Siemens AG 2011 Measuring systemsBuilt-on optoelectronic rotary encodersIntroduction12/3 Siemens D 31 201212 OverviewAbsolute encoders, incremental encoders and mounting accessoriesThe built-on optoelectronic rotary encoders measure paths, angles of rotation or speeds in machines.

4 They can be used in conjunction with computerized numerical controls, programma-ble logic controllers, drives and position displays, for: SINUMERIK CNCs SIMOTION Motion Control Systems SIMATIC programmable logic controllers SINAMICS drive systems SIMODRIVE drive systems SIMOVERT MASTERDRIVES drive systems ApplicationA distinction is made between incremental and absolute measuring procedures: In the case of incremental encoders, the machine must travel to a reference point after each power-off state, as the position is not usually stored in the controller, and movements of the machine while the power is off are not recorded.

5 Absolute encoders, on the other hand, also record these movements while the power is off and return the actual position with power On. Travel to a reference point is not necessary. DesignAll encoders are available in Synchro flange and clamp flange versions. Encoders with a Synchro flange can be attached to the machine with 3 clamps or mounted with axial screws. The encoder is driven by means of a plug-in coupling or a spring disk coupling. Alternatively, pulleys can also be encoder supply voltage is 5 V DC or alternatively 10 V to 30 V DC.

6 The 10 V to 30 V DC version supports longer cable lengths. Most control systems apply the supply voltage directly on the measuring circuit connector. With SINAMICS, the power supply for the measuring systems is provided via the Sensor rotary encoders with cables, the cable length including the connector is 1 m ( ft).The following bending radii for the cables at the encoder must be complied with: One-time bending: 20 mm ( in) Continuous bending: 75 mm ( in) Siemens AG 2011 Measuring systemsBuilt-on optoelectronic rotary encodersIncremental encoders12/4 Siemens D 31 201212 FunctionIncremental encoders (sin/cos 1 Vpp/RS422/HTL) with cable and connec-tor, clamp flange or Synchro flangeIncremental encoders deliver a defined number of electrical pulses per rotation, which represent the measurement of the traveled distance or encoders operate on the principle of optoelectronic scanning of dividing disks with the transmitted light principle.

7 The light source is a light emitting diode (LED). The light-dark modulation generated as the encoder shaft rotates is picked up by photoelectronic elements. With an appropriate arrangement of the line pattern on the dividing disk connected to the shaft and the fixed aperture, the photoelectronic elements provide two trace signals A and B at 90 to one another, as well as a refer-ence signal R. The encoder electronics amplify these signals and convert them into different output following output levels are available: sin/cos 1 Vpp analog signalsBetter resolution can be achieved for encoders with sinusoidal signals by interpolating them in the higher-level controller.

8 RS422 difference signals (TTL) In the case of RS422 incremental encoders (TTL), the resolu-tion can be improved by a factor of four by means of edge evaluation. HTL (High Voltage Transistor Logic)Encoders with HTL interfaces are designed for applications with digital inputs with 24 V levels.
