P g electronics offerssupplies a universal motor feedback system for servomotors from the sincos product line of stegmann gmbh, germany.This universal interface encoder, shs 170, having hollow shaft facility is suitable for electric drives. The hiper face [high performance interface] caters for commutation, rotational speed, incremental and absolute position information over several revolutions and . T the system makes it possible to carry out the fixing of the encoder to servomotor easily. The information could be transmitted for speed control with high accuracy over a distance of 100 metres, using only a small number of cable cores even at speeds of up to 3,600 rpm. It is possible to electronically assign an absolute position value to any mechanical shaft position .And it is also possible to read and store other information such as encoder temperature, motor characteristics and logistics information. The sincos system can be considered as a mixture of incremental and absolute encoder. The possible number of steps per revolution are 16,384 with error limits contained to 80 arc seconds. The construction of the encoder enables one to have shaft movements of axial +2 mm, radial +o.1mm dynamic. The unit is suitable for working temperature of 850°c and operating temperature range of -20 to +1,100°c. The universal interface for electric drives ensures reliable data transmission with high information content requiring only 8 lines and has a real-time process data channel.
