DIP Switch Introduction
The inverter has three (3) internal DIP switches, located to the right of the logic connec-
tors as shown below. This section provides an introduction, and refers you to other
chapters that discuss each DIP switch in depth.

The SR/SK (Source/Sink) DIP switch configures the inverter's intelligent
inputs for sinking or sourcing type circuit. Note that the installation and
Powerup Test steps in this chapter do not require wiring the input terminals.
The SR/SK switch configuration is covered in detail in
Input Terminals" on page
The 485/OPE (RS-485/Operator) DIP switch configures the inverter's RS-
485 serial port. You can use the inverter's keypad (OPE-SRmini) either on
the inverter, or connected via a cable to the serial port. For the keypad, either
position of the 485/OPE DIP switch will work. However, communication
with "smart" operator devices requires the proper setting. Using digital
operators (such as OPE–SR or OPE–0EX requires the "OPE" setting.
Inverter control via a ModBus network communication requires the "485"
setting. See
"Connecting the Inverter to ModBus" on page B–3
details.
The TM/PRG (Terminal/Program) DIP switch affects the inverter's setting
for control sources. Parameter A001 sets the source selection for the
inverter's output frequency (motor speed). Parameter A002 selects the Run
command source (for FW and RV). These independently select among
sources such as input terminals, inverter keypad keys and potentiometer,
internal register settings, ModBus network, etc.
When the TM/PRG switch is set to PRG, parameter settings A001 and A002
are in effect. However, when the switch is in the TM (terminal) position, the
inverter uses the analog input terminals for the motor speed setting, and uses
the [FW] and/or [REV] terminals for the Run command. More information
is in
"Control Source Settings" on page
