Remark
• Switch off the power supply
• Replace the defective compo-
nent and connect the new one
• Switch on the power supply
• Alarm A01420
• Drive object CU:
– p0009 = 1
– p9906 = 2
– p0009 = 0
– p0977 = 1
• Device configuration
• Component comparison
• Completing the configuration
• Data backup
For p9906 = 2: Caution
Topology monitoring for all
(!) components has been
significantly reduced, so that
if DRIVE-CLiQ lines are
accidentally changed over
this will not be detected.
• Drive object component:
– p0201 = r0200
– p0010 = 0
– p0971 = 1
• Use the code number
• Completing commissioning
• Data backup
The new article number is
stored in the RAM of the
Control Unit and has to be
copied to the non-volatile
memory with p0977 = 1 and
p0971 = 1. As an alternative,
STARTER can be used to
backup data with a RAM to
ROM operation.
The component has been successfully replaced.
