Replacement analysis

Original: 1336F-BRF50-AA-EN (1336 PLUS II 480V drive (B-frame))
Replacement: PowerFlex 753 family (OEM); PowerFlex 525 (Tier B alt for <=30HP)

Relationship: Modern platform migration (not a swap) MEDIUM

Migration / engineering work required — not a drop-in. This is not presented as a drop-in replacement.

Analyst note: Family-level OEM evidence only; 525-vs-753 multi-candidate (different migration needs) near stop condition.

What changes?

Footprint / mountingVerify 1336 frame against the PowerFlex candidate frame; mounting differs.
WiringControl wiring TB2/TB3 maps to PowerFlex I/O; 2-wire vs 3-wire input mode must be verified.
I/OAnalog scaling must be re-done; a single relay on the 525 vs multiple outputs changes interlock wiring.
SoftwareDriveTools gives way to Connected Components Workbench; parameters are re-entered, not transferred.
AccessoriesHIM modules and cables change; line protection must be re-checked per candidate.
