Functional Features
- Independent motion task execution apart from main CPU
- Speed, position, and torque control
- Dual-port RAM for deterministic data exchange
- Supports closed-loop and open-loop modes
Application Scenarios
Motor control in Reliance-driven crane, conveyor, winder, and machine-tool systems retaining AutoMax architecture.
Structural Characteristics
AutoMax slot module with dual-port memory chips, flash, front LEDs, and backplane/fiber interfaces. No user-accessible switches.
Working Principle
The AutoMax CPU downloads motion setpoints into dual-port RAM; the 57C552-1’s onboard logic closes the loop with the drive via fiber or serial link and returns actuals to the CPU map.
Installation Requirements
Insert in a spare AutoMax processor-class slot with backplane power. Connect fiber or drive comms cable to the target drive terminal.
Usage Precautions
Confirm drive firmware compatibility. Do not mix 57C552 revisions without checking AutoMax BIOS/loader support. Avoid static discharge when handling the board.
