SIEB & MEYER 0369810DF4100 Spindle Servo Amplifier

Module Feature

SIEB & MEYER 0369810DF4100 belongs to SD2M series high-frequency spindle servo amplifier. It is designed to drive high-speed synchronous spindle motors equipped with multi-type encoder feedback including resolver, Sin/Cos and EnDat. It supports ultra-high output frequency, fast dynamic response and stable speed & spindle orientation regulation. Built-in multi-channel voltage, current and temperature monitoring protection circuit. Compact rack plug-in metal housing with excellent EMC and anti-vibration performance. Widely used in PCB routing, semiconductor drilling and CNC milling machines.

Working principle

Three-phase AC input power passes EMI filter and rectifier bridge and converts into stable DC bus. Internal IGBT power stack converts DC bus into adjustable high-frequency three-phase AC power to drive spindle motor. The amplifier continuously collects real-time encoder speed and position feedback signal to execute closed-loop speed and spindle orientation control. When overvoltage, overcurrent or overtemperature fault detected, the amplifier immediately cuts power output and sends fault code to upper rack CNC system for safety interlock.

Onboard components

IGBT power stack, DC-link capacitor bank, current & voltage sampling circuit, encoder signal conditioning interface, main control processor, temperature sensor, power terminal block, gold finger backplane connector, LED status indicator array.

LED indicators

Front panel LED indicators for module power, drive ready, spindle enable, running status and fault code display.

Hardware self-diagnosis

Visual inspection of module housing, terminals and backplane gold fingers; DC bus voltage measurement; spindle motor cable insulation and continuity test; read LED fault codes; inspect cooling fan and heat sink for dust accumulation or damage.

Programming software

SIEB & MEYER Drivemaster2 commissioning software for spindle parameter configuration, auto-tuning and firmware inspection.
