Special features of rotary measuring systems
On rotary distancecoded measuring systems, the absolute position can only be determined
uniquely within one revolution. Depending on the mechanical mounting of the encoder, the
overtravel of the absolute position in the hardware does not always coincide with the
traversing range of the rotary axis.
Special features of modulo rotary axes
With module rotary axes, the reference point position is mapped on the parameterized
modulo range:
MD30330 MODULO_RANGE (magnitude of modulo range)
MD30340 MODULO_RANGE_START (starting position of modulo range)
Note
The reference point position is mapped onto the assigned (ghost) modulo range even with
axis function "Determination of reference point position rotary, distance-coded encoder within
the configured modulo range":
MD30455 MISC_FUNCTION_MASK (axis functions), Bit1 = 1

Machine axis moves internally when feedrate override = 100%.
If a feedrate override of 0% is specified, an abort occurs.
distance after the exit of the reference cam, the machine axis will be stopped.
