That is normally 2. If several NCUs are connected via NCU link for e.g. rotary indexing
machines, the value
should be set to 3 on all NCUs. This will balance the transmission
rates of the setpoint values via the link.
In a master value application (e.g. line shaft), the value should be set to 4, but only
on the NCU that generates the master value. For all the other NCUs, the preset value
should be maintained at 2.
Note:
In control loops that are connected via interpolator, every increase of the value
generates a further dead-time.
When the IPO cycles of the NCUs within an NCU group are set to different values, the
link
communication will
only run in the slowest IPO cycle. The MD must be increased in
the ratio of the NCU IPO cycle to the slowest IPO cycle in the NCU group, in order to
achieve a synchronized output of the setpoint values on the drive interface. The
formula for this is as follows:
MM_SERVO_FIFO_SIZE = 2 * IPO cycle ratio + 1
Example:
In an IPO cycle ratio of 4:1, the value on the fast NCU should be set to 9 instead of
3. On the slow NCU, the value must be set to 3.

action list.
18794 MM_TRACE_VDI_SIGNAL EXP, N02, N06 -
- Trace specification of VDI signals DWORD PowerOn
NBUP
- - 0 0 0x7FFFFFFF 1/1 M
Description: The NCK sends and receives PLC VDI signals. The Trace function stores the signals which
have changed in
each interpolation cycle in an FIFO memory (first in-first out) having
a size of MM_MAX_TRACE_POINTS.
The FIFO is written to a file (for the 1st channel: ncsctr01.mpf) when a "trigger
event" occurs (e.g. Cancel Alarm key, see MD22704 $MC_TRACE_STOPTRACE_EVENT and
MD22700 $MC_TRACE_STARTTRACE_EVENT).
The machine data should be interpreted as bit mask. The corresponding VDI signals are
recorded depending on which bit is set.
Bits 1.. 6 describe which axial VDI input signals are recorded in the trace
(see .. TRACE_DATA_FUNCTION).
