If you save the actual position value with Module 9146 and then close the
position control loop, or if the position control loop is closed and the actual
position value is then saved with Module 9146, the error message Actual
position value saved <Axis> appears. The error message triggers an
emergency stop.
n
A maximum of 16 variables can be used in the MP7530 column and in the
TEMPCOMP column of the description tables for the swivel axis geometry.
Module 9120 Starting a PLC axis
Module 9120 was expanded by an error code:
6= Feed rate not permitted
Module 9123 Traversing the reference marks of PLC axes
Module 9123 was expanded by an error code:
6= Feed rate not permitted
n
If REMOTE.PLCPASSWORDFORCED = YES in OEM.SYS, machine backup, full
backup and setup are only possible with the code word defined in
PLCPASSWORD =.

MP1152 is new:
0: I3 (control-is-ready signal acknowledgement) is passed on directly to
the NC
1: I3 is processed by the PLC before being passed on to the NC
n
The machining plane position indication (MP7500 bit 1 = 1) has been
expanded by the following swivel-axis combination:
Swivel head and rotary table: axis sequence B variable, A variable (tool
axis Z)
n
An internal EMERGENCY STOP can be simulated with the code number
FAILTEST in order to check the wiring of the machine. The control-is-ready
output is reset. The NC and PLC are no longer operable.
Danger
Hanging axes must be supported before the test in order to prevent
damage to the machine in case of error.
