6.9.2 Automatic Cyclic Offset Adjustment
6.9.3 Offset Adjustment with Integral Factor
December 2001
The offset is adjusted automatically if the programmed time is expired and the
following conditions are fulfilled:
n
All axes are at standstill.
n
The spindle is switched off.
n
The axes are not clamped.
7 7 7 7
In MP1220, program a time after which the offset is cyclically adjusted.
If the offset voltage is greater than 1 mV, the offset is compensated in each
cycle by 1 mV.
If the offset voltage is less than 1 mV, the offset is compensated in voltage
steps of 0.15 mV.

With the integral factor you can adjust an offset automatically:
7 7 7 7
Enter an integral factor in MP1080.x. The speed with which the offset is
eliminated depends on the size of the factor.

Play in the drives can result in instability in the control loop.
In this case, enter the factor zero.
MP1080 is effective only at a standstill.
