Description:
Number of encoder revolutions a rotary absolute encoder is able to resolve (see also
the maximum multiturn information of the absolute encoder, see encoder data sheet or
PROFIdrive parameter P979).
The absolute position of a rotary axis is reduced to this resolvable range when an
absolute encoder is switched on:
In other words, a MODULO transformation takes place if the actual position sensed is
larger than the position permitted by MD ENC_ABS_TURNS_MODULO.
0 degrees <= position <= n*360 degrees (with n = ENC_ABS_TURNS_MODULO)
Note:
With SW 2.2, the position is reduced to this range when the control/encoder is switched
on. With SW 3.6 and higher, half of this value represents the maximum permissible
travel distance with the control swiched off/the encoder inactive.
Special cases:
For PROFIdrive, any integer value is permissible.
The MD is relevant only for rotary encoders (on linear and rotary axes).
Corresponds to:
