Technical Specifications

Input Power：3Φ AC400~480V ±10% 50/60Hz; isolated single-phase AC230V auxiliary control supply

Nominal DC Bus：700VDC

Output Rating：Continuous 200A RMS; 250% overload sustain 300ms, 300% instantaneous peak overload; max output frequency 1600Hz, match approx 62kW Indramat 2AD/ADF/1MB spindle motor; default PWM 4kHz, optional 8kHz with current derate

Brake Configuration：Zero internal bleeder, external high-power braking resistor required for all deceleration & regenerative operation

Cooling：Integrated front blower, total power loss ~1370W

Protection Grade：IP20 (EN60529), vertical cabinet mounting only

Ambient Condition：0~+45℃ full-load operation, automatic output derate over 45℃; storage -30~+85℃; altitude ≤1000m; RH＜90% non-condensing

Dimension & Net Weight：H822×W350×D353mm, approx 50.2kg

Compatible Motors：Indramat 1MB,2AD,ADF,LAF,LSF series AC spindle & synchronous servo motors

Interface & Communication Configuration

Main Power Terminals：Heavy-duty L1/L2/L3 three-phase mains input, U/V/W high-current motor output terminals

Command Interface：Dual SERCOS fiber optic ports (IN/OUT daisy-chain multi-axis bus), no ±10V analog command terminal

Feedback Connector：1×15Pin D-SUB port, support resolver or single-channel TTL incremental encoder feedback

Onboard IO：Fixed 8DI/5DO standard digital terminal block, no reserved U2/U3 expansion slots（distinguish from high-grade BE23/BE48）

Debug Port：Front panel RS232 serial port (9600/19200 baud) for IndraWorks parameter setup, fault diagnosis & data backup

Auxiliary Terminal：Drive enable, hardware E-stop, motor PTC thermal detection, fault relay dry contact, drive ready status signal terminals

DSM Card Slot：Front empty memory card slot for non-FW version, no factory pre-installed firmware card

Core Functions

Current-speed-position triple closed-loop digital control via SERCOS bus; BE11 baseline function：spindle constant speed control, C-axis basic rotary positioning, rigid tapping; no electronic cam & advanced electronic gear synchronization（reserved on BE23/BE48 high-end board）; full protection: overcurrent, DC bus over/undervoltage, IGBT overheat, fan malfunction, feedback wire break, front LED digital fault code display; non-FW blank slot unit cannot run directly after power-on, must equip matching programmed DSM card and download dedicated ESM03 firmware via IndraWorks。

Application Fields

Standard CNC machining center SERCOS bus spindle, conventional CNC lathe digital spindle, printing single-axis winding equipment, old analog CNC upgrade to digital SERCOS control system.

Operation & Maintenance Instructions

Only connect three-phase AC400~480V industrial power, single-phase input triggers DC bus undervoltage lockout with zero output.

Reserve ≥90mm upper/lower cabinet ventilation gap to avoid blower insufficient cooling leading to overheat shutdown & output derating.

N-type no internal bleeder structure: external matched braking resistor must be configured regardless of continuous or intermittent stopping working mode.

BE11 SERCOS mainboard cannot cross replace with BA analog control board or high-spec BE23/BE48 board directly, function mismatch causes abnormal axis motion.

Non-FW empty slot model: preserve original DSM parameter backup during maintenance; replacement DSM needs full parameter re-download via IndraWorks software.
