0-57406C
Description
Model Explanation 0-57406-C
0-57406: Basic model (AutoMax drive control core)
C: First-generation hardware revision (followed by D/E/F/H upgrades)
Full name: Drive Controller Module
Compatibility: AutoMax PLC / DCS 5000 rack; can be directly replaced by D/E/F/H, reverse compatibility requires program confirmation.
Technical parameters (official)
Manufacturer: Reliance Electric (now Rockwell Automation)
Processor: Intel 80186 16-bit CPU, with hardware watchdog
Number of control axes: Up to 8 axes (with I/O module expansion)
Memory: 128KB RAM / 256KB EPROM
Communication: RS-232 (DB9, programming / debugging), AutoMax backplane bus
Operating temperature: 0°C ~ +50°C (C version minimum, D/E/F/H gradually relaxed)
Isolation: 2500 VAC photoelectric isolation between backplane and control circuit
Size: 343 × 203 × 38 mm (standard 1.25" slot)
Weight: Approximately 0.9 kg
Power consumption: ≤18 W
Protection: IP20
Interfaces and indicators
Backplane: Special edge connectors (power, address, high-speed data)
Front panel:
2-digit digital display: shows fault codes (e.g. 00 = normal)
OK (green): module running normally
FAULT (red): CPU / program / communication failure
TEST switch: 3 positions (self-check / operation / debugging)
RESET button: hardware reset
RS-232 port: DB9, connects programmer / upper computer
Core function
Drive Control Core: The central control unit of the AutoMax system, directly managing the GV3000 and other inverters.
Multi-axis Synchronization Control: Up to 8 axes of speed/position closed-loop per card, supporting multi-motor synchronization and tension control.
Independent Program Execution: Equipped with its own CPU and memory, capable of independently executing drive control logic without relying on the host computer.
Basic Fault Diagnosis: Digital display shows specific fault codes, quickly locating CPU, communication or program errors.
Hot Swap: Replaceable in the rack while powered on, without interrupting system operation.
Version Comparison (C vs D/E/F/H)
0-57406-C: 0-50°C, basic anti-interference, first-generation version
0-57406-D: 0-55°C, enhanced heat dissipation / anti-interference, replacement for C
0-57406-E: 0-60°C, wide temperature + enhanced EMC, mainstream replacement version
0-57406-F/H: 0-60°C, full functionality + highest stability, final version
Typical Applications
System: Reliance AutoMax / DCS 5000
Industry: Metallurgy, Papermaking, Water Treatment, Power, Heavy Machinery
Purpose: Multi-motor synchronization, inverter cluster control, high-speed production line, tension control
Installation and Maintenance Installation
Disconnect the power supply, insert the rack slot, lock the panel; connect the RS-232 programming cable.
After powering on, the OK light will be on and the digital display will show 00, indicating normal operation. The CPU will automatically identify. Maintenance
Quarterly: Check terminal fastening, status of LED / digital tube, communication cables.
Half-yearly: Power off and perform static electricity prevention cleaning of the panel and slots.
Replacement: D/E/F/H can be directly replaced with C; no need to modify the program / wiring; reverse replacement requires testing compatibility.
