Error code 0003H
Error text Computing time overrun
Extension 1 1 = Bit 0 : Level 3 time slice (MONCYC) (MD 1300)
2 = Bit 1 : 4 msec time slice
4 = Bit 2 : 1 msec time slice
8 = Bit 3 : PC time slice
10 = Bit 4 : SC time slice (MD 1001)
20 = Bit 5 : IC time slice (MD 1000)
40 = Bit 6 : SI time slice (MD 1300)
A0 = Startup, synchronization
B0 = Background computing time
Extension 2
-
Explanation The computing time of the drive processor is no longer sufficient for the selected func-
tions in the specified cycle times. This error normally only occurs in conjunction with star-
tup functions in the case of default values (FFT measurement, step response).
SINUMERIK Safety Integrated: Monitoring cycle too short.
Remedy − Deactivate emergency retraction (MD 1636).
− Switch off feedforward control (MD 1004.0).
− Deactivate MIN-MAX memory (MD 1650.0).
− Reduce the number of DAC output channels (max. 1 channel).
− Deactivate variable signaling function (MD 1620.0).
− Deactivate encoder phase error compensation (MD 1011.1).
− Increase the position control cycle time on the NC.
− Increase the time slice during which the system error occurred or
− Increase lower-level time slices.
− Deselect functions, which are no longer required.
− Use performance instead of standard control module.
Error code 0004H
Error text Servo sign-of-life monitoring not updated.
Extension 1
-
Extension 2
-
Explanation Upon servo enable, the NC must update the sign-of-life monitoring in each position con-
trol cycle. In case of error, sign-of-life monitoring has not been updated for at least two
consecutive position control cycles.
Causes: NC failure, communication failure on the drive bus. Hardware error on drive
module or hardware error on NC CPU if error occurs sporadically at intervals of several
hours.
Remedy
Check cable connections, perform remedial measures (check shielding or
ground connection). Replace the NC hardware, replace the control module.
Replace the NC CPU with the "VB" version, replace the control module.
