Installation Instructions
Introduction
The instructions provide information about the replacement of memory module
(ordering number: 134B0791).
A memory module is a component that stores motor and pump data, as well as
rmware and parameter settings of a frequency converter. If a frequency
converter malfunctions, the motor and pump data, rmware, and parameter
settings on this frequency converter can be copied to new frequency converters
of the same power sizes. Doing this saves the time for setting up the
frequency converters for the same applications.
A memory module is pre-installed on the frequency converter.
The data and parameter settings on a memory module are encoded les that are
protected from direct viewing.
To access les in a memory module, or transfer les between a memory module and
a PC, a memory module programmer is required. It is not included in this
package and needs to be ordered separately (ordering number: 134B0792).
