Danger!
For operating systems up to and including version 7.0:
When absolute value encoders are used, uncontrolled movements
of the drive are possible!
If an absolute value encoder is disconnected from the axis module
during operation, the fault OH3−TRIP occurs. If the absolute value
encoder now is connected to X8 again and a TRIP−RESET is carried
out, the drive may start up in an uncontrolled manner with a high
speed and a high torque. A SD8−TRIP will not occur, as would be
expected.
Possible consequences:

Death or severe injuries
Destruction or damage of the machine/drive
If a fault (trip) occurs during commissioning when an absolute
value encoder is used, check the history buffer C0168. If an
Sd8−TRIP is at the second or third place, a reinitialisation is
absolutely necessary. For this purpose, switch off and on again
the 24−V supply of the control electronics.
