Consistency check
While the SINUMERIK 802D sl is powering up, a consistency check is performed on the
parameters for cyclic PROFIBUS communication that are relevant for process data
configuration:
●
NC: MD13060 DRIVE_TELEGRAM_TYPE[n] (drive telegram type)
●
Drive: p0922 (PROFIdrive telegram selection)
If the drive telegram type in MD13060 is different from the one defined in p0922, alarm
26015 "Axis %1 machine data %2[%3] value not permissible" is output (in this case, %2
corresponds to the identifier for MD13060).
Application examples
●
System variables during synchronization with a modal effect:
ID=1 WHENEVER TRUE DO $R0=$VA_LOAD[X]
●
System variables in a part program:
...
WHENEVER $VA_LOAD[X]>80 DO $AC_OVR=80
G1 G90 X200 F10000

Closed-loop control
General
The closed-loop control of an axis consists of the current and speed control loop of the drive
plus a higher-level position control loop in the NC.
The speed and current control are described in:
