Dold UG6946.02PS 20-400mV 0,2-6s | Standstill monitoring, Part N: 0068412

The safe sensorless UG 6946 standstill monitor is suitable for detects the standstill of 3-phase and 1-phase electric motors independent of the direction of rotation. This means sensors such as encoders or proximity switches are not required. The standstill monitor measures the induced voltage of the coasting motor. If the induced voltage approaches 0, this means motor standstill for the device and the output relay is activated. With a width of only 22.5 mm, the UG 6946 can be accommodated in the control panel even under tight space conditions allowing easy retrofitting. For the implementation of different operating modes, the standstill monitor also offers the possibility of bridging the standstill monitoring (muting).
