STANDSTILL MONITOR LH5946.48PC/61 20-400mV UH AC115V (0064469)
The safe sensorless LH 5946 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.
Applications
Safe standstill detection on 3- and single-phase motors, e.g. to enable gate interlocks on machine tools or to activate hold in brakes.
