Module Feature

SIEB & MEYER 0362141EC belongs to SD2S series rack plug-in high-frequency spindle servo drive. It is designed to drive high-speed synchronous spindle motors equipped with encoder feedback. It supports ultra-high output frequency up to thousands of Hz, features fast dynamic response and precise speed & spindle orientation regulation. Built-in multi-channel voltage, current and temperature monitoring protection circuit. Compact rack plug-in structure with excellent EMC and vibration resistance 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 to form stable DC bus. Internal IGBT power stack converts DC bus into adjustable high-frequency three-phase AC power to drive spindle motor. The drive continuously collects real-time encoder speed and position feedback signal to execute closed-loop control. When overvoltage, overcurrent or overtemperature fault is detected, the drive immediately cuts off power output and sends fault code to upper rack control 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.
