7 Wiring Configuration Examples

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.
•
Required switch settings for analog terminals A53
or A54 are also shown.
NOTICE
When not using the optional STO feature, a jumper wire
is required between terminal 12 (or 13) and terminal 37
for the drive to operate with factory default
programming values.
