Boot with non-calibrated encoder
For axes with non-calibrated absolute encoder:
● MD34210 $MA_ENC_REFP_STATE == 0 (encoder not calibrated)
an alarm is displayed each time the NC is booted:
● Alarm "25022 Axis <
axis identifier
> encoder <
number
> warning 0"

11.5.7 Parameterization of a 2nd measuring system with ADI4
Up to 2 measuring system can be parameterized for a machine axis. If it is not possible to
connect the 2nd measuring system directly to the associated drive module, it is possible to
use a ADI4 module.
Note
Detailed information about the measuring systems that can be connected to the ADI4 is to
be found in:
