Sensorless Standstill Monitor
UG 9146

The sensorless standstill monitor UG 9146 is used for sensorless monitoring of electric motors for standstill. It measures the induced voltage of the coasting motor at 2 terminals of the stator winding. If the induced voltage approaches 0, this means motor standstill for the device and the output relay switches on.

Advantages
. Fast reaction time
. Easy to retrofit
. No external sensors necessary

Features
. According to EN 60 255-1
. Standstill detection on 3- and single-phase motors
. Independent of direction
. Broken wire detection
. Forcibly guided safety contacts:
