Offset fine
adjustment by
code number
The axes to be compensated must be in the position control loop. --> If necessary, ask the
machine manufacturer!
The iTNC displays the offset values of the analog axes in the dialog line.
The values show the setting of the voltage in 0.15-mV steps.
Display value 10 means: 10 · 0.15 mV = 1.5 mV. The displayed offset value consists of the offset
values that are generated in the motor controller and in the control.

Note
Before you carry out an offset fine adjustment via code number, you must first adjust the
offset at the servo amplifier!
The control can compensate only ± 100 mV with the offset fine adjustment by code
number!
This corresponds to 1 % of the ± 10 V interface!!
An insufficient offset adjustment on the servo amplifier can thus not be compensated any
more with the code number adjustment.

Carry out an offset compensation. Offset adjusting via code number
compensates the current offset values. By the offset adjustment with the code
number, the current offset of the entire control loop is compensated. Later
changes in offset are not compensated.
Do not carry out an offset compensation, or end a previous compensation.
Exit the menu without making any changes.
