The offset values are displayed individually for each axis in converter increments
(1 converter increment = 0.61 mV).

The offset values are transferred to the offset memory and
compensated.
The offset memory is erased and no compensation takes
place.
*
Only the current offset is compensated by means of the code number.
Subsequent offset modifications are not compensated.
16.5.2 Automatic Cyclic Offset Adjustment
In the machine parameter MP1220 the cycle time (unit [s]) is determined, after which an
offset is compensated by one converter increment (0.61 mV). To switch off the automatic
offset adjustment, enter the value 0 in the machine parameter MP1220.
*
Note:
If an offset voltage of 100 mV is reached with automatic offset adjustment, the
control switches itself off, generating the error message "GROSS POSITIONING
ERROR E".
