DOLD: Safe Sensorless Standstill Monitoring
The safe sensorless standstill monitor UG 6946 from the SAFEMASTER S series detects the standstill of 3-phase and 1-phase motors independent of the direction of rotation. This means sensors such as encoders or proximity switches are not required. Access to the danger zone of a system is only possible by the enabling signal of the standstill monitor after the drive has been switched off and run down.
