24-Analog Command Select - Selects the type of external
speed reference command the control should be expecting to
see in your application. The possible values are 0-10V, 0-5V,
0-20mA, and 4- 20mA. If long distances are required between
the control and the external speed command location then 0-20
mA or 4-20mA should be considered since a current loop
command scheme will allow no loss of the command signal with
long cable lengths.
Also sets if the control will recognize a high value of command
signal as a high output command or a low output command of
the inverter. If Direct is selected the control will see a low
command signal as a low speed command and a high command
signal as a high speed command. Direct is the selection used in
most applications. If Inverted is selected the control will see a
low command signal as a high speed command and a high
command signal as a low speed command.
