6.1 Introduction

The examples in this section are intended as a quick
reference for common applications.
•
Parameter settings are the regional default values
unless otherwise indicated (selected in
parameter 0-03 Regional Settings).
•
Parameters associated with the terminals and
their settings are shown next to the drawings.
6 6 •
Required switch settings for analog terminals A53
or A54 are also shown.
NOTICE
When using the optional STO feature, a jumper wire may
be required between terminal 12 (or 13) and terminal 37
for the frequency converter to operate with factory
default programming values.
NOTICE
The following examples refer only to the frequency
converter control card (right LCP), not the filter.
