4.6 Listing of the alarms/alarm description

Alarm No.	2194
Alarm Text:	ºG36 position rotary axis missingº
Reason:	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:
	1. when the rotary axis is programmed for the first time after
	RESET or after a C axis switchover using an M function,
	2. when the rotary axis is programmed for the first time as
	from the target block of a block search with calculation.
Remedy:	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).
