Increase the interpolator cycle time, i.e. modify one of the following MDs on all NCUs.
IPO_SYSCLOCK_TIME_RATIO
SYSCLOCK_CYCLE_TIME
Switch control OFF - ON.
NCU link: synchronization cycle signal failure %1 times
%1 = Number of cycles
Error message of the NCU link module that does not occur at NCU 1. The NCU's are syn-
chronized via their own NCU-link clock line. A large number of cycle signals are missing.
The parameter indicates how many cycles have failed.
- Alarm display.
- Interface signals are set.
- NC not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
Check the hardware.
Switch control OFF - ON.
NCU link: too many link axes configured %1
%1 = Number of link axis connections
Unfortunately, the communication capacity of the NCU link is insufficient for this link axis
configuration.
The link axis configuration is determined by the following MDs:
• $MN_AXCONF_LOGIC_MACHAX_TAB
• $MN_AXCT_AXCONF_ASSIGN_TAB1 ... and all further container def.
- Alarm display.
- Interface signals are set.
- NC not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
Connect a smaller number of axes across the link or combine the axes in fewer contain-
ers.
Machine data to be changed:
• $MN_AXCONF_LOGIC_MACHAX_TAB
• $MN_AXCT_AXCONF_ASSIGN_TAB1 ... and all further container def.
Switch control OFF - ON.
Serious alarm on NCU %1, axes in follow-up mode
%1 = NCU number
All axes are trailing because of a serious alarm on another NCU.
- Alarm display.
- NC not ready.
- Mode group not ready, also effective for single axes
- Interface signals are set.
- NC Start disable in this channel.
- NC Stop on alarm.
Acknowledge the alarm on the NCU.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
