A001/A002 Override Sources - The inverter allows some sources to override the
settings for output frequency and the Run command in A001 and A002. This provides
flexibility for applications that occasionally need to use a different source, leaving the
standard settings in A001/A002. In particular, note the TM/PRG (Terminal/Program)
DIP switch behind the front panel cover shown below. It is the switch to the right.
The TM/PRG switch setting forces terminal operation, according to the table below:
TM/PRG
Switch Position
PRG (Program)
TM (Terminal)
When A001 = 01 and A002 = 01, the inverter control source is the terminals, regardless
of the TM/PRG switch position. When A001 and A002 setting is not 01, then the
TM/PRG switch can force terminal input control.
