P038 [Speed Reference] Related Parameter(s): d001 , d002 , d012 , d020 , d021 , P039 , P040 ,
A051 - A054 , A069 , A070 - A077 , A110 - A113 , A123 , A132 , A140 - A147 , A150 - A157
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 A051 - A054 [Digital Inx Sel] is set
to option 2, 4, 5, 6, 11, 12, 13, 14, 15 and the digital input is active, or if A132 [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 1-23 for more information on speed reference control priority.
Options 0 “Drive Pot” (Default) Frequency command from the potentiometer on the integral
keypad.
Important: This option is not available with IP66, NEMA/UL
Type 4X rated drives. Internal frequency command comes
from
A069 [Internal Freq].
1 “InternalFreq”
(IP66, NEMA/UL Type
4X Default)
Internal frequency command from A069 [Internal Freq]. Must
be set when using MOP function.
2 “0-10V Input” External frequency command from the 0-10V or ±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 A070 - A077
[Preset Freq x] when A051 - A054 [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 C for details.
6 “Stp Logic” External frequency command as defined by A070 - A077
[Preset Freq x] and A140 - A147 [Stp Logic x].
7 “Anlg In Mult” External frequency command as defined by the product of the
analog inputs (shown in
d020 [Analog In 0-10V] and d021
[Analog In 4-20mA]).
[Analog In 0-10V]

P039 [Accel Time 1] Related Parameter(s): P038 , P040 , A051 - A054 ,
A067 , A070 - A077 , A140 - A147
Sets the rate of acceleration for all speed increases.
