Why Choose the Pizzato CS AM12F1MU-P6 Safety Module?
The Pizzato Elettrica CS AM12F1MU-P6 is a dedicated motor standstill detection safety module from the CS AM Series, designed for machinery where hazardous access must remain restricted until motor movement has stopped. By monitoring the motor condition, the module provides a safety-related standstill signal that can be incorporated into machine guarding, interlocking and access-control systems.
The CS AM12F1MU-P6 supports safety applications up to Category 4, SIL 3 and PL e. It operates from a 24 V DC supply and provides 3 NO safety relay contacts, allowing the standstill condition to be integrated into compatible safety circuits controlling guard locking, contactors or other machine-safety functions.
Designed for industrial control panels, this version is non-programmable and uses a connector with screw terminals for secure field wiring. The CS AM12 family supports motor standstill monitoring for both single-phase and three-phase motors, with galvanic separation between the control and measuring circuits and selectable sensitivity for detecting residual motor voltage.

How Motor Standstill Safety Monitoring Works
Motor standstill monitoring is used where access to hazardous machine areas must only be permitted once dangerous movement has stopped. CS AM1 Series modules can determine motor standstill by monitoring the residual voltage generated across the motor phases as the motor slows. When the measured condition falls below the configured standstill threshold, the safety module can change the state of its safety outputs so that the associated safety control system can respond.
This method is particularly useful for guard-locking and machine-access applications because the safety function is based on the actual motor condition rather than simply assuming that motion has stopped when power is removed. The CS AM12F1MU-P6 provides 3 NO safety relay contacts and supports applications up to Category 4, SIL 3 and PL e, enabling integration into high-performance machine safety architectures when installed and configured in accordance with the manufacturer's requirements.
Typical Applications
- Motor standstill monitoring in industrial machinery.
- Guard-locking safety systems.
- Machine access control after hazardous movement has stopped.
- Rotating machinery and drive systems.
- Machine tools and machining centres.
- Packaging and production machinery.
- Conveyor and material handling systems.
- Industrial mixers and processing machinery.
- Maintenance access interlocking.
- Safety circuits requiring verified motor standstill before operator access.
