P108 [Speed Reference] Related Parameter(s): d001 , d002 , d012 , P109 , P110 , t201 , t202 ,
A409 , A410 - A413 , t211 , t212 , t213 , t214
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
P108 [Speed Reference]. However, when t201 - t202 [Digital Inx Sel] is set to
option 2, 4, 5, 6, 11, 12, 13, 14 and the digital input is active, the speed reference commanded by
P108 [Speed Reference] will be overridden. Refer to the flowchart on page 1-19 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 A409 [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 A410 - A413
[Preset Freq x] when t201 and t202 [Digital Inx Sel] are
programmed as “Preset Frequencies” and the digital inputs
are active.
5 “Comm Port” External frequency command from the communications port.
P109 [Accel Time 1] Related Parameter(s): P108 , P110 , t201 , t202 , A401 , A410 - A413
Sets the rate of acceleration for all speed increases.
