Description The function of the speed sensor is to detect shaft speed and the direction of rotation. The sensor is mounted to the end cover of an LSHT Orbital Motor and senses the speed from a magnet that is rotating inside the motor. The magnet is connected to the cardan shaft (spool valve motor) or valve drive (disc valve motor) by a shaft. Rotation of the magnet generates a rotating magnetic field that is a function of motor speed and direction. EMD-Speed sensor converts this magnetic field into output signal of speed and direction. Figure 1 Sensor principle Note: After each Power-Up the shaft...

Table 4 EMD speed sensor ordering information Order information Orbital Motor prepared for EMD speed sensor is ordered separately. The sensor generates a speed dependent pulse on D1 and a direction signal on D2. The sensor generates a speed dependent pulse on D1 and D2 with a 90° phase shift. It's not recommended to use quadrature mode for OMM orbital motors. WHITE can accept no responsibility for possible errors in catalogues, brochures, and other printed material.

Conversion Diagram It is possible to replace an Orbital Motor with EM-sensor with PNP or NPN open collector output with an Orbital Motor with EMD-sensor. Conversion diagrams show how it is possible to replace present sensor with EMD-sensor. The resistor Rl which is used in the current NPN/PNP diagram is not needed but can under certain conditions remain in the circuit: • If Rl < Udc/10 mA remove or increase the size of the resistor. In case the EM-sensor and the controller have different power supply, it is needed to modify the circuit so that the EMD-sensor has the same power supply as the controller....
