SIEB & MEYER 03631490IC00A0 Spindle Servo Amplifier

Module Feature

SIEB & MEYER part number 03631490IC00A0 B0 belongs to SD3 series standalone high-frequency spindle servo amplifier. It is designed to drive high-speed synchronous spindle motors with multi-type encoder feedback. It supports ultra-high output frequency for ultra-high spindle rotational speed, features fast dynamic response and stable speed & spindle orientation regulation. Built-in multi-channel voltage, current and temperature monitoring protection circuit. Compact standalone metal housing 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 speed and spindle orientation control. When overvoltage, overcurrent or overtemperature fault is detected, the drive immediately cuts off power output and sends fault code to upper CNC 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, external signal connectors, LED status indicator array.

LED indicators
