CS AM12F1VU-P1 Pizzato CS Series Safety Module with motor standstill detection

Why Choose the Pizzato CS AM12F1VU-P1 Safety Module?

The Pizzato CS AM12F1VU-P1 is a dedicated motor standstill detection safety module designed for industrial machinery where safety-related access or control actions must occur only after hazardous motor movement has stopped. Part of the Pizzato CS AM series, it provides sensorless motor standstill monitoring with three normally open safety relay outputs for integration into machine safety circuits.

The CS AM12F1VU-P1 detects motor standstill without requiring a separate shaft-mounted speed sensor, making it suitable for applications such as guard unlocking, access control and safe intervention around rotating machinery. The CS AM family supports selectable detection thresholds and galvanic separation between the motor measurement and control circuits, providing flexible integration into industrial safety architectures.

Operating from a 24 V DC supply, the CS AM12F1VU-P1 uses a compact 45 × 99 × 114 mm housing suitable for control-panel installation. Its three safety normally open contacts, configurable restart modes and safety architecture make it a practical choice for demanding machinery requiring dependable confirmation of motor standstill.

Reliable Motor Standstill Detection for Machine Safety

Motor standstill monitoring is important on machinery where rotating or moving equipment can remain hazardous after a stop command has been issued. The Pizzato CS AM12F1VU-P1 monitors the motor condition and provides safety-related relay outputs when the required standstill condition has been established, allowing the signal to be incorporated into guard-locking and machine access-control systems.

By using a sensorless monitoring principle, the CS AM series can reduce the need for additional mechanical speed-sensing components. The module's three normally open safety contacts and flexible restart options support integration into machine safety architectures for production machinery, conveyors, rotating equipment and other applications where access must be coordinated with motor standstill.

Typical Applications

• Motor standstill monitoring on industrial machinery.
• Guard-locking and safe-access systems.
• Rotating machinery and processing equipment.
• Conveyors and material-handling systems.
• Production and packaging machinery.
• Machine access after hazardous motion has stopped.
• Industrial automation safety circuits.
