Working Principle
Three-phase 204–480 VAC mains power enters the internal rectifier circuit, converted to smooth DC bus voltage for IGBT power inversion stage. Onboard motion control MCU receives position, speed and torque command signals via fieldbus communication from upper machine controller, generates PWM drive waveforms to control IGBT switching and output three-phase variable frequency AC power to servo motor. Encoder feedback signals from motor are sampled at 62.5 μs fixed cycle, MCU calculates position deviation and executes PID closed-loop correction to realize high-precision motion control. All hardware protection circuits continuously monitor bus voltage, output current and drive internal temperature; protection triggers immediately with drive output shut-off if threshold exceeded.
Application Scenarios
- Heavy-duty metal forming machinery, hydraulic servo press equipment OEM integration
- Automated warehouse heavy-load stacker cranes, port container handling auxiliary axes
- Large textile printing and dyeing production line main drive servo systems
- Woodworking CNC routing machines, stone cutting heavy load positioning equipment
Installation Requirements
- Directly embedded mount inside OEM machine mechanical frame via four corner mounting holes; maintain minimum 30 mm clearance around aluminum heat sink fins for air convection cooling
- Power cable cross-section minimum 2.5 mm² copper wire, all power terminals tightened to specified torque value to avoid overheating
- IP65 front panel must install with full compression of rubber gasket to maintain dust/water protection grade; gasket damage invalidates IP rating
- Fieldbus communication cables use M12 shielded industrial cables, maximum bus cable length limited to 100 meters
- Machine frame PE grounding connection mandatory with ground wire cross-section ≥4 mm²
Operation & Maintenance Precautions
- Power drive unit must fully discharge DC bus residual voltage (minimum 10 minutes) before disassembly wiring maintenance
- Do not operate drive continuously above 60 °C ambient temperature without auxiliary forced air cooling
- Avoid direct high-pressure water washing on drive housing even with IP65 rating; only low-pressure dry compressed air cleaning permitted
- Motion program and drive parameters configured exclusively via Jetter JetSoft programming software
- Replace internal cooling fan every 30,000 operating hours to prevent overheat protection shutdown
