Motor Deceleration & Regenerative Braking Solution – FUJI EP-3429-C6-Z2 | FUJI Electric Brake Module Series
Where This Product Is Used
The FUJI EP-3429-C6-Z2 Brake Module is engineered for demanding industrial environments where precise, rapid motor deceleration and regenerative energy dissipation are critical. Typical deployment scenarios include:
- Overhead Crane & Hoist Systems – Provides controlled stopping force to prevent load swing and ensure operator safety during high-cycle lifting operations.
- Conveyor & Material Handling Lines – Enables smooth, repeatable deceleration on inclined or high-inertia conveyor belts, reducing mechanical wear on gearboxes and couplings.
- CNC Machining Centers & Spindle Drives – Absorbs regenerative energy during rapid axis reversals, protecting the DC bus of Fuji Electric inverters from overvoltage faults.
- Elevator & Vertical Transport – Works in tandem with Fuji FRENIC-series drives to manage counterweight imbalance energy during descent cycles.
- Extruder & Winding Machines – Maintains constant tension during emergency stops on film, wire, and textile winding applications.
- Pump & Fan Drives with Variable Load – Prevents DC bus overvoltage when load inertia exceeds drive capacity during deceleration ramps.

Application-Specific FAQ
Q: Is the EP-3429-C6-Z2 compatible with all Fuji FRENIC drives?
A: The EP-3429-C6-Z2 is designed for specific FRENIC-series models. Please provide your drive model number to our team for a definitive compatibility check before ordering.
Q: Do I need an external braking resistor with this module?
A: Yes. The brake module controls the switching of regenerative energy to an external resistor. The resistor must be sized according to Fuji Electric’s application guidelines for your specific load inertia and deceleration time requirements.
Q: Can this module be used for continuous regenerative braking duty?
A: The duty cycle depends on the thermal rating of both the brake module and the external resistor. Consult the Fuji Electric technical manual or contact our engineering support team for duty-cycle calculations.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. For out-of-stock situations, lead times vary by sourcing channel. Contact us for real-time availability.
Q: Do you provide installation support?
A: Yes. Konmask’s technical team can provide wiring diagrams, parameter settings, and commissioning guidance for Fuji Electric brake module installations.
