Note
The number of encoder pulses is calculated by multiplying the "increments per encoder
revolution" by the "number of revolutions" (see chapter "Resolution (Page 91)").
Number of encoder revolutions
Address
36.0
The machine data "number of encoder revolutions" is only required for absolute encoders. You use it
to define the maximum number of revolutions of this encoder. To obtain more information about
absolute encoders, start by reading the "Absolute encoder (Page 141)" section in this manual.
Single-turn encoder
Only the value "1" is possible.
Multiturn encoder
Multiturn encoder / listen in (fir tree): 2 ... 4096 in powers of 2
Multiturn encoder / listen in (right-justified): 2 ... 2
Increments/encoder revolution * number of encoder revolutions ≤ 2
Linear scale
You can also interconnect a linear scale. To do so, enter the value "1".
Total number of encoder steps
The total number of steps is not a machine data element.
Total number of steps = increments per encoder revolution * number of revolutions
