December 2001 Offset Adjustment 6 – 151
6.9.2 Automatic Cyclic Offset Adjustment
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.

77
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.

0: No automatic adjustment
6.9.3 Offset Adjustment with Integral Factor
With the integral factor you can adjust an offset automatically:
7
77
7 Enter an integral factor in MP1080.x. The speed with which the offset is
eliminated depends on the size of the factor.

7 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.
