Definitions: The symbol variable specified in %3 is not available with active tool management. The
function GELSELT should be used with $P_TOOLP.
Reactions: - Interpreter stop
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Remedy: Modify program. If $P_TOOLP has been programmed, the GETSELT function should be
used instead.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
6434
Channel %1 block %2 NC command SETMTH not allowed because tool holder func-
tion not active
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: No master toolholder has been defined for the initial state
($MC_TOOL_MANAGEMENT_TOOLHOLDER = 0), therefore no toolholder is available.
The NC command SETMTH has neither been defined. In this setting, the tool change is
carried out referring to the master spindle. The master spindle is set with SETMS.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
Remedy: Correct the NC program (delete or replace SETMHT) or enable toolholder function via
machine data.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
6441
Writing of $P_USEKT not allowed.
Definitions: An attempt was made to write the value of $P_USEKT. This is not possible since pro-
gramming T= 'location number' with automatic setting of $P_USEKT is active.
Reactions: - Interpreter stop
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Remedy: • Make sure of how the NC is supposed to be configured! (see bit16 and bit22 in
$MC_TOOL_MANAGEMENT_MASK)
• Tool change with "Reject tool" is configured. If you now try to start this program on NC
control with T='location number' with automatic setting of $P_USEKT this will not be pos-
sible.
• Either run the part program on the appropriate NC control or edit the part program.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
6442
Channel %1 function not executable. No tool assigned to desired magazine/maga-
zine location %2.
Parameters: %1 = Channel ID
%2 = Magazine/magazine location no.
Definitions: PLC logic is presumably incorrect. Tool change with reject tool is configured. Preparatory
command is pending. Selected tool is (e.g. from PLC) unloaded from its location. PLC
acknowledges preparatory command with 'Repeat tool selection' (e.g. status =7). NCK
cannot find the tool at the magazine location specified in the PLC command.
