Working Principle: Three-phase AC power enters the drive and converts to stable DC bus voltage via internal rectifier. The power IGBT bridge converts DC bus into variable frequency three-phase AC to drive servo motor. The drive samples motor encoder feedback signal continuously, compares feedback value with motion command. Internal control algorithm calculates error and adjusts output current to achieve closed-loop position, speed or torque regulation. STO safety circuit directly disables power stage gate drive signals to remove motor torque when safety signal triggers. EtherCAT bus receives motion commands from master controller and transmits axis status and fault data back in real time.
Installation Requirements:
- Mount drive vertically on cabinet internal metal backplate
- Maintain sufficient clearance around heat sink for natural convection cooling
- Use shielded high-current servo cable for motor wiring
