Industry-leading Apogee & Kepler PWM servo drives
The most demanding semiconductor applications require actuators equipped with servo drives that deliver fast, linear output with minimal distortion. Traditionally, this performance required linear amplifiers. However, advancements in technology have significantly reduced switching noise, enabling PWM servo drives to achieve high-end performance with enhanced efficiency and lower thermal loads.
Our Apogee & Kepler drives are industry leaders, offering maximum performance to achieve high precision, fast, and constant velocity with minimal jitter. They feature excellent linearity, up to 24-bit current sensing resolution (for Apogee) for accurate feedback, and ultra-low noise outputs with very low current ripple and jitter. Internal output and EMI filtering allow the drives to operate with minimal external components.
Both are PWM drives with an unrivaled filtered 200 kHz switching frequency for single- and three-phase motors. Performance once exclusive to linear drives is now achievable with PWM drives due to negligible switching noise, delivering linear-level output.
The drives can be part of a synchronized EtherCAT® network as SubDevices, with dual-loop feedback (for motor and load position) and support for incremental, analog, digital Hall, and absolute encoders. They work with any motor types, including brushless, brushed, linear, and voice coil motors. A dedicated Ethernet port with a high update/data rate (400 kHz) maximizes diagnostic capabilities.
All our drives are equipped with our versatile PMP® (Prodrive Motion Platform), which offers powerful real-time control for centralized, distributed, and hybrid systems, ensuring fast and effortless commissioning and debugging. When paired with one of our multi-axis controllers, they interface with MATLAB® and Simulink® to apply custom control-loop models optimized for any application.
