Signals, Alarms
Required signal states
The part program can now be enabled for execution in the channel with the START
command on the condition that certain signal states exist on the machine.
The following enable signals are relevant on the VDI interface:
• DB11, ... DBX4.4 (Mode group ready) must be present
• DB11, ... DBX0.7 (mode group reset) must not be present
• DB21, ... DBX1.7 (activate program test) must not be present
• DB21, ... DBX7.0 (NC start disable) must not be present
• DB21, ... DBX7.2 (NC stop at the block limit) must not be present
• DB21, ... DBX7.3 (NC Stop) must not be present
• DB21, ... DBX7.4 (NC Stop axes plus spindle) must not be present
• DB21, ... DBX7. 7 (Reset) must not be present
• DB10, ....DBX56.1 (EMERGENCY STOP) must not be present
• No axis or NCK alarm must be active
For descriptions of the individual signals see Chapter 5.
Execution of command
The parts program or the parts program block is automatically executed and the IS:
DB21, ... DBX35.5 ("channel status active") and the
DB21, ... DBX35.0 ("program status running") is set.
The program is processed until the end of the program has been reached or the channel is
interrupted or aborted by a STOP or RESET command.
Alarms
Under certain conditions the START command will have no effect and one of the following
alarms will be triggered:
• 10200 "No NC Start permitted with active alarm"
• 10202 "No NC Start permitted with active command" (see /DA/)
• 10203 "No NC Start permitted for nonreferenced axes"
