Debug Port：Front RS232 serial for IndraWorks parameter download, diagnosis and firmware upgrade, preloaded standard FW basic firmware

Core Functions

Full three-loop closed-loop control(position/speed/torque), full set of machine tool spindle exclusive functions: rigid tapping, C-axis spindle indexing/orientation, constant-power wide speed regulation. Internal B-type bleeder realizes fast dynamic braking under emergency stop and power drop, superior deceleration performance vs grid-regen N-type. Complete fault protection: overcurrent, DC bus over/undervoltage, IGBT overtemperature, feedback wire break, LED fault code indication; BE23 hardware reserves electronic cam and master-slave synchronous function expansion space.

Application Fields

Heavy vertical/horizontal machining center main spindle, large gravure rotary printing press, heavy textile high-speed winding spindle, large linear servo automation, hot forging forming main transmission equipment.

Operation & Maintenance Instructions

Strictly connect three-phase 400~480V AC industrial power; single-phase 220V input triggers persistent DC bus undervoltage alarm with no full torque output.

Reserve ≥160mm top & bottom cabinet ventilation clearance to guarantee blower airflow and avoid over-temperature derating/shutdown.

Frequent high-inertia emergency stop can use built-in bleeder; only ultra-heavy cyclic braking needs extra high-power external bleeder resistor matching.

Parameter tuning requires IndraWorks software matching built-in FW firmware; parameters not interchangeable with BA analog interface or other BExx code variants(BE12/BE33 etc.).
