Sets the source of the speed reference to the drive.
The drive speed command can be obtained from a number of different sources. The source is
normally determined by
[Speed Reference]. However, when
-
[Digital Inx Sel] is set
to option 2, 4, 5, 6, 11, 12, 13, 14, 15 and the digital input is active, the speed reference commanded
by
[Speed Reference] will be overridden. Refer to the flowchart on
for more
information on speed reference control priority.
Options
0 “Drive Pot” (Default)
Internal frequency command from the potentiometer on the
integral keypad.
1 “InternalFreq”
Internal frequency command from
[Internal Freq].
2 “0-10V Input”
External frequency command from the 0-10V analog input or
remote potentiometer.
3 “4-20mA Input”
External frequency command from the 4-20mA analog input.
4 “Preset Freq”
External frequency command as defined by
[Preset Freq x] when
and
[Digital Inx Sel] are
programmed as “Preset Frequencies” and the digital inputs
are active.
5 “Comm Port”
External frequency command from the communications port.
P039 [Accel Time 1]
Sets the rate of acceleration for all speed increases.
