0-57411-1

0-57411: Basic type AutoMax resolver input module

1: Version 1 (standard version, including basic functions and firmware)

Full name: Resolver Input Module for AutoMax / DCS 5000

Compatibility: Compatible with 0-57407 CPU series and standard AutoMax chassis / power supply; compatible with versions 0-57411-2/3 and others in the same series, can be directly replaced Technical Specifications

Manufacturer: Reliance Electric (now Rockwell Automation)

Function: Collect the angular position signal from the resolver, convert it to digital form, and use it to calculate the position and speed of the rotating shaft.

Input: 1 resolver input channel, with an **external strobe input** for external event synchronization.

Resolution: Single turn 12-bit; 2-bit revolution counter.

Sampling Time: 500 μs to 32.767 s (software configurable)

Excitation: Built-in resolver excitation signal (frequency/voltage adapted to standard resolver)

Isolation: Channel - backplane isolation 2500 VAC

Operating Voltage: 15 VDC (taken from the AutoMax backplane)

Operating Temperature: 0°C to +60°C

Conformal Coating: No (Rev 1 standard design)

Dimensions: 342 × 205 × 30 mm (1.25 inch slot)

Weight: Approximately 0.7–0.9 kg

Protection: IP20

Power Consumption: ≤ 12 W Front Panel & Indicators

Status LED: ISP OK, CCLK OK, FDBK OK (indicating normal communication, clock, and feedback of the module respectively)

Interface: Front terminal panel (for connecting gyroscope cables) + Backplane connector

Support hot-swappable installation / removal Key Features

12-bit high-precision position feedback: Suitable for high-precision scenarios such as servo control and spindle positioning

External synchronous selection (Strobe): Achieves precise synchronization with external events (such as encoders, PLC signals)

RPM counting (2-bit): Can record multiple circle positions, meeting requirements for long stroke / multi-circle motion control

Standard AutoMax architecture: Directly compatible with existing frames and CPUs, no need for additional adapters

High anti-interference design: Isolates 2500 VAC, suitable for industrial strong interference environments Applications

System: Reliance AutoMax / DCS 5000

Industries: Metallurgy, Papermaking, Machine Tools, Wind Power, High Precision Motion Control Field

Use: Collect servo motor / spindle rotary change signals, used for position closed-loop, speed closed-loop, spindle orientation, etc. control

Revision Notes (0-57411 Series)

0-57411-1: Rev 1, Basic Version, 0–60°C, No Coating

0-57411-2: Rev 2, PCB Optimization, Enhanced Anti-interference

0-57411-3: Rev 3, Conformal Coating (conformal coating), Suitable for Harsh Environments Installation & Maintenance

Installation: Insert into the AutoMax slot, lock the clamping mechanism, and rotate the signal connector to the front terminal plate.

Maintenance: Conduct quarterly checks on wiring tightness; clean the connectors (ESD protection) every six months.

Interchangeability: All versions of the same series can be directly interchanged without the need to modify the program.
