E104876 - Regenerative Resistance PCB Assy

E104876 – Regenerative resistance board (Regenerative Resistance PCB) – Mimaki JV33/CJV30

The E104876 regenerative resistance board (Regenerative Resistance PCB Assy) is part of the motor drive circuit of Mimaki JV33 and CJV30 printers.

During the deceleration phases of the axis motors (X and Y), they generate a back-EMF (regenerative braking energy). This board dissipates that energy as heat through its power resistors, protecting the motor drivers and the on-board electronics against over-voltage. A failing board can cause emergency stops, motor driver errors or damage to the electronics.
