Product Brief:

1336‑B005‑EAD‑S1 is factory‑optioned NEMA‑1 IP20 enclosed 5‑HP 460V 1336‑PLUS full drive unit, not separate PCB boards. Derived from base model 1336‑B005‑EAD with factory fitted S1 SCANport serial communication board, without FA2 local HIM panel.

S1 board provides RS‑485 SCANport communication interface for connection to Allen‑Bradley PLC or host controller. It implements remote control, speed setting, parameter access and fault uploading for centralized automation system. External HIM device is mandatory for on‑site parameter configuration and manual operation.

Internal hardware includes rectifier power stack, IGBT inverter section, main control CPU board, auxiliary power supply and signal sampling‑conditioning circuits. Retains onboard base analog/digital hard‑wired I/O terminals for hard‑wired control.

Full protections: over‑current, over‑voltage, under‑voltage, over‑temperature, input phase‑loss, motor thermal overload, ground‑fault protection. When performing full‑unit replacement, backup original parameters, check firmware compatibility and run motor auto‑tuning. ESD protection required for installation and commissioning. Use shielded cables for communication wiring, separate power and signal cables.

Commonly used for overhaul of legacy fans, pumps, conveyors and workshop process machinery which relies on PLC network remote control, local operation depends on external HIM hardware.
