Programming

Analog I/O

This group of parameters contains the 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].

[Anlg In 0 Hi]
[Anlg In 1 Hi]
[Anlg In 2 Hi]

[Analog Trim En]

This parameter enables Analog In 0 as a trim input. 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

[Anlg Signal Loss]

Selects the drive reaction to a loss of analog input
signal. This signal could represent commanded fre-
quency, 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).

Bits 3-5 define the input as offset (4mA, 2V) with loss
detect below that value (see below).

[4-20mA Loss Sel]

This parameter selects the drives response to a loss of
analog input signal (input below 2V or 4mA). Requires that
the loss selection bits for [Anlg Signal Loss] be set 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).

When configured in [PI Ref Select] or [PI Fdbk Select], only
the alarm and fault conditions will occur. The drive will not
perform a speed change.
