2019* Parameterization error NC MD
2019* Parameterization error NC MD
S
Scan
At POWER ON or warm restart
S
Effect
The spindles concerned are switched to follow-up mode
S
Machining stops
S
Interlocking of NC START
S
Mode Group Ready removed
Explanation
Input error in machine data, e.g.
S
Ratio of interpolator pulse to position control pulse too great because MD 160 > 80
S
Internal servo gain (K
– Servo gain factor (469*)
– Multgain (468*)
– Pulse weighting
S
No whole-number ratio between entry in MD 165 (timing ratio) and MD 160 (fine interpolation)
S
Incorrect measuring system adaptation in MD 455* to MD 456*
(values selected too large)
S
General parameterization error of a drive MD
S
Remedy
The pulse multiplication value entered for the high-resolution measuring system is impermissible. The following
values are permissible: 1, 2, 4, 8, 16, 32, 64 and 128.
S
Check and new input of the corresponding machine data.
S
Error in parameterization of the SI machine data.
S
The SPINDLE service display displays the service number for parameterization errors and with it 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
2021* Spindle not synchronized
Scan
On execution of an M19 command
Effect
Machining stops
Explanation
M19 was used to approach a spindle position, although the spindle had not yet been synchronized.
Remedy
Synchronize the spindle; execute the M19 again.
2028* MD M19 not selected
Scan
When executing in AUTOMATIC mode or input in MDA or external
S
Effect
Machining stops
"M19 S..." has been programmed in the part program although this function is not implemented in the control.
