ALLEN BRADLEY 322912-A02 S/N:4007404829

Overview

ALLEN BRADLEY 322912-A02, serial trace code 4007404829, is a fiber optic communication board for the Allen‑Bradley PowerFlex 700S synchronous transfer drive series. It is a dedicated high-speed optical interface board used for SynchLink fiber communication between multiple PowerFlex 700S drives, enabling precise synchronized shaft control for winders, paper machines and coordinated multi-axis systems. It is widely supplied as exchange spare for large process drive cabinets and synchronized motion control panel overhaul and replacement.

Features

ALLEN BRADLEY 322912-A02 uses optical fiber transmission to distribute a shared high‑speed sync clock and torque reference signal across the drive group. The fiber medium eliminates common-mode noise and ground loop interference in high‑power SCR/IGBT drive cabinets. It supports tight synchronization of output frequency, phase and torque between multiple 700S drives, which is critical for winder tension control and line shaft applications.

ALLEN BRADLEY 322912-A02 works as an internal daughter board fitted onto the main control cassette of PowerFlex 700S. Onboard LED indicators display optical link status, sync activity and fault flags for quick on-site troubleshooting. It supports ring or daisy-chain SynchLink topology and includes loss-of-light and frame error detection. Configuration and synchronization tuning are completed via DriveTools SP software. It is designed for open-frame cabinet installation and conforms to industrial EMC standards.

Specs

ALLEN BRADLEY 322912-A02Platform: Allen‑Bradley PowerFlex 700S drive system Type: SynchLink fiber optic communication daughter board Part number: 322912-A02 Serial number: 4007404829 Protocol: SynchLink high-speed synchronous link Media: optical fiber Function: multi-drive clock sync, torque reference distribution Compatible drive: PowerFlex 700S Phase II Mounting: plug-in onto 700S control cassette Protection rating: IP20 This is not a main control board, power board or PLC; it is the dedicated SynchLink fiber expansion board for synchronized drive groups. ALLEN BRADLEY 322912-A02 is widely supplied as service replacement spare for multi-drive synchronous communication failure.

Principle

ALLEN BRADLEY 322912-A02 receives the master sync frame from the primary drive over fiber. The board recovers the high precision clock and shared torque setpoint, then forwards the sync frame to the next drive in the chain. Each slave drive aligns its PWM cycle and control loop timing to the master clock. If a fiber break, signal loss or sync frame error occurs, the board reports a fault and the drive executes a coordinated stop sequence to protect the process.

Applications

ALLEN BRADLEY 322912-A02 is deployed for paper machine section drives, plastic film winders, metal rolling lines and multi-axis web processing machinery. It is selected for spare inventory and drive cabinet retrofit projects for existing PowerFlex 700S SynchLink synchronous motion systems.
