Product Details

1336‑B003‑EAD‑FA2‑L2 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 and L2 enhanced mixed I/O expansion module.

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 L2 option provides enhanced mixed‑signal expansion: extra discrete digital inputs / relay outputs plus supplementary analog I/O channels. It enables multi‑speed preset selection, external process signal collection, complex interlock logic for multiple field devices, compared with basic L1 option, L2 offers richer analog‑digital combined control resources.

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 and L2 I/O option function matching. Strict ESD protection required for installation and commissioning.

Typically applied for overhaul of legacy fans, pumps, conveyors and process equipment requiring local panel operation together with complex multi‑signal interlock and analog feedback acquisition.

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