Why Choose the Pizzato CS AM21P1VU Motor Speed Safety Module?
The Pizzato CS AM21P1VU is a programmable motor speed and direction-of-rotation safety module designed for safety-related monitoring of electric motors in industrial machinery. Part of the Pizzato CS AM series, it provides sensorless monitoring of motor speed and rotation direction together with 2 OSSD safety outputs for integration into modern machine safety architectures.
The CS AM21P1VU can monitor motor rotation speed and determine direction of rotation by evaluating electrical characteristics including residual voltage, frequency and phase shift. This sensorless approach means that its core safety functions do not require a separate external speed sensor, while a proximity sensor can additionally be used for diagnostic monitoring of mechanical transmission components.
Operating from a 24 V DC supply, the module is programmable through its USB port using Pizzato's CS AM Configurator software and uses secure screw-terminal connections. Designed for safety applications up to Category 4, PL e and SIL 3, the CS AM21P1VU provides a compact solution for safety-related motor speed supervision on demanding industrial machinery.

Programmable Safety Monitoring of Motor Speed and Rotation Direction
The Pizzato CS AM21P1VU is designed for machinery where motor speed and rotation direction must be supervised as part of the safety system. The module can monitor motor speed and determine rotation direction through electrical measurements, allowing safety outputs to respond according to configured minimum-speed, maximum-speed or rotation-direction conditions.
Programming is performed through the USB interface using Pizzato CS AM Configurator. The software provides Project, Setting and Monitor functions for configuring the module and observing operating information such as output status, motor speed and direction of rotation. An optional proximity sensor can also be incorporated to help diagnose faults in mechanical transmission components.
Typical Applications
- Safety-related motor speed monitoring.
- Motor direction-of-rotation supervision.
- Minimum and maximum safe-speed monitoring.
- Rotating industrial machinery.
- Conveyors and material-handling equipment.
- Machine tools and production machinery.
- Packaging and processing equipment.
- Transmission-component diagnostic applications using a proximity sensor.
- Machine safety systems requiring up to Category 4, PL e or SIL 3.
