6.9 Offset adjustment
6.9.1 Offset adjustment with integral factor
6.9.2 Offset adjustment by code number
890
Digital axes:
An offset adjustment at the output of the current controller is automatically
compensated.
Analog axes:
The maximum permissible offset voltage in the control is 100 mV. If this
voltage is exceeded, the error message EXCESSIVE OFFSET IN <AXIS> appears.
With the integral factor you can adjust an offset automatically:
Enter an integral factor in MP1080.x. Depending on the size of the factor the
offset voltage will be reduced quickly or slowly.
Play in the drives can result in instability in the control loop.
In this case, enter the factor zero.
MP1080.x is effective only at a standstill.
MP1080.x
Analog axes: Integral factor for offset adjustment
Input:
Input 0 to 65 535
Digital axes: No function
Input: 0
Activate the offset adjustment with the code number 75 368.
The iTNC displays the offset values of the analog axes [mV] in the dialog line.
The displayed offset value consists of the offset values that are generated in
the motor controller and in the control.
If the values are to be automatically compensated:
Press the ENT key or the CONTINUE soft key. The control outputs a
corresponding countervoltage.
If nothing is to be changed:
Press the END soft key.
If the offset adjustment is to be switched off again:
Enter the code number 75 368 and press the NO ENT key or the CANCEL
soft key.
The offset values are saved in the control and remain safe in the event of
power interruption. After a control is exchanged, the offset adjustment must
be repeated by means of the code number.
