Sensorless standstill monitor UG 9146

Sensorless standstill monitoring

The sensorless standstill monitor UG 9146 from the VARIMETER series is used for sensorless monitoring of electric motors for standstill. 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 9146 can be installed in switch cabinets with limited space as well as in retrofit applications.

- Simple retrofitting as sensorless
- No external initiators required
- Space-saving in the switch cabinet due to a width of only 22.5 mm
