Fundamentals
15.8 Axis data
In the two axis-specific machine data:
• MD30110 CTRLOUT_MODULE_NR[0] (setpoint assignment: logic drive number)
• MD30220 ENC_MODUL_NR[n] (actual value assignment: logic drive number)
the index m for the DRIVE_LOGC_ADRESS of the drive is entered, which represents the
machine axis.
The entered value m refers to the drive whose I/O address is defined under the index n = (m-
1) in MD13050 DRIVE_LOGIC_ADDRESS[n] (see Chapter "Drive Configuration").
NCK Reset
Once the drive configuration and setpoint/actual value assignment have been
parameterized, an NCK reset must be executed to initiate a warm restart of the NC. After the
NC has powered up, the set configuration is effective.
Measuring system switchover
The interface signals
• DB31, ... DBX1.5 (position measuring system 1 selected)
• DB31, ... DBX1.6 (position measuring system 2 selected)
can be used to switch from the PLC between the two position measuring systems of a
machine axis.
