Product Description:

The PRD-0045000z-25 drive is intended for precision position drives where rapid signal processing is required. The drive supports up to 3 MHz input frequency before quadrature and 12 MHz after quadrature, enabling rapid and precise interpretation of signals. Its maximum cable length is 50 feet or 15 meters. Where in applications more distance is required in installations, extra voltage regulator must be employed to maintain system reliability.

The system operates from a 5 VDC power source to achieve low-power integration. It is A-quad-B and marker signal type supported, differential or open collector, for interfacing. Single-ended interfaces should be shunned where differential signaling is employed in a way that may lead to signal integrity issues. The frequency of encoder output is up to 3 MHz, and this is highly compatible with typical encoder types that are commonly used in automation systems. This model has a 55 mA AC-RMS drive current limit when driving with resolvers, with effective current control over driven elements. Position resolution is 18 bits when velocity controlling and 16 bits when motoring with resolvers, allowing highly accurate control of motor speed and positioning. The drive is less than 20 arcminutes accurate in temperature-limited mode when used on certain resolvers, offering stable performance in various thermal environments. For sine encoders, the drive has 256x cycle decomposition of the interpolation to ensure that signal resolution and output smoothness are maximized. The feature keeps noise to a minimum and allows for maximum feedback in highly tuned applications.

The PRD-0045000z-25 is geared towards precision-based applications where accurate feedback, high-frequency processing, and signal integrity are of primary concern. It combines encoder flexibility, high-resolution feedback, and efficient current handling in a compact drive platform, offering harsh motion applications reliability and performance. Its electrically transparent guidelines ensure safe installation and best performance in sensitive control systems.
