Parameterization Errors Spindle/Axis - Siemens Sinumerik 840C Diagnostics Manual

04/96
1012* Parameterization error drive MD (SW 3)
1012* Parameterization error NC–MD (SW 4 and higher)
S
Scan
At POWER ON and warm restart
S
Effect
Corresponding axes switched to follow-up operation
S
Machining stops
S
Interlocking of NC START
S
Mode Group Ready is removed
Explanation
Setting error in the NC machine data, e.g.
S
Too large a ratio between interpolator clockrate and position control clockrate, because MD160>8
S
Too large an internal K
– K factor (252*)
V
– Multgain (260*)
– Pulse weighting
S
Ratio of cycle rate (MD165) to setting for fine interpolation (MD160) or check of MD584* "Identifier of auxiliary
axes" is not a whole number
S
Incorrect measuring system adjustment with MD364* to MD368* (values chosen too large)
S
General parameter error in a drive MD
S
An illegal value has been entered for the pulse multiplication in connection with the high-resolution measuring
system. Permissible values are: 1, 2, 4, 8, 16, 32, 64 and 128.
S
Error in parameterization of the SI machine data.
S
Remedy
Check and new input of the corresponding machine data.
S
The AXIS service display shows the service number for the parameterization errors and therefore the exact
cause.(see Diagnostics Guide, Section Parameterization errors spindle/axis).
S
Note
Alarm "Parameterization error drive MD": up to SW 3
S
Alarm "Parameterization error NC–MD": as from SW 4
1016* MS switchover not possible
Scan
When the PLC requests a measuring system switchover
S
Effect
Interlocking of NC START
S
Interlocking of Mode Group Ready
S
Setpoint 0
S
Servo enable is withdrawn after the time in NC–MD "Cutout delay controller enable" has elapsed
S
Follow-up mode
S
Explanation
The difference between measuring system 1 and measuring system 2 is greater than the tolerance specified in
MD 1216*.
Remedy
Check the mechanical parts and find out the reason for the differences in the measuring value acquisition via the
1st and the 2nd measuring system.
Check sign change actual value 2nd measuring system MD 1824* bit 4, if necessary.
1028* Unable to set reference dimension
Scan
Negative edge of signal DB32, DL K+1, bit 6, ("Set reference dimension")
S
Effect
Interlock of NC Start
S
Setpoint 0
S
No servo enable
S
Follow-up mode
Explanation
If the "Set reference dimension" could not be performed (axis not stationary), the "Reference point reached" signal
is no longer set and also the axis-specific RESET alarm 1028* "Unable to set reference dimension" is triggered.
Remedy
Make sure that the axes are stationary.
1040* Absolute encoder defective
Scan
POWER ON
S
Effect
Interlocking of NC START
S
Interlocking of Mode Group Ready
S
Machining stops
Explanation
If a SIPOS absolute encoder with absolute submodule is fitted and the absolute encoder function is selected in MD
1808*, bit 0, the absolute position is requested by the control on POWER ON. If it is not possible to transmit an
absolute position from the encoder without any errors, this alarm is released.
