”G36 position rotary axis missing”

Reason:

Remedy:

The alarm only appears with modulo programming. The alarm is
triggered when a G68 is to be generated for the rotary axis in a G36
block:

when the rotary axis is programmed for the first time after
RESET or after a C axis switchover using an M function,

when the rotary axis is programmed for the first time as
from the target block of a block search with calculation.

For 1.

First program the C axis once with G0 or G01
(e.g. G0 G91 C = 0 LF).

For 2.

Choose a target block with no G36 and where the C axis is
programmed until the G36 block (additional axes in target
block is also sufficient).

Alarm No.
