Performance Parameters The drive maintains the SERVOSTAR CD family’s 800 Hz speed loop bandwidth and 3-5 kHz current loop bandwidth performance. The higher voltage capability allows the drive to achieve higher motor speeds while maintaining torque output, improving machine productivity. The PWM frequency of 8 kHz provides smooth current waveform with minimal motor heating. Position loop update rates are configurable up to 16 kHz for ultra-precise positioning applications.
Material Composition The drive enclosure utilizes aluminum alloy with powder-coated finish for durability and corrosion resistance. Internal power modules feature IGBT semiconductors mounted on ceramic substrates for excellent thermal conductivity and electrical isolation. The PCB employs high-Tg FR-4 material with heavy copper traces for power handling. Connectors are industrial-grade with gold-plated contacts. The heat sink is designed with optimized fin density for effective heat dissipation in cabinet installations.
