10203 Channel %1 NC start without reference point (action=%2<ALNX>)
Parameters: %1 = Channel number
%2 = Action number/action name
Definitions: NC start has been activated in the MDI or AUTOMATIC mode and at least one axis that needs to be
referenced has not reached its reference point.
Reaction: Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Via the channel-specific MD 20700:
REFP_NC_START_LOCK (NC Start without reference point) you can decide whether the axis must
be referenced before NC Start or not. The start of referencing can be enabled channel-specific or axis-
specific.
Channel-specific reference point approach: The rising edge of the interface signal "activate
referencing" (DB 21 - 28, DBX 1.0) starts an automatic sequence which starts the axes of the channel
in the same sequence as specified in the axis-specific MD 34110 REFP_CYCLE_NR (axis sequence
channel-specific referencing). 0: The axis does not participate in channel-specific referencing, but it
must be referenced for NC Start, -1: The axis does not participate in channel-specific referencing, but
it need not be referenced for NC Start, 1- 8: Starting sequence for the channel-specific referencing
(simultaneous start at the same no.), 1 - 31: CPU type
Axis-specific referencing: Press the direction key that corresponds to the approach direction in the
axis-specific MD 34010 REFP_CAM_MDIR_IS_MINUS (reference point approach in minus direction).
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
