Program Continuation:

Runtime overflow for IPO cycle or position controller cycle, IP %1

%1 = Program location

The settings for the interpolation and position control cycle were modified before the last power-up such that too little computing time is now available for the requisite cyclic task. The alarm occurs immediately after power-up if too little runtime is available even when the axes are stationary and the NC program has not started. However, task overflow can occur only when computation-intensive NC functions are called during program execution.

-    NC not ready.

-    The NC switches to follow-up mode.

-    Mode group not ready, also effective for single axes

-    NC Start disable in this channel.

-    Interface signals are set.

-    Alarm display.

-    NC Stop on alarm.

-    Alarm reaction delay is canceled.

Please inform the authorized personnel/service department. Take greater care when optimizing the clock times NCK MD 10050 SYSCLOCK_CYCLE_TIME, MD 10060 POSCTRL_SYSCLOCK_TIME_RATIO and/or MD 10070 IPO_SYSCLOCK_TIME_RATIO.

The test should be performed with an NC program that represents the worst case. For safety, a margin of 15 to 25% should be added to the times determined in this way. Switch control OFF - ON.
