5.3.2 Example: Commissioning auxiliary axes
Commissioning for configuration example 1
Procedure:
1. Activate the auxiliary axes by setting the following machine data:
– MD30460 $MA_BASE_FUNCTION_MASK bit 8 = 1 for each auxiliary axis "MQ2"
and"MQ3".
– MD20070 $MC_AXCONF_MACHAX_USED[n] = 8
–
MD11240 $MN_PROFIBUS_SDB_NUMBER = 2, to select the associated system data
block (SDB).
2. The device name of the SINAMICS Control Unit is automatically entered by the SDB: MQ2
and MQ3
If the SINAMICS Control Unit has already been initialized with a different device name,
reset the Control Unit to the factory setting. Remove the system CompactFlash card from
the CU, read it in a card reader and delete the "user" directory. The correct device name
is then entered by the SDB during startup.
3. To commission the drive, start the drive commissioning with "Commissioning" → "Drive
system" → "Drives".
4. Select "Change" to configure the drive. Continue with the commissioning as for the drives
connected to the PROFIBUS Integrated.
5. Then start the axis assignment via "Commissioning" → "Drive system" → "Drives" → "Axis
assignment".
6. Set the following axis machine data:
MD30110[0] $MA_CTRL_OUT_NR = 30 for the auxiliary axis MQ2
MD30110[0] $MA_CTRL_OUT_NR = 31 for the auxiliary axis MQ3
Axis Drive I/O address
MQ2 DR30 5260
MQ3 DR31 5300
The same applies for the encoders: MD30220[n] $MA_ENC_MODULE_NR
The associated I/O addresses are automatically entered by the SDB.
The changes in the machine data are activated with the "Reset (po)" softkey.
