What the G5-Series means for fit
The G5-Series is Omron's earlier generation of compact servo drives, typically paired with matching G5 motors and encoders. If the original machine design used a G5 drive, the R88D-KN02H-ML2 is the direct drop-in — but the EOL status means any replacement should be evaluated against the current G5-series successor or a cross-platform alternative before a last-time buy.
