Op. state of CCU
not equal MCU
2710 n The automatic SRG, SBH, and SH
operating states of the MCU and
CCU are compared cyclically. If the
values remain unequal for longer
than 200 ms, a Stop 1 is released.
n Switch on the machine and press
CE to acknowledge error message.
CCU speed greater
than SRG %.2s
3213 n Rotational speed for safety-oriented
operation too high.
n Inform your service agency.
CCU limit switch
%.1s-
57 n The calculated path of the tool
exceeds the traversing range
(software limit switch) of the
machine.
n Check the programmed
coordinates, and if necessary edit
the program.
n Check the datum, and if necessary
reset the datum.
CCU limit switch
%.1s+
55 n The calculated path of the tool
exceeds the traversing range
(software limit switch) of the
machine.
n Check the programmed
coordinates, and if necessary edit
the program.
n Check the datum, and if necessary
reset the datum.
CCU frequency too
high %.2s
45 n The maximum input frequency was
exceeded at an encoder input.
n Check input frequency of the
encoder signal.
CCU NC
temperature
outside tol.
2687 n The temperature inside the LE is
outside the permissible tolerance
range.
n Ensure adequate ventilation in the
electrical cabinet.
CCU S input signals
%d not equal
2336 n In a safe circuit, each machine
operating keystroke sends a signal
through separate inputs to two
microprocessors. In this case, one
of the inputs was not set. The
machine function cannot be
executed.
n Inform your service agency.
CCU S input signals
%d not equal 0
2612 n The safety-oriented inputs for key
switch, door contact and axis
configuration were not correctly set
during the cyclical test.
n Inform your service agency.
CCU standstill
monitoring %.2s
41 n The position deviation at standstill is
greater than the value entered in
machine parameter MP1110.x.
n Inform your service agency.
CCU feed rate
greater SRG %.2s
2376 n Feed rate for safety-oriented
operation too high.
n Inform your service agency.
CDT path not found 2320 n The path entered in OEM.SYS for
the display of cutting data (CDT
files) was not found.
n Check the entry in OEM.SYS and
change if necessary.
CHF after APPR not
permitted
277 n You programmed a chamfer (CHF)
immediately after an APPR block.
n Edit the part program.
CMA file: no active
line
497 n Error in compensation value
conversion: In the *.CMA file either
there is no active line selected or
the selected line does not exist.
n Activate line.
C block: Circle end
pos. incorrect
358 n The difference between the radius
at the end point of a C block (ISO:
The difference between the radius
at the end point of a C block (ISO:
n Check the circle end-point
coordinates.
n If necessary increase the value in
MP 7431.
CT after APPR not
permitted
276 n You programmed a tangentially
connecting circle (CT) immediately
after an APPR block.
n Edit the part program.
CYCL 210 not
permitted
2045 n Cycle 210 cannot be run in the
CIRCULAR PATTERN or LINEAR
PATTERN cycles..
n Use another fixed cycle.
CYCL 211 not
permitted
2046 n Cycle 211 cannot be run in the
CIRCULAR PATTERN or LINEAR
PATTERN cycles..
n Use another fixed cycle.
