2. Model Number Definition

• 0-: Standard Reliance Electric prefix

• 57552: Core model = Universal Drive Controller (UDC)

• 4: Hardware revision (4th version)

• B: Firmware/functional revision (B-level update, enhanced vs. 4A)

3. Technical Specifications

4. Interfaces & Communication

Communication Ports

• Fiber Optic Links ×2: To 2 PMIs; control/diagnostic data (high noise immunity)

• Multibus Backplane: Slave communication to AutoMax CPU

I/O Interfaces

• Analog Outputs ×4: Data logging/external meters

• Status LEDs ×6: PWR, RUN, COMM A/B OK, DRV A/B FLT

5. Core Functions

1. Multi-Axis Motion Control: Speed/position/torque control; synchronous motion

2. Real-Time Processing: Onboard PID loops; closed-loop regulation

3. Fault Protection: Over-current/over-voltage/over-temperature monitoring; alarm/log

4. Programmable: Configurable via AutoMax software (Manual S-3007)

5. Data Monitoring: Analog + fiber optic comms; real-time data upload

6. Application Scenarios

• Automotive assembly lines

• Electronics & packaging machinery

• CNC machine tools (lathes, mills)

• Metallurgy, paper, textile, chemical processing

• Large machinery with multi-motor coordination

7. Usage & Maintenance

Installation

• Mount in AutoMax standard rack (single slot); secure backplane connection

• Keep fiber connectors clean; shield/ground analog wiring

Programming

• Use AutoMax Programming Software (S-3007)

• Configure drive parameters, control mode, and communication addresses

Maintenance

• Check LED status regularly; troubleshoot fiber links/PMI/power on faults

• Maintain rack ventilation (0–55°C); avoid dust/humidity

• Power up spares periodically to preserve Flash data

4B vs. 4A

• 4B: B-rev firmware, enhanced diagnostics and compatibility with later AutoMax racks/PMIs; otherwise identical to 4A.
