Product Details

1336‑B003‑EAD‑FA2‑L1 is factory‑optioned complete NEMA‑1 enclosed 3‑HP 460V 1336‑PLUS AC drive, not separate PCB boards. Based on base model 1336‑B003‑EAD, factory pre‑installed two key options: FA2 local human‑interface HIM panel and L1 digital logic I/O expansion interface module.

The FA2 HIM provides local on‑unit operation: physical start/stop push‑buttons, analog speed potentiometer, running/fault LED status indication, allows local parameter viewing without external HIM accessories. The L1 option adds expanded discrete digital logic input/output channels for additional interlock, status feedback and peripheral device linkage requirements.

Internal hardware includes rectifier power stack, inverter IGBT power section, main control CPU board, auxiliary power supply, sampling and signal‑conditioning circuits. Supports sensorless vector and V/F control for standard three‑phase induction motors. Accepts external analog speed reference, discrete start‑stop interlock signals, supports SCANport communication expansion.

Full protection suite: over‑current, over‑voltage, under‑voltage, over‑temperature, input phase‑loss, motor thermal overload, ground‑fault protection. Used for full‑unit replacement when multiple internal assemblies suffer compound damage. When swapping complete drive, back‑up original parameters, verify firmware compatibility, complete motor auto‑tuning, and confirm FA2 / L1 option function matching. Strict ESD protection required for installation and commissioning.

Typically applied for overhaul of legacy fans, pumps, conveyors and general‑purpose processing equipment requiring local operator control plus extra digital I/O interlock.

Remark:Legacy EOL complete drive unit;original production discontinued;please confirm motor rating, input voltage, installation dimension and option function matching before purchase.
