Option codes +E202, +J400, +K458 — what they signal
The ACS850-04-202A-5+E202+J400+K458: The suffix +E202, +J400, +K458 are ABB configuration option codes. +E202 typically denotes a specific I/O extension or fieldbus adapter; +J400 often relates to a control panel or keypad variant; +K458 may indicate a braking chopper or output filter option. Without the ABB configuration decoder, the exact function is not confirmed here, but these codes tie the drive to a particular order-time specification — a replacement unit must match them to preserve the installed wiring and parameter set.
