Product Details

1336‑B003‑EAD‑FA2 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 FA2 local human‑interface HIM panel, without L‑series digital I/O expansion option.

The FA2 HIM supports local on‑unit operation: physical start/stop push‑buttons, analog speed‑setting potentiometer, running/fault LED‑status indication. Operators can view basic drive parameters locally without external HIM accessories. The drive retains standard onboard base I/O terminals, but does not add extra expanded I/O channels from L‑option modules.

Internal hardware integrates 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 via external option adapters.

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 and complete motor auto‑tuning, confirm FA2 HIM panel 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 panel operation, without demand for extra expanded digital I/O.

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