Parker SSD previously owned by Eurothem Microtach Drive 5701/1 Speed Feedback Tachometer 1000 lines/rev The SSD Drives “MICROTACH” is a combination of micro-electronics and laser technology packaged into a rugged industrial housing. To provide high accuracy speed and position measurement an incremental encoder disk is used (1000 lines/rev) together with micro-electronics to facilitate the use of single fibre optic transmission of the encoder pulses. Fibre optic transmission of sensitive information in an electrically noisy environment is a simple and sensible step giving the supreme advantage of noise free signal transmission over considerable distances. Fibre optic technology has evolved to produce “user friendly” plastic fibre cable with simple connectors suitable for factory floor use. The housing is an industry standard flange mounting and includes shielded bearings as standard to discourage dirt and oil ingress whilst providing a high degree of mechanical integrity. The removable terminal end cover and cable gland are also sealed. The encoder is nominally powered by the 570 series equipment to which it is connected using standard cable (screens are not necessary) at a potential of 12.5 - 40V DC. (The power supply terminals being independent of polarity). PRINCIPLE OF OPERATION The position of an application proven incremental encoder disk mounted on the shaft of the microtach is sensed by optical receivers. The disk contains 3 tracks, A, B, and Marker. The A and B pulse trains are of the same frequency but displaced by 90 degrees. The frequency of the A and B pulse trains are proportional to the rotational speed of the shaft whilst the 90 degree phase displacement determines the direction of rotation of the shaft. The marker signal is a once per rev signal used in register position applications. The information contained in the three encoder waveforms (A, B, M) are digitally compressed into a serial data packet which is transmitted along the fibre optic at a 500khz packet rate. The receive decoding is the reverse process and will produce the three pulse trains with no distortion. The hardware for this process is contained within the 570 series product. The part is new. It was taken out of the box to get a better photo. Buy with Confidence, comes with a 60 day warranty.
