Product Description:
The PRD-0040SNIC-C2 Servo Amplifier provides motion control for industrial motors. It supports precise position and current control using integrated feedback systems. The model is designed for compatibility with resolver based feedback.
The PRD-0040SNIC-C2 servo amplifier from Kollmorgen features dual control loops for precise motion regulation. The position loop operates at an update rate of 500 μs (2 kHz) that enables accurate shaft positioning. The current loop runs significantly faster with a 62.5 μs (16 kHz) update rate and bandwidth below 2000 Hz. This provides stable and responsive current regulation. Resolver feedback is supported by the amplifier with a transformer based system using sinewave reference signals. It accepts input voltage of 4.25 Vac and provides 2 Vac output to the drive. The resolver operates at a modulation frequency of 7 – 8 kHz with a transformation ratio of 0.47. It supports a maximum drive current of 55 mA ac-rms and a maximum DC resistance of 120 Ohms. The servo amplifier calculates velocity from position change and enhances resolution up to 16 bit for position and 18 bit for velocity feedback through patented techniques.
The PRD-0040SNIC-C2 servo amplifier from the CD Servostar series uses a Resolver to Digital Converter with adaptive digital resolution based on velocity limit (VLIM) in terms of feedback processing. This ensures optimal velocity control performance. The system is designed to handle both single and multi speed resolver configurations. The low level sine and cosine signals used in the resolver feedback system are sensitive to noise and the amplifier is built to manage this susceptibility with stable signal handling. The high update rates in the control loops enhance motion smoothness and reduce response latency. The precise bandwidth control in the current loop minimizes signal distortion and improves current regulation under dynamic load conditions.
