Chapter 9 Parameter Descriptions
description of I/O hardware that is present on this drive and is controlled by the
inverter.
Sets the lowest input value to the user-configurable analog input 1 scaling block.
See Analog In 1 Hi (322) for more information and a scaling example.
Analog In 1 Hi sets the highest input value to the user-configurable analog input
1 scaling block. See
AC Line I/O Board Description (Frame 3 Only) on page 25
through Combined I/O Board Description (Frame 4 Only) on page 29 for a
description of I/O hardware that is present on this drive and is controlled by the
inverter.
Selects drive response when an analog signal loss is detected on user-configurable
analog input 1:
Analog Input Scaling Example
Assume:
Speed Ref A Sel = Analog In 1
Minimum Freq = 0 Hz
Maximum Freq = 60 Hz
Analog In 1 Lo = 0.0V
Analog In 1 Hi = 10.0V
This is the default setting, where minimum input (0V) represents Minimum
Speed and maximum input (10V) represents Maximum Speed.
323 Analog In 1 Lo
Range: 4.000...20.000 mA [0.001 mA]
-/+10.000V [0.1V]
0.0...10.000V [0.1V]
Default: 4 mA
Access: 0 Path: Inputs & Outputs > Analog Inputs

324 Analog In 1 Loss
Range: 0 = Disabled
1 = Fault
2 = Hold Input (use last frequency command)
3 = Set Input Lo (use Minimum Speed as frequency command)
4 = Set Input Hi (use Maximum Speed as frequency command)
5 = Goto Preset1 (use Preset 1 as frequency command)
6 = Hold OutFreq (maintain last output frequency)
Default: 0 = Disabled
