Safe standstill monitoring and speed monitoring, sensorless option

Standstill and Speed Monitoring

Standstill and speed monitoring devices detect and signal the standstill and speed of machines and systems in automatic as well as set up operation. DOLD offers efficient and economical solutions for safe sensorless drive monitoring as well as speed monitoring using proximity sensors.

 

Sensorless safety standstill monitoring recognizes motor standstills independent of the direction of rotation, without having to use additional external sensors like encoders or proximity sensors. Standstill and speed are recognised directly through evaluating the voltage on the motor terminals. Safe speed monitoring using drive proximity sensors is used in machines and apparatus which can pose a threat to people whilst running through mobile machinery or movable parts. Standstill and speed monitoring by DOLD offers the highest safety up to Cat. 4 / PL e or SIL 3.
