Info

Option CardsSin/Cos Encoders• Incremental• Collimated light is passed through a scanning reticle• As the graduated disk spins the light is modulated.• If the gaps in the gratings are aligned light passesthrough.• If the gaps are not aligned no light passes through.• Photocells convert these variations in light intensity intosinusoidal signals, typically 2048 per rev.• The 890 processes these sin/cossignals by passing them througha 12 bit A-D Converter. This gives8,388,608 counts per revolution.56
Option CardsSin/Cos Encoders• Absolute Single Turn• Contains the sin/cos incrementalchannels.• Has an extra serial channel for Absolute positioninformation.(Endat 2.1) so that the shaft position is known on power up.• Used when position information is required but no gearboxis fitted.57
