Remedy: MD11410 $MN_SUPPRESS_ALARM_MASK, MD22680 $MC_AUTO_IPTR_LOCK and language
command IPTRLOCK
Program Con-
tinuation:
Clear alarm with the Delete key or NC START.
16951 [Channel %1: ] Search run in a protected program section.
Parameters: %1 = Channel number
Definitions: A part programmer can define protected part program sections with the language commands IPTR-
LOCK and IPTRUNLOCK. Every search run in these program sections will then be acknowledged with
alarm 16951. In other words: When the alarm appears, the user has started a search run (Serupro
type) and the search target lies in a protected area. A protected area can also be defined implicitly
with the MD22680 $MC_AUTO_IPTR_LOCK.
Note:
The alarm can only be generated if the simulation has been completed during the search run. The
alarm cannot be output immediately at the start of the search run.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: MD11410 $MN_SUPPRESS_ALARM_MASK, MD22680 $MC_AUTO_IPTR_LOCK and language
command IPTRLOCK
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
16952 [Channel %1: ] Start program command not possible due to MDI
Parameters: %1 = Channel number
Definitions: NCK is currently executing an ASUB in MDI mode. In this constellation, parts program command
"Start" is not allowed for another channel. Attention: If an asup is started from JOG, the NCK can inter-
nally change to MDI, if the NCK was previously in MDI and not in RESET. Note: Without this alarm,
the MDI buffer of the other channel would always be started.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Start ASUB in AUTO or ->JOG in AUTO
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
16954 [Channel %1: ] Block %2 programmed stop prohibited in stop delay area
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In a program area (stop delay area) that is bracketed with DELAYFSTON and DELAYFSTOF, a pro-
gram command was used that causes a stop. No commands other than G4 are permissible that might
cause a stop even though only shortly. A stop delay area can also be defined by MD11550
$MN_STOP_MODE_MASK.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: MD11550 $MN_STOP_MODE_MASK and language command DELAYFSTON DELAYFSTOF
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
16955 [Channel %1: ] Stop in stop delay area is delayed
Parameters: %1 = Channel number
Definitions: In a program area (stop delay area) that is bracketed by DELAYFSTON and DELAYFSTOF, an event
has been detected that causes a stop. The stop is delayed and executed after DELAYFSTOF. A stop
delay area can also be defined by MD11550 $MN_STOP_MODE_MASK.
Reaction: Interface signals are set.
Alarm display.
