Description: Sets the rotary unit MU per load revolution set by the user. For a rotary encoder, this establishes a reference between
t
he phy
sical arrangement and the user-speci󹪝c rotating unit MU.
Example:
Rotating unit LU (p2496 = 0)
Rotary encoder, 1 revolution should be broken down into mdegrees, (i.e. 1 LU = 1 mdegrees).
--> One load revolution corresponds to 360000 LU
--> p2506 = 360000
Dependency: See also: p2496
Note
When selecting a physical lengt
h unit, the drive automatically preassigns the parameter and it cannot be changed.

tment. The status is displayed using the other values.
Value: 0: Error occurred while adjusting
 1: Absolute encoder not adjusted
 2: Absolute encoder not adjusted and encoder adjustment initiated
 3: Absolute encoder adjusted
Dependency: See also: c2598, p2599, c11500
CAUTION
For rotating absolute encoders, when adjusting, a range is set up symmetrically around zero with half of the encoder
r
ange,
within which the position must be re-established after switch-o󹪜/switch-on. In this range, it is only permissible
that the encoder over󹪞ows.
After the adjustment has been completed, it must be guaranteed that the range is not exited. The reason for this is that
outside the range, there is no clear reference any longer between the encoder actual value and mechanical system.
If the home position (c2598) lies in this range, then the position actual value is set when adjusting to the home position.
Otherwise, adjustment is canceled with F07443.
There is no over󹪞ow for linear absolute encoders. This means that after the adjustment, the position can be re-
established in the complete traversing range after switch-o󹪜/switch-on. When adjusting, the position actual value is set
to the home position.
Note
To permanently accep
t the determined position o󹪜set, it must be retentively saved (p0977).
This adjustment can only be initiated for an absolute encoder.
