SINAMICS S List Manual (LH1), 07/2007
Description:
Sets the neutral length units LU per load revolution.
Therefore, for a rotary encoder, a reference is established between the physical arrangement and the neutral length
units LU used in the drive.
Example:
Rotary encoder, ballscrew with 10 mm/revolution, 10 mm should be broken down to units of µm (i.e. 1 LU = 1 µm).
--> One load revolution corresponds to 10000 LU
--> p2506 = 10000
Note:
The position controller can only process position setpoints in the interpolator clock cycle (IPO clock cycle) in integer
length units (LU, Length Unit). This is the reason that speed setpoints that are not a multiple integer of 1 LU per IPO
clock cycle can only be realized as an average. The result speed setpoint steps are especially noticeable for a high
loop gain or when the pre-control is active. Increasing p2506 counteracts this behavior.
Description:
Activating the adjustment and display of the status of the adjustment for absolute encoders.
Values:
0:
Error occurred while adjusting
1:
Absolute encoder not adjusted
2:
Absolute encoder not adjusted and encoder adjustment initiated
3:
Absolute encoder adjusted
Dependency:
Refer to: p2525, p2598, p2599
Caution:
For rotating absolute encoders, when adjusting, a range is set-up symmetrical around zero with half of the encoder
range, within which, the position must be re-established after powering-down/powering-up. In this range, it is only
permissible that the encoder overflows.
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 reference point (CI: p2598) lies in this range, then the position actual value is set when adjusting to the refer-
ence point. Otherwise, adjustment is canceled with F7443.
There is no overflow for linear absolute encoders. This means that after the adjustment, the position can be re-
established in the complete traversing range after powering-down/powering-up. When adjusting, the position actual
value is set to the reference point.
In order to permanently accept the values, the offset of the encoder adjustment (p2525) must be saved in a non-vol-
atile fashion (p0971, p0977).
Note:
The encoder adjustment is initiated with p2507 = 2. The status is displayed using the other values.
This adjustment can only be initiated for an absolute encoder.
