Siemens SBM2 Absolute Encoder Module for Masterdrive

The SBM optional board (Sensor Board Multiturn / sin-/cos-Encoder) enables sin-/cos-encoder phase-angle sensors and multiturn phase-angle sensors to be connected and evaluated. Encoders with a pulse number from 4 to 16384 are supported. The usual communication protocols (EnDat and SSI) with baud rates from 100 kHz to 2 MHz are supported for the multiturn phase-angle sensor. The supply voltage for the encoders can be set to 5 V, 7.5 V or 15 V. By connecting the sense cable, the voltage at the encoder input can be monitored and adjusted in the case of long encoder cables (4-wire principle). In addition to the processing of encoder signals, the motor temperature is also sensed on this board (either a KTY or a PTC sensor). The signals A+, A-, B+, B-, zero+ and zero- are provided by the pulse encoder simulation via an additional front connector in accordance with standard RS422. The indicated number of pulses/revolution corresponds to the pulse number of the encoder or the multiturn encoder. The types ERN 1387 / 1381 (sine/cosine encoder) and EQN 1324 (multiturn encoder) each have 2048 pulses. The SBM2 board additionally enables an offset correction of the signals to be made and can therefore be used for an external encoder with a high resolution
