Sinumerik Alarm 4035 Interpolation cycle from NCU%1 = %2 does not match NCU%3 = %4

Sinumerik Alarm 4035 Interpolation cycle from NCU%1 = %2 does not match NCU%3 = %4

Parameters:
%1 = NCU_number1
%2 = MD value of NCU_number1
%3 = NCU_number2 (with slowest IPO cycle)
%4 = MD value of NCU_number2

Definitions:
Occurs only with an NCU link system. The interpolation cycles of the NCUs specified in the alarm do not match one another. The slowest IPO cycle in interconnected NCU systems must be an integral multiple of all configured IPO cycles.

Reactions:
– Alarm display.
– Interface signals are set.
– NC not ready.
– Channel not ready.
– NC Start disable in this channel.
– NC Stop on alarm.

Remedy:
Set a suitable value in MN_IPO_SYSCLOCK_TIME_RATIO for all interconnected NCUs.

Program Continuation:
Switch control OFF – ON.
