protection, conformal coated PCB for anti-vibration and anti-humidity, widely used as core maintenance spare for multi-axis high-power motion control systems.
