Product Introduction of Corresponding DIAX04 Drive System

DIAX04 is modular shared DC-bus digital multi-axis servo amplifier from Indramat, split into HDS (power supply module) + HDD (single-axis servo power module) + ELS standalone single drive, matching MDD/MKD/MHD synchronous servo motors, widely used on old CNC, packaging, printing production equipment.

Core Electrical Parameters of DIAX04 Hardware

Main Input: 3-phase AC 200~480V 50/60Hz, HDS as central rectifier to supply shared DC bus for all HDD axis modules

Output Current Range: HDD series continuous 10A~100A; ELS small drive 2A~30A; W=cooling with built-in fan, N=naturally cooled without fan

PWM Frequency: Fixed 8kHz carrier frequency for all series modules

Ambient Spec: Operation 0~+45℃, storage -20~+70℃, cabinet mounting IP20, non-condensing environment

Discharge Rule: Power down wait minimum 5min for internal capacitor full discharge before maintenance

Interface & Communication Configuration

Power Interfaces

X5 terminal block: DC bus connection between HDS-HDD, U/V/W motor three-phase output, brake wiring terminal; X1: adjacent module internal bus stacking port for multi-axis rack assembly

Feedback Port

DB15 dedicated encoder connector, support TTL incremental encoder, optional resolver feedback via option card

Control Bus

Standard SERCOS fiber bus as primary digital motion control; optional ±10V analog speed/position command for external PLC control

Digital I/O Terminal

24VDC discrete terminals: drive enable, emergency stop, positive/negative limit input, fault relay dry contact output

Front Panel Interface

7-segment LED fault code display, local parameter setting buttons, service debug port

Core Functions

Full digital current-speed-position triple closed-loop control, built-in auto motor identification & auto-tuning routine

Multiple operation modes: SERCOS bus positioning, analog velocity/position control, front panel local jog mode

Complete protection: overcurrent, over/under voltage, overheat, encoder loss, output short-circuit, stall protection with unique F-series fault code definition

Modular DC-bus energy sharing, internal dynamic brake circuit, external braking resistor only required for high inertia heavy load

Electric gear synchronization function for multi-axis electronic cam & synchronous winding applications (ELS dedicated function)

All drive parameters saved in onboard nonvolatile memory, no extra memory card needed
