SR469-P1-HI-A20-T – 1-Axis High-Performance Servo Drive with Tachometer Feedback for GE Fanuc Automation

In stock

Product Introduction:
The SR469-P1-HI-A20-T is the tachometer-feedback variant of the SR469-P1-HI-A20 servo drive family. The “T” suffix indicates that instead of an encoder, this module accepts a tachometer (analog velocity generator) for speed feedback. Tachometers are robust, simple, and cost-effective feedback devices that provide a voltage proportional to motor speed. This drive is ideal for applications where absolute position is not required, but precise speed control is critical, such as in winding machines, extruders, and conveyor systems.

Functional Features:
Simple Wiring: Tachometer feedback requires only two wires (plus power), making installation faster and less error-prone than encoder wiring.
Robust Feedback: Tachometers are mechanically rugged and immune to dust, oil, and vibration, making them ideal for harsh environments.
Smooth Speed Control: Provides excellent speed regulation with less than 0.1% speed ripple at full load.
No Position Drift: Since tachometers measure speed (not position), there is no cumulative position error over time.
Cost-Effective: Lower cost than encoder-based systems while still delivering high-performance speed control.
