2019* Parameterization error NC MD Reset key
2019* Parameterization error NC MD Reset key
S At POWER ON or warm restart
S The spindles concerned are switched to follow-up mode
S Machining stops
S Interlocking of NC START
S Mode Group Ready removed
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
V
) factor too large due to
– 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 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 Alarm “Parameterization error drive MD”: up to SW 3
S Alarm “Parameterization error NC–MD”: as from SW 4
2021* Spindle not synchronized Reset key
On execution of an M19 command
Machining stops
M19 was used to approach a spindle position, although the spindle had not yet been synchronized.
Synchronize the spindle; execute the M19 again.
2028* MD M19 not selected Reset key
When executing in AUTOMATIC mode or input in MDA or external
S Machining stops
“M19 S...” has been programmed in the part program although this function is not implemented in the control.
