947 The machine parameters have been
erased and the PLC program is
missing.
2877 The operating states Automatic,
SRG, SBH, and SH of the MCU and
CCU are compared cyclically. If the
values remain unequal for longer
than 200 ms, a Stop 1 is released.
40 The axis is moving at least 4 times
slower or faster than commanded
by the nominal speed command
output.
43 The motor is moving while the axis
slides are stationary or vice versa.
522 FK programming: Relative references
are possible only to the last
64 positioning blocks:
A reference is made to a more
distant block.
A reference is made to a block,
which at that point in the program,
would lead to more than one FK
solution.
523 FK programming: You programmed
a relative reference to a CC block.
1125 FK programming: You have
attempted to delete a part-program
block to which another block refers.
863 The workpiece blank cannot be
displayed:
The workpiece blank is not fully
defined.
One edge has a negative length.
The longest edge is too large or too
small.
Ratio of edge lengths is excessive.
2509 Probing cycle for workpiece
measurement: Tolerance for hole
diameter exceeded.
Cycle 208: The programmed hole
diameter (Q335) cannot be
machined with the active tool.
2508 Probing cycle for workpiece
measurement: Hole diameter too
small for tolerance.
Measured motor temperature is
too high.
No temperature sensor.
Motor encoder cable is defective.
Entry in motor table is incorrect.
Incorrect or defective temperature
sensor was installed.
Hardware defective.
Incorrect software version.
Corrective action
Enter new operating parameters.
Press CE to acknowledge the error
message.
Switch on the machine.
Inform your service agency.
Check software version.
Check machine parameter 1140.x .
Inform your service agency.
Check MP2800.x.
Inform your service agency.
Change the relative reference.
Change the relative reference.
First edit the referring block, then
delete the reference.
Edit the part program.
Check the workpiece, and if
necessary the measuring log.
Cycle 208: Use larger tool: Hole
diameter must not be larger than
twice tool diameter.
Check the workpiece, and if
necessary the measuring log.
Let the motor cool down.
Inform your service agency.
Check the motor encoder cable.
Check the entry in the motor table.
Measure the temperature sensor
(2000[Ohm] at 25[°C])
Inform your service agency.
Check software version.
Exchange drive control board.
