There are 2 methods for parameter backup.
• Parameter Backup in the KCM-K PROM (see programming
instructions).
• The data can be read with a separate software - Paramstore
(procedure see Paramstore instructions).
9.3 KCM fuse replacement
Notes:
• Some fuses are self-resetting and require no replacement.
• Fuse replacement begins at section 9.3.4.
• It is important to discover the reason for overloading the fuse that
protects the +24 Vdc I-O supply and correct the problem prior to re-
applying power.
• Self resetting fuses may automatically reset if the problem is
resolved even without disconnecting line power.
• Drive pcb numbers are shown for identification.

Each drive uses auto-resetting fuses. Follow the next procedure to
permit reset.
9.3.2 Resetting auto-resetting fuses
1. Switch off KCM power.
2. Find the source of overload and correct the problem.

opened unless power has been removed and no explosive
atmosphere is present.
▲ Do not replace any fuse while under power.
▲ Wait 3 minutes after disconnecting KCM power prior to opening
the case.
