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 
.
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 
 for more 
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
