P038 [Speed Reference] Related Parameter(s): b001, b002, P038, P040, P042, T051-T054,
T070
, T071, T073, T074, T075, C102, A141, A142, A143-A146, A152, d301
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 A143
- A146
[Preset Freq x] when T051
- T054 [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.
P039 [Accel Time 1] Related Parameter(s): P038, P040, T051-T054, A141, A143-A146, A147
Sets the rate of acceleration for all speed increases.
Values Default: 20.00 Secs 2.2-110 kW (3.0-150 HP)
60.00 Secs 132-250 kW (200-350 HP)
Min/Max: 0.00/600.00 Secs
