Analog I/O
AnalogI/Oisonly availableon Stand-AloneDrives.This group ofparameters containsthe
programming options for analog drive inputs/outputs.
[Anlg In 0 Lo]
[Anlg In 1 Lo]
[Anlg In 2 Lo]
Sets the percentage of voltage or current from Input 0, 1
or 2 that represents [Minimum Freq].
Parameter Number 237, 239, 248
Parameter Type Read and Write
Display Units / Drive Units 0.1% / 4096 = 100%
Factory Default 0.0%
Minimum Value –300.0%
Maximum Value +300.0%
[Anlg In 0 Hi]
[Anlg In 1 Hi]
[Anlg In 2 Hi]
Sets the percentage of voltage or current from Input 0, 1
or 2 that represents [Maximum Freq].
Parameter Number 238, 240, 249
Parameter Type Read and Write
Display Units / Drive Units 0.1% / 4096 = 100%
Factory Default 100.0%
Minimum Value –300.0%
Maximum Value +300.0%
[Analog Trim En] – Stand-Alone Version Only
ThisparameterenablesAnalogIn0asatriminput.Setting
this parameter to “Enable” creates a trim signal to the ac-
tive frequency source at Analog In 0. The trim value is
±10% of [Maximum Freq].
Minimum Input = –10% Trim
Mid-Point Input = No Trim
Maximum Input = +10% Trim
Parameter Number 90
Parameter Type Read and Write
Factory Default “Disabled”
Units Display Drive
“Disabled” 0
“Enabled” 1
[Anlg Signal Loss]
Selects the drive reaction to a loss of analog input
signal. This signal could represent commanded
frequency, PI feedback, or others.
Bits 0-2 define the input as a pot with wiper loss
detect and will generate an “Open Pot Fault” (F09).
Bits3-5definetheinputasoffset(4mA,2V)withloss
detect below that value (see below).
Parameter Number 250
Parameter Type Read and Write
[4-20mA Loss Sel]
This parameter selects the drives response to a loss of
analoginputsignal(inputbelow2Vor4mA).Requiresthat
the loss selection bitsfor [Anlg Signal Loss] beset to “1.”
This function is active only when the input is configured
in [Freq Select 1/2], [PI Ref Select], [PI Fdbk Select].
Important: Depending on the type of input configuration
(i.e. Frequency or PI), the resultant action will vary (see
“Action” column at right).
Whenconfiguredin[PIRefSelect]or[PIFdbkSelect],only
thealarmand faultconditionswill occur.Thedrivewill not
perform a speed change.
