1: Mains voltage
2: MODE GROUP READY
3: Fault message
Notes:
• If MODE GROUP READY changes to 0:
- the feed drives and spindle drive are brought to a standstill with a quick stop (i.e. with
max. braking current), and
- all signals transferred from the NC to the PLC are changed to the inactive state (reset
state).
• All commands given to the NC must be cancelled if MODE GROUP READY carries the 0
signal.
• MODE GROUP READY does not change to "1" after the cause of the fault has been
remedied until the 1st channel of the MODE GROUP has been reset with RESET or until
the NC is switched back on after disconnecting the power supply.
• All functions stored in the intermediate and main memories of the NC are deleted.
• The signal is output only in the 1st channel (master channel) of a mode group.
NC ALARM
1 signal: At least one channel-specific NC alarm (block-related) is present.
