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

P038

[Speed Reference]. However, when

T051

T054

[Digital Inx Sel] is set

to option 1, 2, 3, 4, 5, 8, 14, 15, 16, 17 and the digital input is active, or if

A152

[PID Ref Sel] is not set

to option 0, the speed reference commanded by

P038

[Speed Reference] will be overridden. Refer to

the flowchart on

page 1-28

for more information on speed reference control priority.

Options

0 “Drive Keypad”

Internal frequency command from the digital speed keys on
the integral keypad.

1 “InternalFreq”

Internal frequency command from

A142

[Internal Freq]. Must

be set when using MOP function.

2 “Analog In 1” (Default)

External frequency command from an analog source as
determined by

T069

[Analog In 1 Sel] and DIP Switch AI1 on

the control board. Default Dip Switch setting is 10V.

3 “Analog In 2”

External frequency command from an analog source as
determined by

T073

[Analog In 2 Sel] and DIP Switch AI2 on

the control board. Default Dip Switch setting is 10V.

4 “Preset Freq”

External frequency command as defined by

[Preset Freq x] when

[Digital Inx Sel] are

programmed as “Preset Frequencies” and the digital inputs
are active.

5 “Comm Port”

External frequency command from the communications port.
Refer to Appendix E and Appendix G for details. Parameter

C102

[Comm Format] is used to select a communications

protocol.
