Example: Commissioning auxiliary axes

Commissioning for configuration example 1

1. Activate the auxiliary axes by setting the following machine data:

– MD30460 $MA_BASE_FUNCTION_MASK bit 8 = 1 for each auxiliary axis "MQ2"

– MD20070 $MC_AXCONF_MACHAX_USED[n] = 8

– MD11240 $MN_PROFIBUS_SDB_NUMBER = 2, to select the associated system data

2. The device name of the SINAMICS Control Unit is automatically entered by the SDB: MQ2

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

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.

block (SDB).
