Commissioning NC-controlled drives
6.8 Modular machine
The following preconditions are satisfied:
● The two Motor Modules are of the same type.
● The serial number is different: ⇒ In this case, another configuration is not required.
● The difference between the two Motor Modules, for example, is 9 A instead of 5 A.
Note
Do not make a permanent change in the drive system.
Before you replace the DRIVE-CLiQ component, change the comparison level.
Replacing SMI or SMx motor components
Note
The new SMI/SMx motor component must not yet be inserted!
Operating sequence:
1. You have removed the previous SMI or SMx motor component.
This motor component is missing in the actual topology. SINAMICS indicates this in the form
of a topology error alarm.
The "Commissioning" → "Drive system" → "Drive units" → "Topology" dialog shows the
previous motor component to be replaced in "gray", i.e. present only in the target topology.
2. In the "Commissioning" → "Drive system" → "Drive units" → "Topology" → "Change..." dialog,
remove the SMI/SMx motor component awaiting replacement from the target topology
using the "Delete component" (Page 195) dialog.
3. Switch off the drive system and switch on again.
4. In the "Commissioning" → "Drive system" → "Drive units" → "Topology" dialog, check
whether the SMI/SMx motor component has been removed from the target topology:
– The alarm topology error is no longer pending.
– The "Commissioning" → "Drive system" → "Drive units" → "Topology" dialog no longer
5. Switch off the drive system.
6. Plug in the new SMI/SMx motor component.
7. Switch on the drive system.
