DIP Switch Settings
Motor Frequency & Units of
Measurement Switches
In all versions of the SED2, the DIP switches for
selecting the motor frequency and North American
or European units of measurement are located on
the control board under the I/O module. (See
Chapter 4, Access to Connection Terminals for
I/O module and control board locations.) The I/O
module, located under the operator panel,
connects to the operator panel either directly
(frame sizes A through C/IP20) or via a cable
(frame sizes D through E and all IP54 models).
Analog Input Switches
For all versions of the SED2, the DIP switches
used to configure the analog inputs are located
on the I/O module. (See Chapter 4, Access to
Connection Terminals for I/O module locations.)
The I/O module, located under the operator
panel, connects to the operator panel either
directly (frame sizes A through C/IP20) or via a
cable (frame sizes D through E and all IP54
models).
