4 – 36 HEIDENHAIN Service Manual iTNC 530 HSCI
C00A PWM
triangular signal
error
Hardware error: Triangular signal does not
oscillate or it oscillates at the wrong frequency.
Exchange drive-control board.
Inform your service agency.
C00B Too little
main memory
Internal software error Check the software version.
C00D Program
checksum error
An internal software or hardware error has
occurred.
Check the software version.
Exchange drive-control board.
C00E Controller
software timeout
An internal software or hardware error has
occurred.
Check the software version.
Exchange drive-control board.
Inform your service agency.
C012 Pos. contr.
cyc. time err.
MC is outputting erroneous cycle time for
CC position controller.
A hardware error has occurred.
Check machine parameter MP7600.0.
Exchange drive-control board.
C016 Double
speed not
possible
Control loop on X51 or X52 is defined as "double
speed," although the control loop on X53 or X54
is active.
Control loop on X55 or X56 is defined as "double
speed," although the control loop on X57 or X58
is active (only CC 4xx with 8 control loops).
Define the control loop on X51 or X52 as "single
speed," or deactivate the PWM output X53 or
X54.
Define the control loop on X55 or X56 is defined
as "single speed," or deactivate the PWM
output X57 or X58 (only CC 4xx with 8 control
loops).
C017 PWM
frequency too
high
For a single-speed control loop, the PWM basic
frequency set in MP2180.x is twice as high, and
the current controller cycle time set in
MP2182.x is half as high.
Check MP2180.x and MP2182.x.
Use a double-speed control loop instead of
single-speed.
C018 Master-
slave torque: Axis
assignment
incorrect
Axes in master-slave torque control are only
permitted at X15/X17 or X16/X18.
Change the axis assignment.
C2A0 Encoder
input %.2s
Incorrect entry in MP112.x or MP113.x (speed
encoder)
Internal software error
Check the entry in MP112.x or MP113.x.
Check the software version.
C300 Zn track
%.2s error
No enco
der signal
available
Interruption in motor encoder cable
Signal amplitude of motor encoder is missing or
too small.
Check connection of motor encoder.
Check the motor encoder.
Check the amplitude of the encoder signal.
See ”Speed encoders” on page 19 – 300. See ”Speed encoders” on page 19 – 300.
C310 Z1 track
%.2s error
Contamination of the motor encoder (Z1 track)
Motor encoder cable defective.
Motor control board defective
Exchange the motor.
Check the motor table entry.
Exchange the motor drive-control board.
See ”Speed encoders” on page 19 – 300. See ”Speed encoders” on page 19 – 300.
C330 Motor temp.
too high %.2s
Measured motor temperature is too high
No temperature sensor
Motor encoder cable defective.
Entry in motor table is incorrect
Incorrect or defective temperature sensor was
installed
Let the motor cool down.
Check the motor table entry.
Check the entry in the motor table.
Measure the temperature sensor.
