RS-232 Port: DB9, Connect Programmer / Host Computer Core function

Drive main control core: AutoMax system central control unit, controlling GV3000 and other frequency converters.

Multi-axis synchronous control: Single card 8-axis speed/position closed-loop, supporting multi-motor synchronization and tension control.

Independent program execution: Equipped with CPU/memory, capable of executing control logic independently without relying on the host computer.

Enhanced anti-interference and wide temperature range: E version strengthens EMC, superior high-temperature stability to C/D versions, suitable for harsh working conditions.

Hot-swappable: Replaceable in the rack while powered on, without interrupting system operation.

Version comparison (C/D/E/F/H)

0-57406-C: 0-50°C, basic anti-interference, first generation

0-57406-D: 0-55°C, enhanced heat dissipation/anti-interference, replacement for C

0-57406-E: 0-60°C, wide temperature range + strengthened EMC, mainstream replacement

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, frequency converter cluster control, high-speed production line, tension control (E version preferred in high-temperature/high-interference scenarios)

Installation and maintenance Installation

Disconnect the power supply, insert the rack slot, lock the panel; connect the RS-232 programming cable.

Power on: The OK light is on, the digital tube shows 00, which indicates normal operation. The CPU automatically recognizes.

Maintenance

Quarterly: Check the terminals, LED / digital tube, communication cables.

Half-yearly: Disconnect the power supply, perform anti-static cleaning of the panel and slots.

Replacement: E can directly replace C/D; F/H can directly replace E, without the need to modify the program / wiring.
