Analog instruction interface (BA05 board X2 terminal): ±10V speed instruction, ±10V torque setting, compatible with FANUC/Siemens old-fashioned analog numerical control systems

Feedback interface: Dual 15-pin D-SUB, one for rotary encoder interface, one for TTL incremental encoder interface (exclusive hardware layout for BA05)

Slot layout: U1 fixedly installs BA05 analog control board, U5 fixedly inserts FW firmware card, U2/U3/U4 reserved for I/O and encoder expansion slots

Debugging port: Front panel RS232 debugging serial port, IndraWorks software reads and writes parameters, firmware upgrade

General I/O terminals: Drive enable, hard emergency stop, motor temperature monitoring, brake linkage, fault passive relay contacts, driver ready signal output terminals Core Functions

Full digital three-loop closed-loop (position / speed / torque) spindle dedicated control, standard features include wide constant power speed regulation, C-axis indexing positioning, rigid tapping, and electronic gear synchronization function; N-type grid feedback energy saving; continuous braking conditions generate much less heat than B-type models with built-in choppers; Full-link fault protection: overcurrent, bus over/under voltage, power module overheating, encoder breakage, fan failure, panel LED fault code indication; FW firmware card has independent parameter storage, spare parts replacement can directly plug in and out the firmware to restore device parameters, without the need for re-motor identification and setting. Application Fields

Imported old vertical/horizontal machining centers' spindles, large offset rotary printing main drives, chemical fiber high-speed winding main shaft equipment, old forging forming main drives, and old equipment's CNC renovation projects. Operation & Maintenance Instructions

Only three-phase 400~480V industrial power supply is available. Single-phase input is prohibited. Single-phase power supply will continuously trigger a bus under-voltage alarm and prevent full power output.

A minimum of 90mm ventilation gap is reserved at the top and bottom of the cabinet to ensure smooth air intake and exhaust for the fan and prevent overheating from triggering power reduction and shutdown.

N-type without built-in chopper: Normal no-load deceleration relies on grid feedback. Frequent emergency stops with large inertia must be equipped with an external high-power braking resistor to avoid overvoltage trip and shutdown of the bus.

Debugging can only be performed using the IndraWorks software with the matching DSM02.3 firmware version. The BA series simulation firmware and the BE series SERCOS optical firmware cannot be mixed and used interchangeably.

On-site spare parts replacement: Directly migrate the original equipment's FW firmware card, power on and restore the original equipment parameters with one click to shorten the downtime for debugging.
