them.
x169 P19 The input values at X9 are limited. The function block DFIN limits the
input values. This causes the loss
of increments.
l Reduce the frequency on the
digital frequency connection.
l Check the settings for the slave
(C0425) and for the master
(C0030). These settings must
be identical.
x171 P21 Following error. The phase difference between set
and actual position is larger than
the following error limit set under
C1328. l Extend the following error
limit under C1328.
l Switch off monitoring
(C1329=3).
Drive cannot follow the digital
frequency (I
max
limit).
Check drive dimensioning.
x190 nErr Speed control error
(Speed out of tolerance margin
(C0576)) l Active load (e.g. for hoists) is
too high.
l Mechanical blockades on the
load side
Check drive dimensioning.
x200 NMAX Maximum system speed (C0596)
has been exceeded. l Active load (e.g. for hoists) is
too high.
l Drive is not speed−controlled,
torque is excessively limited.
l Check drive dimensioning.
l Increase torque limit, if
necessary.
l Switch off monitoring
(C0607 = 3).
0201 overrun
Task1 Time−out in task 1 (ID 2) Task processing takes longer than
the monitoring time set. l Adjust the length of the task
runtime.
l Adjust monitoring time.
l Determine the cause of
time−out by checking the task
runtime at the task monitor.
l Swap out time−critical program
parts in a slower task.
