07.97 7 Drive Machine Data (SIMODRIVE Drive MD)
7.4 FDD/MSD-specific diagnosis/service machine data (as from SW 3)
7.4 FDD/MSD-specific diagnosis/service machine data
(as from SW 3)
7.4.1 Output of diagnosis/service machine data (as from SW 3)
The diagnosis/service machine data provide an overview and evaluation of signals and states
of the FDD/MSD drives.
7.4.2 Servo service data (SSD)
Acceleration (QEC – as from SW 4) 3000
Default value Lower output limit Upper output limit Units
– -9999999.9 9999999.9 mm/s 2
Active
at once
This machine data displays the acceleration rate at the instant at which the appropriate axis
executed the last speed zero crossing when quadrant error compensation (QEC) is active. The
display is called by means of softkey Service QEC in the "Circularity test" menu.
Note:
This machine data is effective only if one of the two quadrant error compensation modes is
active.
Compensation amplitude (QEC – as from SW 4) 3001
Default value Lower output limit Upper output limit Units
– -99999.999 99999.999 %
Active
at once
This machine data displays the compensation amplitude at the instant at which the appropriate
axis executed the last speed zero crossing when quadrant error compensation (QEC) is active.
The display is called by means of softkey Service QEC in the "Circularity test" menu.
Note:
This machine data is effective only if one of the two quadrant error compensation modes is
active.
