4. ROTACOD Absolute encoders
Absolute encoder generates a digital signal related to the position of a rotary axis
The value of the signal is transmitted to a control logic that manages the received data
In presence of a power supply fail the physical position is not lost
The zero setting of the mechanical part is required only in the initial installation
No batteries or memories required to keep the position absolute value

6. ROTACOD Absolute encoders
Working Principle
The source of signals is a disc with a grated design forming tracks
Tracks have zones where light can pass through and obscured tracks through which light cannot pass
The light emitted by a lighting source go through the disc and is collected by a photo-diode on disc’s other side
While disc is rotating the photo-diode detects light variations, switching the output signal on and off

7. ROTACOD Absolute encoders
Working Principle
Using multiple tracks, the combination of On and Off of the single tracks generates an absolute value of position
As power is turned On, this value position is read from tracks and immediately sent to the output circuit
If disc has 12 tracks then positions (4096 info/revolution) are available.
No repetitions of combinations of 1 and 0 are present on disc (unique code).
The main disc uses a Gray code as pattern
Track 1
Track 12

each line data line is a bit
1 = bit high / 0 = bit low
the combination of 1 and 0 gives a coded value (position) to the control unit

14. ROTACOD Absolute encoders
The value sent to the control unit can be as follows:
BINARY (more bits can change at the same time)
GRAY (successive values change a bit per time maximum)
BCD (binary code for each single number)
The absolute value can be sent to the control in several interfaces:
Parallel
PROS: faster CONS: many wires to connect
Serial
PROS: few wires to connect CONS: speed reduced
Field-bus
PROS: several devices on the same line, bi-directional data transmission CONS: more sophisticated electronics
Value is read by the control and used for positioning and control of motors installed on the machinery
